Giardiasis in Dogs




Giardiasis is a disease caused by dog ​​giardia and protozoa found in the small intestine of dogs and cats in many parts of the world. Protozoa are single-celled organisms, and we still know very little about them. The Giardiasis causing protozoan called giardia in dogs Canis.




As mentioned above, we are now very little about giardia protozoa and no exception. Members animals still not sure about the best way to treat giardiasis in dogs, or even why some dogs develop giardiasis in the first place. Most experts now believe that giardia infections are very common, but that only a very limited number of dogs that never show any symptoms.




It is also not sure whether you can catch giardiasis from infected dog and strict hygiene therefore recommended when treating dogs with suspected or confirmed giardiasis. What we know for sure is that humans can be infected by the parasite giardia by drinking contaminated water and develop giardiasis.




Giardiasis Shipping for dogs




A dog can be infected by eating or drinking giardia cysts of protozoa. When the cysts reach the small intestine of dogs, it will open and release the active form of giardia protozoa. This form is called trophozoite. Giardia trophozoites using a flagellum to move, the type of hair that can be used to whip back and forth, resulting in mobility. Trophozoites attaches itself to the intestinal wall where their dog was taking root and multiply by division. Finally, a new cysts formed by how, after how long a period of time and where the dogs body formed cysts are still unknown. Kista will leave the dog through feces and is now ready to infect other dogs – or other susceptible animals.




Giardiasis symptoms in dogs




In most dogs, giardia infection does not cause disease. When disease-causing protozoa do, the main symptoms of giardiasis in dogs is diarrhea. Younger dogs seem more prone to symptoms of giardiasis grown from adult dogs. Diarrhea caused by giardiasis can be acute, intermittent or chronic. Most dogs will defend their appetite, but they can still lose weight because the diarrhea persists. In dogs, giardiasis will damage the lining of the intestine and make it difficult for the intestines to absorb nutrients from food. Giardiasis also affect the entire digestive process. Dog owners can see that their dog shit seem strange, often pale and greasy. Dirt can also spray smells even worse than that emitted from normal dog shit.




Giardiasis medicine for dogs




Because we still know little about Giardiasis, difficult to give definite guidelines on the treatment of giardiasis in dogs. Different vets use different treatment, and there is also the question of when to start treatment of giardiasis. Because many dogs carry giardia protozoa without experiencing symptoms, it’s probably not a good idea to begin to treat all dogs are going to test positive for giardia. Others pointed out that since the giardia protozoa can be transmitted from dogs to humans, all cases of giardia in dogs should be treated immediately to prevent human disease. There are also quite a lot of cases where veterinarians suspect giardiasis but failed to find giardia protozoa using testing methods available. Opinion about the case differs from vet to vet, but many will provide dogs with giardiasis if the dog is sick, point symptoms of giardiasis and other possible causes have been ruled out.






It should be noted that some of the popular Giardiasis treatment for dogs has not been approved for use in dogs by the United States Food and Drug Administration. It is also possible that treatment is available only remove a cyst from dog poop, without really killing giardia live in the intestines of dogs. Further research on dogs with giardiasis is needed before anyone can know for sure.




Fenbendazole is an antiparasitic drug that can kill several types of intestinal worms, and has been proven to help in the control of giardiasis as well. Fenbendazole can be used on its own, but a lot of vets who choose to combine with metronidazole when treating dogs with suspected giardiasis. Metronidazole known effective against some types of bacteria that cause diarrhea, so in cases where the perpetrator may giardia metronidazole can not manage the problem by killing the bacteria. Metronidazole is also around 60-70% effective in eliminating Giardia from infected dogs. Problems with her liver toxicity metronidazole is. It is also very bitter and dogs may refuse to take orally. If you have a pregnant bitch, metronidazole should not be used ideally for allegedly causing physical damage in the developing embryo.




Before Fenbendazole, veterinarians are often used to treat giardiasis quinacrine hydrochloride in dogs, but not as effective as quinacrine hydrochloride Fenbendazole and many dogs respond to treatment with vomiting, loss of appetitive, fever and weakness.



What coccidiosis?






Coccidiosis are sick dogs that can be caused by a wide array of coccidian protozoa. All coccidian protozoa that microscopic, single-celled parasites that are capable of forming spores. They owned apicomplexan Conoidasida class, and need to take animal cells to survive and proliferate. The main causes coccidiosis in dogs is isospora species, such as isospora. Canis, isospora burrowsi, isospora ohioensis, and isospora neorivolta certain that all species are able to cause infection in humans.




Coccidian protozoa usually live in the intestinal tract of the dog where it can spread to other dogs through contaminated feces. Dogs can also be exposed to coccidiosis by eating an infected network.




Puppy with coccidiosis




Most dogs infected with protozoa Coccidian not show signs of illness because their immune systems are strong enough to deal with parasites. The majority of dogs are taken to the vet for the puppy, because young puppies do not develop a strong enough immune system. Puppies suffer from coccidiosis is almost always transmitted by feces of their mother. Their immune system is immature – often combined with the stress that is transferred to a new owner, leaving the mother and siblings, and may have to travel far – allows the parasite to cause full blown coccidiosis infection.




Coccidiosis symptoms in dogs




As mentioned above, the dog can be infected Coccidian remove protozoa and cysts in her feces without showing symptoms of coccidiosis. When cysts include dogs are very young or immuno-compromised, but the parasite can cause serious problems.




Puppies infected with protozoa Coccidian often start to show symptoms when they are around 2-3 months. Early signs often diarrhea. Over time, the puppies suffer coccidiosis may develop diarrhea and dirt that can contain thick mucus, liquid and / or be very light in color. If coccidiosis infection becomes more severe, blood can be seen in dog feces. Defecation can suddenly make it impossible for the dog to stay in the house damaged.




If coccidiosis is not treated the symptoms will disappear from many dogs (but they can still pass on the disease to others), but also can cause permanent damage and even death to take your dog to the vet is highly recommended if your dog starts to show symptoms of coccidiosis. Koksidiosis very common.




Coccidiosis medicine for dogs






Coccidiosis is a very common problem, especially among children dog, but fortunately there is a wide range of effective and affordable treatment available to coccidiosis in dogs. Most drugs will affect only a few days. Even if coccidiosis infection has evolved to the point where the blood can be seen in the feces of dogs, proper treatment can prevent permanent damage to the gastrointestinal.




One of the most popular coccidiosis treatment for dogs is a family-owned drug sulfonamida. This should however be noted that some dogs can suffer damage if the tear glands treated with sulfonamida. Some vets will measure tear production before and during use sulfonamida for dogs with coccidiosis treatment. Other veterinarians choose to use without sulfonamida coccidiosis treatment.



What is Babesiosis?






Babesiosis is a rare disease in dogs, but it was not there and important for dog owners and veterinarians should jelly on Babesiosis symptoms in dogs. Babesiosis is caused by protozoan parasites of the genus Babesia and the disease is quite similar to malaria. Babesiosis is transmitted by ticks and damage red blood cells in dogs. Dogs are not the only one who can catch Babesiosis from ticks, humans are exposed as well.




The Babesia genus contains over 100 species but not all of them are contagious to dogs. In the United States, some of the dog’s dangerous Babesia species have been discovered, including the Canis Babesia and Babesia gibsoni.




Babesiosis delivery for dogs




Babesiosis transmitted to dogs through the bite of infected ticks. A lice must remain attached to the dog for at least 2-3 days to causing disease and check your dog for ticks at least once a day because of the large prevention methods against Babesiosis. Dogs can also send Babesiosis to bite other dogs, and pregnant slut can spread disease to their unborn puppies them.




Babesiosis symptoms in dogs




Babesia parasites infect red blood cells of dogs, and this will cause the dog’s immune system to kill the red blood cells are infected. This will kill the parasite Babesia, but if a large number of red blood cells are lost in the process will give your dog anemia. The immune system can also run amok and starts killing red blood cells infected too.




Babesiosis common symptoms in dogs are weakness, fever, yellow dye eye (and skin), and the urine is red or orange. Platelet count in the blood can drop significantly, which makes possible the normal blood clotting. If parasites attack the central nervous system, a dog with Babesiosis can display neurological problems, as well as local inflammation. Lungs may also be damaged by Babesiosis, and some dogs will also suffer heart problems.




Babesia treatment for dogs






Present form Babesia treatment has severe side effects, and most veterinarians to treat dogs will avoid long as they do not show symptoms. It is possible for dogs infected with Babesia without getting sick. Even with medicine, can be difficult to completely eliminate all parasites from the dog. If you have a female dog that tested positive Babesia, he can not be used to breed – even if he is completely free of symptoms.




Besides killing parasites, the vet will need to reduce the damage caused by the disease. About 50% of dogs will need blood transfusions such symptoms.




If you live in the United States, your veterinarian may use dipropionat Imidocarb

to treat your dog as this is the only Babesia drugs approved in the United States. A single dose can be enough to get rid of your dog from Babesia Canis, whereas Babesia gibsoni and other small Babesia species will require at least two doses given two weeks apart. Imidocarb dipropionat should be vaccinated and are usually quite painful for the dog. Dogs may also experience fever, muscle tremors, chills, increased heart rate, salivation, swelling of the face, agitated and tore points. Some vet because inject atropine in dogs before injecting dipropionat Imidocarb.




If you live outside the U.S., you may be able to find Aceturate Babesiosis Diminazene since this drug is a very popular treatment for Babesiosis around the world, especially for Babesia Canis. A single injection is usually enough to cure a dog if the culprit is Babesia Canis. Just like Imidocarb dipropionat, Diminazene Aceturate have serious side effects, including seizures, low blood pressure, and nausea. It is possible for a dog to death as a side effect of this drug. The self-injection also painful.




Two other drugs that are available outside the United States is sulfate Quinuronium and isetionat Phenamidine. If you fail to find isetionat Phenamidine in your home country, isetionat Pentamidine can be used as a substitute. (PHENamidine vs pentamidin.) Sulfate Quinuronium similar to malaria treatment and your dog will require two injections two separate days. In most dogs, you can see a marked improvement after the second injection with Quinuronium sulfate.




Last but not least, blue tripan can be used to restrict the entry of Babesia parasites in red blood cells of dogs. This will reduce the symptoms of Babesiosis in dogs and is given as an infusion.




Babesia Future medicine for dogs






A new type of Babesia treatment for dogs are currently being tested and has shown promising results. Treatment consists of a combination therapy where dogs given Atovaquone, Azitromycin, Quinine, and / or Clyndamycin.




Babesia vaccine for dogs




A Babesia vaccine currently available in France, but it seems to be effective only against certain strains of the parasite. Studies in France have shown the effectiveness of this vaccine is 89% of the Babesia.



Protozoal disease in dogs is an infection caused by the protozoa, one-cleed eukaryotes. Microbial eukaryotes is uniseluler which the cell has developed the core membrane bound. Protozoan infections in dogs can affect several systems and is responsible for a variety of symptoms and diseases of dogs.






Symptoms of protozoal disease in dogs




Because there is such an abundance of protozoa species capable of attacking the dog, it is difficult to give general guidelines about the symptoms to look for in your dog. Protozoan infection symptoms in your dog will also depend on the organ affected. Entry point for protozoa can for example determine where the initial symptoms are present in the dog. Below you will find a list of symptoms generally associated with protozoal disease in dogs, but because you see many of them are generally associated with a high number of other diseases, such as diseases caused by viruses and bacteria.




· Anorexia

· Blindness

· Respiratory problems

· Cough

· Diarrhea

· Enlarged lymph nodes

· Pressure

· Fever

· Muscle cramps

· Paralysis

· Cramp

· Vomiting

· Weight loss

· Yellow staining




Examples of diseases caused by protozoa dog




· Acanthamebiasis, caused by Acanthamoeba species

· Amebiasis, caused by Entamoeba histolytica

· Babesiosis, caused by Babesia species

· Balantidiasis, caused by Escherichia Balantidium

· Coccidiosis, usually caused by Cystoisospora

· Kriptosporidiosis, caused by Cryptosporidium parvum

· Cytauxzoonosis, due Cytauxzoon Felis

· Hepatozoonosis, caused by Hepatozoon Canis

· Encephalitozoonosis, due Encephalitozoo

· Giardiasis, caused by Giardia species

· Leishmaniasis, caused by Leishmania species

· Neosporosis, caused by Neospora Cani

· Pneumocystosis, caused by Pneumocystis carinii

· Toxoplasmosis, caused by Toxoplasma gondii

· Trikomoniasis, due Pentatrichomonas hominis

· Trypanosomiasis, caused by Trypanosoma cuniculinum cruzin

Ways to diagnose protozoan infections in dogs






If your vet suspects that your dog may be infected with the protozoan, it can do a test one or several efforts to determine the truth. To begin with, a veterinarian who will book a complete blood count (CBC), biochemical profile urinanalysis and. In addition, the veterinarian may decide to perform serological tests, examine your dog’s feces, had chest and abdominal X-ray taken, and / or directly involved in the identification of organisms. In order to implement the introduction of live organisms, the vet will most likely need to remove and evaluate specific cells or tissues from your dog.




How to treat a dog with protozoan infections




The exact behavior depends on the protozoa that have infected your dog, the organ affected, and how severe the infection. The type of your dog and your dog’s overall health should also be considered. (Certain line can be tolerant of a particular treatment.) In severe cases, treatment may need to be accompanied by protozoa supportif intensive treatment, and your dog may need a blood transfusion. Many species of protozoa cause severe diarrhea with a significant loss of fluids and keep hydrated dog is often one of the most important aspects of supportif intensive treatment for dogs infected with protozoa.



Rhodesian Ridgeback Dog Description






Appearance

The Rhodesian Ridgeback distinguishing faeture is a ridge of hair along the back, walking in the opposite direction to the rest of the hairs. This consists of a fan-like area formed by two whorls of hair (called “crowns”) and the slope of the shoulder back soon reach the stage of the hip. Ridge is usually about 2 inches (5 cm) in width at the widest point. It is believed to originate from the dog used by the original African dog population, which has the same butt. The first filming Ridgeback is a wall painting depicting the life Boer, located in South Africa Voortrekker Monument.




Male Ridgebacks should stand 63 cm (25 in) to 69cms (27 ins) at Withers and weighs about 85 lb (39 kg) FCI Standard), females should be 24-26 inches (61-66 cm) in height and about 70 pounds (32 kg) weight. Ridgebacks typically muscular and have made for stucco is made of red light, which should be short, dense, sleek and glossy in appearance, and not wool or silk. White received on chest and toes. The presence of black hair or beat keeper was not discussed in the AKC standard, although the elaboration of the AKC standard recorded a total black or dark brown in the mantle can not be redundant . The FCI Standard states that excessive black hair all over the mantle highly undesirable. Ridgebacks sometimes have a dark mask. Dogs nose should be black or brown (liver) in accordance with the color of the dog. No other colored nose permissible. Brown nose is a recessive gene. It is not as common as a black nose, some breeders believe the inclusion of brown noses breeding program is needed to keep the spirit of the mantle. Eyes should be round and should reflect the dog’s color: dark eyes with a black nose, yellow eyes or nose (heart) brown. Ridgebacks have a tail, a strong fine, which is usually carried in gentle curve backwards.






Original standard allowed for a variety of fur colors including Brindle and sable. Modern FCI standard calls for light red made from whole grain wheat.




Other dogs breeds also have the opposite of the feather line along the spine, including the Phu Quoc Ridgeback dog and Thai Ridgeback. The Thai Ridgeback is a mixture of Phu Quoc, historians have speculated the relationship between the Rhodesian Ridgeback and Phu Quoc to note that in the history of one type may have been imported to another .




Temperament

Rhodesian Ridgebacks loyal and intelligent and somewhat aloof with strangers. It is not to be confused with aggression, a Ridgeback from the right temperament will be more inclined to ignore, not challenge, a stranger. This breed requires positive, reward-based training, good socialization and consistency, it is often not the best choice for inexperienced dog owners. Wills Ridgebacks hard, intelligent, and many seem to have a tendency to damage, even love. They protect their owners and families. If trained properly, they can be a very good guard dog, although the specific nature should not be encouraged. Like all dogs, they can become aggressive when they are not socialized properly.




Despite their athletic, sometimes forced, exterior, Ridgeback has a sensitive side. Too harsh training methods, that might be tolerated by a sporting or working dog, will likely backfire on a Ridgeback. Corrections provided Ridgeback receive fair and permitted , and for it came from someone she knew and believed . Francis R. Barnes, who wrote the first standard in 1922, acknowledged that “rough treatment … should not be given to dogs, especially when they are young they go to species with handling of that kind ..”








Samoyed Dogs






Samoyed dog takes its name from the community Samoyedic from Siberia. These nomadic reindeer herding dog bred white fur to help with the herd, and to pull sleds when they moved. Alternative name for the breed, especially in Europe, is Bjelkier


Size
Males usually have a weight between 23-30 kg (51-66 lb), while females typically weigh 17-25 kg (37-55 lb).
Height:
AKC Standard: 21 to 23.5 inches (53-60 cm) at the shoulder for males, 19-21 inches (48-53 cm) for females.
UK Kennel Club Standard: 51-56 cm (20-22 in) for males, 46-51 cm (18-20 in) for females.


Eye
Samoyed eyes are usually black or brown and almond in shape. Blue or other color eyes can occur but are not allowed in the show ring. It is in “the brown and black” in his family, Spitz family.


Ear
Samoyed ears thick and covered with fur, triangular, and erect. They are almost always white but can often have light to dark brown color (known as “cookies”), usually around the end of the ear.





Tail
Samoyed tail is one of the breed features more discriminating. Like the Alaskan Malamute, carried curled tail behind them, however, unlike the Malamute, Samoyed tail held back really touched. This should not be a tight curl or held “flag” like, it should be done lying on the back and to one side. In cold weather, the Samoyed can sleep with their tails over their noses to provide additional warmth. Almost all of the Samoyed will allow their tails fall when they relaxed and comfortable, such as when being stroked or while eating, but will return their tails to a curl when more alert.
NZKC Standard: Tail: Long and abundant, brought back when alert, sometimes down at snack time.
UK Kennel Club Standard: Tail: Long and heavy coated, brought back and to the side when alert, sometimes down at snack time.


Coat
Samoyed has a mantle, compact double layer. The mantle consists of long, coarse hair caregivers, and straight, which appear white but have a bit of silver staining. This makes the top layer of the bottom layer is very clean and free from dirt. The bottom layer, or undercoat, consists of dense fur, soft, short and hot dog making. Undercoat is typically shed the weight once or twice a year, and this seasonal process is sometimes referred to as the “mantle blowing”. This does not mean the Samoyed will only shed during that time however, the fine hairs (versus the dense blobs warehouse during seasonal shedding) will be shed all year round, and have a tendency to stick to cloth and float in the air. The standard Samoyed may come in a mixture of biscuit and white coloring, although pure white and all biscuit dogs are common. Males typically have larger ruffs than females.


Temperament
Samoyed friendly position, makes them poor guard dog, an aggressive Samoyed is rare. With their tendency to bark, but they can be diligent watch dogs, barking whenever something approaching their area. The Samoyed is a very good friend, especially for small children or even other dogs, and they kept playing until old age. When Samoyed become bored, they can start digging. With their dog sled heritage, the Samoyed is not averse to exciting things, and Samoyed has no problem attracting trained on the same rope from running together. Samoyed also used to herd reindeer. They will instinctively act as herd dogs, and when playing with children, especially, will often try to turn and move them in a different direction. This breed is marked by alert and happy expression which has received the title of “Sammy smile” and “smiling dog.”






What is Wobbler disease?




Wobbler disease is a condition that affects the dog’s neck bone and cervical instability. Wobbler disease is not only found in dogs, horses can suffer as well. Wobbler disease term used to describe a wide range of different conditions affecting the cervical spine, because they all cause similar symptoms. Wobbler disease is also referred to as cervical spondylomyelopathy (CSM), cervical spine abnormalities (CVM), and cervical spine instability.




When young dogs develop Wobbler disease (very common in Scars Denmark) problem is usually caused by narrowing of the spinal canal, called stenosis. Studies have shown that high protein diets can contribute to the development of this problem.




When middle aged and older dogs (like Doberman dogs) develop Wobbler disease, the dog will usually have a disc bulge or herniation of the disc contents.




Dogs are commonly affected breed Wobbler disease




Wobbler disease far more common in big dogs race, especially Doberman and Great Danes. It is believed to be hereditary in dogs. The list is composed of people very vulnerable dogs to develop Wobbler disease:




Basset Hound

Borzoi

Boxer

Dalmatian

German Shepherd Dog

Doberman

Great Dane

Old english sheepdog

Rhodesian Ridgeback

Samoyed

St Bernard

Weimaraner






Symptoms of Wobbler disease in dogs




Wobbler disease symptoms tend to get worse and worse over time. If the disease is the result of trauma, but can progress very quickly.




Wobbler disease common symptoms include general weakness and crouched attitude which twisted neck down. Affected dogs can appear awkward and have trouble limbs and body coordination. In some dogs, dragging the toes of the rear foot is one of the first signs of Wobbler disease. Eventually, the disease will spread and the dog will start to show symptoms of the disease Wobbler from the front legs as well (symptoms are usually less severe than the hind legs). Some dogs will also develop neck pain.




While investigating veterinarian dog with Wobbler disease, X-rays generally show malaligned vertebrae and disc space narrowing. For a more definite diagnosis, myelogram organized as this will indicate whether the dog vertebral canal stenosis. In addition, the MRI can be used to determine the precise location of spinal cord compression. MRI will also tell the vet important details about the nature and severity of the compression.




Wobbler disease treatment for dogs






Wobbler disease treatment for dogs can be medical or surgical, and guarded prognosis for both types of treatment. The most common type of treatment for Wobbler disease is giving corticosteroids to control symptoms. This will usually be combined with strict cage rest. Surgical option is for surgical repair spinal cord compression, including dorsal decompression, vertebral stabilization, and “ventral slot technique” occurs that causes ventral decompression of the spinal cord. In a few dog operations will make Wobbler disease disappears completely, while other dogs suffer a relapse. Type of operation is technically difficult and you may need to do a little research before you find a quality surgeon. A recent study showed that electroacupuncture may be a third option for dogs suffering Wobbler disease, but further research is needed.

Giardiasis: Diagnosis, Treatment, and Prevention







What is Giardiasis?


Giardiasis is an intestinal infection caused by a parasitic protozoan (single celled organism) called Giardia lamblia. These protozoans are found in the intestines of many animals, including dogs and humans. This microscopic parasite clings to the surface of the intestine, or floats free in the mucous lining the intestine. Veterinary research documents suggest that 5% to 10% of all dogs in North America have giardiasis at any given time.


Surveys also show that about 14% of the adult dog population and over 30% of dogs under one year of age were infected at some point during their life, and thus contributed to passing along this intestinal infection to other dogs. Another Vet research article I found suggests that 100% of kennel dogs, 50% of pups, and 10% of well-cared for dogs carry giardia.


Life cycle of Giardia


        Giardia occur in two forms: a motile feeding stage that lives in the intestine, and a non-motile cyst stage that passes in the feces. The giardia trophozoite – which is the active stage of the organism – inhabits the small intestine of the dog. The trophozoite stage is tear-drop shaped, binucleated, and has four pairs of flagella. It attaches to the cells of the intestine with its adhesive disc and rapidly divides to produce a whole population of trophozoites. As they detach they may be swept down the intestine. If intestinal flow is fast then they may appear in the feces. However, if they have time, encystment occurs as the parasite travels to the large intestine. The cyst  is fairly resistant, and can survive for several months outside of a host’s body as long as sufficient moisture is provided. The cyst is oblong in shape with four nuclei that are sometimes distinctly visible. Mature cysts are usually found in the feces of infected animals. Other animals become infected by ingesting the cysts that passed from the body in feces. These ingested cysts then break open inside the small intestine to release the motile feeding stage (trophozoite). Giardia increase their numbers by each organism dividing in half which is called binary fission.
How did my dog get Giardia?
Giardia lives and reproduces in the small intestine of host animals.  Giardia trophozoites, the free living stage of the organism, form infective cysts that are passed out in the feces.  If the cysts are present in a wet or damp environment they can survive in a viable state for a few weeks to several months.  Giardia infections are transmitted via ingestion of trophozoites or cysts in contaminated water or food. If a giardia cyst is ingested, the cyst wall is broken down during the digestive process and the trophozoite stage begins to colonize the upper small intestine. Transmission also occurs by direct contact, especially with asymptomatic carriers. More recently, giardiasis has also been recognized as being able to be sexually transmitted. Giardia is so prevalent throughout North America because it is highly contagious. The ingestion of as few as one or more giardia cysts may cause the disease, as contrasted to most bacterial illnesses where hundreds to thousands of organisms must be consumed to produce illness.


What harm does Giardia do to my dog?


        Giardia causes its unpleasant effects on the body not by invading the tissues, but simply by being in the way. It multiplies to the point where it sort of paves the lining of the intestine and blocks normal digestion (malabsorption). This causes only partially digested food to get lower in the digestive tract than it should, causing diarrhea.


(Photo on Right). Scanning electron micrograph of giardia attached to the inner surface of the intestine.


What are the clinical signs associated with infection?


        The trophozoites divide to produce a large population, then they begin to interfere with the absorption of food. Clinical signs range from none in asymptomatic carriers, to mild recurring diarrhea consisting of soft, light-colored stools, to acute explosive diarrhea in severe cases. Other signs associated with giardiasis are weight loss, listlessness, fatigue, mucus in the stool, and anorexia. These signs are also associated with other diseases of the intestinal tract, and are not specific to giardiasis. These signs, together with the beginning of cyst shedding, begin about one week post-infection. There may be additional signs of large intestinal irritation, such as straining and even small amounts of blood in the feces. Usually the blood picture of affected animals is normal, though occasionally there is a slight increase in the number of white blood cells and mild anemia. Without treatment, the condition may continue, either chronically or intermittently, for weeks or months.


How can I be sure my dog has Giardia?


        Diagnosing giardia is not easy. Diagnosis can be done in one of two ways: via fecal sample by a Vet or via educated evaluation of clinical findings by the breeder/owner or the Vet. Via fecal sample is not straightforward. Even when a flare is at it’s worst, the cysts will not be shedding in every single stool. Therefore, a negative report does not rule out giardia. The most thorough way to assess is to collect a sample from every single stool produced for 48 to 72 hours and have a Vet examine it using the giardia test kit.


The giardia test is a monoclonal antibody-based ELISA for the rapid detection of Giardia lamblia cysts antigen in stool specimens and serves as an in vitro aid in the diagnosis of giardiasis.


FEATURES OF THE GIARDIA TEST



  • Rapid (results in < 1 hour)

  • Specific for giardia

  • Easy to perform

  • High standardized

  • Microwell format


        For what its worth, my own observation is that stools that are bloody and full of mucous are most likely to contain cysts. Via clinical findings is the other way to diagnose. This means the breeder/owner or Vet takes a look at the dog, evaluates the history and symptoms, and treats on that basis. If the treatment is successful, the diagnosis was accurate.


How can infection be treated for less?


        Infection may be treated using one of a number of different drugs that are available through Vet Supply Stores. The treatment of choice is often with Metronidazole (brand name Flagyl). Metronidazole has two interesting properties–the action is largely confined to the gut and it also seems to stimulate the local immune system. Metronidazole kills off the giardia and reduces the numbers to the level the dog’s immune system can handle. This is my first choice for treating giardiasis in Beagles. I purchase the Metronidazole tablets from from Lambert Vet Supply without a prescription and for a lot less money. I have seen Vet bills charging as much as $ 15.00 for two (2) 250 mg tablets. I buy a product called FISH-ZOLE which is simply the prescription Metronidazole (Rx) bottled and labeled for fish tank use. It is a bottle of 250 mg x 100 tablets of Metronidazole (Flagyl) for only $ 11.17 (current price as of 04/20/2008). These tablets are the exact same tablets that you get when your Vet prescribes this drug to your dogs. Let me make this clear, these are the exact same tablets: same size, same color, and even same markings. Recommended Dosage:  I give adult Beagles (avg. 25 lbs) one 250 mg tablet twice per day and Beagle puppies (avg. 8-12 lbs) one-half of a 250 mg tablet twice per day for a total of 5 days. In 5 days, your Beagles will be 100% FREE from giardiasis. These tablets are extremely easy to administer, and this is also the dosage which is recommended by most Vets. You will not find this medication cheaper anywhere else. Click on the picture of the FISH-ZOLE bottle to the left of this paragraph and order several bottles today. (NOTE: Lambert Vet Supply strives to promote healthly animals and help customers save lots of money on animal health care products. Here is more information about Lambert Animal Health Care, LLC.)


          Alternatively, you may want to use Fenbendazole (Safe-Guard) since you are likely already purchasing large amounts of this inexpensive and very safe medication as a treatment for deworming your dogs. This is the second favorite treatment that I use in my kennel and you can also check out the article Canine Intestinal Worms and Inexpensive Treatment to learn more about Fenbendazole and place an order for it. The exact same dosage and three-day deworming treatment using Fenbendazole for deworming Beagles will also rid your hounds of the giardia protozoan.


          Treatments from the Vet research literature that I found are shown in the table below. Whatever treatment is chosen, it is very unlikely to eliminate 100% of the infection in all dogs. Adaptations that may be made to try to improve the success rate of a treatment regime include extending the duration and dose of the treatment. Care must obviously be taken with this approach to make sure that an adequate safety margin is always maintained. Another approach is to retreat after an interval of one week. Alternatively, repeat fecal samples may be collected one week after the treatment and dogs which are still passing cysts can be identified and treated. It should be recognized that, when treating a large number of dogs, whichever of these treatment strategies is adopted, there may be one or two dogs that remain as carriers of infection that will act as a potential source for reintroducing the infection into your entire kennel.

I highly recommend that you also check out the article Coccidiosis: Diagnosis, Treatment, and Prevention to learn more about the other common protozoal infection called coccidiosis. No matter which treatment you choose to utilize, the simple fact is that it may not kill all of the cysts. A certain number of them can burrow into the lining of the intestines and go dormant. They can stay dormant for years. Due to the hard shell protecting the cysts, it is almost impossible to kill them when they are encysted in the lining of the intestines. Therefore, during times of stress, the cysts may re-activate and start to reproduce, causing another outbreak of giardiasis in your Beagle or Beagle kennel. The amount of stress needed to cause a flare seems to be highly variable with different dogs and dog breeds. Beagles are one of the hardiest breeds since they were developed as hunting hounds.


        Important Note:  A healthy dog may have been infected years before and never have shown any symptoms (asymptomatic carrier). They may occasionally shed very low numbers of cysts in stools–evaluating every stool (the WHOLE stool) for something like six months is supposed to be the conclusive way to rule out an asymptomatic carrier (someone did this with a couple dogs for a study). This would cost literally thousands of dollars! Not exactly a practical way to test. Therefore, if you suspect a protozoal infection in your Beagle(s), I recommend all of your dogs be treated for both coccidia and giardia at the same time since both protozoal infections have the exact same clinical signs and both are highly contagious.


How to eliminate giardia from your kennel or home?


Once infection is present in a kennel, control may be approached in two ways:-


1. identification, isolation and treatment of infected dogs.


2. mass treatment of all dogs.


        Option 1 is only practical where a few dogs in a discrete area have been identified as being infected and where complete isolation is feasible, either within their own block or in a specific isolation block. Such isolation includes segregation of exercise areas and these animals should be fed and cleaned after all others on the premises, preferably using separate cleaning and feeding equipment and separate staff if possible. Treatment of all dogs should commence on the same day when option 2 is adopted.


        Thorough cleaning of all kennel areas where infected dogs have access is essential. Once organic debris has been removed, thorough disinfection will help to further reduce the level of environmental contamination and reduce the risk of dogs becoming re-infected after the completion of treatment. Disinfectants containing quaternary ammonium compounds have been found to kill giardia cysts at the manufacturers’ recommended dilutions (dilutions of one disinfectant up to 1:704 were found to be effective at both low and high environmental temperatures). I disinfect all my kennels twice per month by washing everything down with a mixture consisting of 8 ounces of Clorox bleach per gallon of water. Make sure you let it set at least 20 minutes, rinse thoroughly, and then let it get completely dry before letting your Beagles use the kennels again.  Important Note:  The efficacy of killing is increased by prolonged contact time, therefore disinfectant solution should be left for 20 minutes to half an hour before being rinsed off kennel or run surfaces. Since disinfection of grass runs is impossible, such area should be regarded as contaminated for at least a month after infected dogs last had access.


        Introduction of new dogs into the infected area should be avoided until the period of treatment and fecal sample checking has been completed. It should not be overlooked that some of the infected dogs may continue to excrete low numbers of cysts even after all treatments and examinations have been completed. It is therefore important that rigorous disinfection is maintained and a careful check is kept on the condition of all treated and introduced animals.


The following are recommendations for eliminating giardia from kennels:



  • treat all dogs with Metronidazole for 5 days or Fenbendazole for 3 days (Fenbendazole is even safe to use on pregnant and lactating bitches)

  • disinfect kennel areas, etc, with quaternary ammonium disinfectants which are effective in inactivating giardia cysts

  • bathe dogs with shampoo to remove all fecal matter, rinse with water

  • rinse dogs with quaternary ammonium disinfectants, then water

  • allow kennels to dry thoroughly for several days

  • retreat with Metronidazole (Flagyl) for 5 days or Fenbendazole (Safe-Guard) for 3 days

  • treat any new dogs with Metronidazole for 5 days or Fenbendazole for 3 days even if they test negative for giardia because it is so hard to detect in fecal tests


How can infection be prevented?


        It is very difficult to prevent the entry of an infection that is known to be carried by a percentage of normal dogs into a kennel. However, an initial period of isolation for all new entrants into kennels, for perhaps ten days, would reduce the risk of an infected dog spreading a large number of cysts around the main kennel area. All dogs could be observed and any infection present, which in the case case of giardia might be exacerbated by the stress of entry in kennels, could be identified and treated before entry into the main kennels.


        Dogs should be prevented from access to foul water that may contain large numbers of cysts (e.g.: river-flooded paddocks). Small numbers of cysts may occasionally be present in the potable water supply but the risk of this being a major source of infection is small. It is best to use chlorinated water for your dogs drinking water as much as possible. If you are using non-chlorinated water from a well, lake, or stream, you need to chlorinate the water yourself. To chlorinate drinking water: Use only liquid bleach that contains 5.25% sodium hypochlorite as its only active ingredient – no soap. Use a scant 4 drops of Clorox bleach per quart of water or 2 teaspoons per 10 gallons. As an alternate method of purification, you can also boil all of your dog’s drinking water. To make sure the water is completely free from living bacteria and protozoans, you need to bring the water to a rapid boil for a minimum of five (5) minutes. Remember, cool moist conditions favor the survival of the organism; therefore, simply by keeping everything clean, disinfected, and dry you will be getting a lot further toward exterminating this nasty little one-celled parasite.


        Remember,  coccidiosis and giardiasis are both very common protozoal infestations that have the exact same clinical symptoms; therefore, I recommend that both protozoans get treated one right after the other:  coccidia for 10 days and then giardia for 5 days. Once again, I treat coccidiosis with Sulfadimethoxine (Albon) and giardiasis with Metronidazole (Flagyl), which is my 1st choice, or Fenbendazole (Safe-Guard), which is my second choice. If you are using Fenbendazole as a deworming treatment, then you are already attacking any giardia protozoans in your dogs. I deworm all hounds during the first three days of every other month using Fenbendazole (Safe-Guard). This is the exact same, three-day Fenbendazole treatment recommended by many Vets for ridding your animals of giardiasis. For more information on using Fenbendazole as a very effective, yet inexpensive dewormer read my article:  Canine Intestinal Worms and Inexpensive Treatment.


Finally there is a vaccine!!!


        Now there is a vaccine to prevent signs of disease associated with Giardia infection in dogs. Fort Dodge Animal Health was recently granted a license by the USDA for Giardia Vax®, the first vaccine to prevent disease and reduce cyst shedding caused by Giardia infection in dogs. Giardia Vax has been proven to be an aid in the prevention of disease caused by Giardia infection. Giardia Vax is safe and effective for healthy dogs eight weeks of age or older. I purchase the Giardia Vax from Lambert Vet Supply. They sell a box of 25 shots for $ 150.75 which figures out at $ 6.03 per shot (current price as of 04/20/2008). You can order a box of Giardia Vax by simply clicking on the picture of the Giardia Vax which is located below of this paragraph.


          To completely clear your Beagle kennel of the protozoan giardia once and for all, give all Beagles (adults and pups) a 5 day treatment of Metronidazole (Flagyl), followed up by a shot of Giardia Vax. Then give your Beagles an annual booster of Giardia Vax and giardiasis will be gone for good from your hounds. I highly recommend that all Beaglers order this vaccine and do the shots yourself. Giardiasis has been the most common protozoan infection in North America for the past 20 years. It is a very, highly contagious intestinal infection and is carried by both humans and all warm-bloodied animals. Be on the safe side and have your Beagle(s) vaccinated against this troublesome organism.

Signs and symptoms of Giardiasis in Dogs




Living inside the small intestine of house animals, Giardia are protozoa which can be found through the entire United States as well as in most other regions around the world. An infection with Giardia is proven to be ‘Giardiasis’. Usually, several experts they think an infection with Giardia is normal but disease is lovely rare.


The truth is there are many things that we don’t have knowledge of concerning the parasite including the few of distinct species you can find to do which of these species strikes each of our family pets. The life cycle who knew known and veterinarians discord on route frequent Giardia infections are and additionally they must be treated.


Do you know the clinical symptoms normally expected infection?


When Giardia trophozoites split to manufacture a significant population, chances are they’ll for you to avoid the accurate absorption of nutrients when the intestine, harm the damaged intestinal lining, and affect digestive function. In case a dog doesn’t have solid immune system, then a not able to fight the infection. The intensity of the infection relies on the overall dog conditioning center.


The majority of infections with Giardia are asymptomatic. Along with this rare circumstances where disease takes place, younger animals tend just to be affected, and the typical indication is actually slight repeating diarrhea derived from soft, light-colored stools. Involved with serious cases, there is a severe Explosive Diarrhea. Furthermore, it has been either intermittent, or extented. The fecal material may be abnormal, being pale, having a bad odor, as stringent as looking greasy.


Typically the infected pets or animals will not likely lessen appetite, nonetheless they may get exercise. Additional symptoms related to try giardiasis are: listlessness, weariness, mucus within the waste, and anorexia. These kind of symptoms are often related to various other diseases with this intestines, and therefore are not really specific to giardiasis. Types symptoms begin about one week post-infection, along with the to start of cyst shedding,


Further signs and symptoms of significant intestinal irritability may happen, including straining as well as very little blood within the waste materials. Commonly the blood picture of affected animals is transparent, nevertheless sometimes there is a moderate boost in the quantity of white blood cells along with moderate anemia. With maybe treatment, the condition will go on, often chronically in conjunction with intermittently, for several when it’s or months.


How one can make sure my dog has contracted Giardia?


The diagnosis of Giardiasis only works by means of fecal sample using a Vet or via intellectual evaluation of clinical findings and the breeder/owner or the Veterinary clinic. Via fecal sample is difficult. Even whenever a flare is within it’s worst, the cysts will not be shedding debts stool. Consequently, a negative report doesn’t necessarily exclude giardia. By far the most comprehensive method to examine is always to collect a sample coming from collectively stool generated for forty-eight to 72 hours and enquire of a Vet to examine it while using the giardia test kit. Test is a monoclonal antibody-based ELISA for the rapid detection of Giardia lamblia nodule antigen in stool specimens.


In contrast to a third party parasitic organisms which invade our domestic pets, Giardia may also infect Humans and may be taken very seriously if diagnosed with the veterinary. Many experts have noticed the very fact as low as 10 cysts may cause disease in humans.

Giardiasis in dogs




Article by Cristian Stan



Giardiasis is an infection with giardia that occurs in dogs. Giardia is a 1 cell parasite named protozoa. This parasite infects the little intestine in the dog. There are many ways in which a dog can get infected by this parasite.


TransmissionOne of the most well-known strategies of transmission is by way of drinking water that has infected cysts. The dogs that already are infested with the parasite can pass on the infective cysts out by way of the stool. If your dog comes in get in touch with with that stool, he gets swiftly infected. These cysts are also transmitted by way of consuming contaminated food.


SymptomsAn infection with giardia means issue in digestion. The dog that is infected eats food but doesn’t get all the nutrients in that food.


Since of that, the dog might appear to be lethargic and he can even begin to lose weight. But the clearest sign of illness is diarrhea. Even a mild diarrhea can mean infection.


DiagnosisSo that the dog can be diagnosed, the vet requirements to take a sample of his stool and analyze it. You alone can take a sample of the stool to the vet along with the dog.


The vet can also take some stool by swabbing the rectum. Occasionally the tests can be inconclusive and this is why the test ought to be repeated a couple of times. The repeated test need to be carried out a couple of days apart from the old 1. Often, the vet does the diagnosis by taking a blood sample and analyzing it.


TreatmentThere are several medications suitable to treat this disease. Metronidazole is one of the most successful. This medicine should be taken for five days. It will clean all the parasites from the dog’s intestine. Of course, there are other medications too and hey can be quite efficient but they can have side effects.

Giardiasis

September 1, 2009 tashlj



Flagellated Protozoan

Flagellated Protozoan



Pathogen: G. lamblia


Category of Pathogen : Flagellated protozoan parasite


Name of the disease caused by the pathogen: Giardia                  


Symptoms of infection: The symptoms are diarrhea, gas or flatulence, greasy stools that float, abnormal stomach or abdominal cramps, upset stomach, and nausea


Primary host(s): Animals such as dogs, cats, and birds are very common host. Humans, especially children are common hosts as well.



Life cycle of Giardia

Life cycle of Giardia



Other host(s): Other animals such as cows, beavers, and sheep are host of the infection.


Route of transmission: Transmission occurs through contaminated foods and water. It is also transmitted through oral anal sex with someone who is contaminated.


Ro: The rate of increase is about 16.29 out of 100,000 in Canada. In the United States it is about 1 in every 6,138 people.


Prevalence. The prevalence is about 2% in the United States and it is about 15-20% internationally. It has a higher prevalence in the tropic areas.


Generation time: The infection may last about 2-6 weeks. It can last longer.CM68HNCA4D01DECA308N27CAJZD7YYCAWHQ9V0CARWR2EUCADHJRICCAUTLXEKCAWSNT89CAM3MGA7CAT4S1H0CALE28JSCAUSYS2MCA183MJBCAIL58KRCAL4A20DCA82ZJ8ECASGW5FF


Mortality Rate: There is no mortality rate associated with this infection. If mortality occurs it is because of dehydration or mal nourishment, which usually occurs in infected infants.


Morbidity Rate: The morbidity rate of the infection is very moderate and involves GI symptoms. 


Is it preventable? How?  Yes, it is preventable. 1. Practice good hygiene by washing body and hands. 2. Avoid contaminated water. 3.  Avoid eating contaminated foods. 4. Avoid fecal exposure during sexual activity.


Does the disease trigger a long lasting immunity?: Yes, It has shown to have a long lasting immunity, which is why children get it more than adults. Once you have been infected it is harder to get it again.



Staining of Giardia

Staining of Giardia



When was the pathogen first described and is there evidence that it was around much earlier than that?


 It was first observed in 1681 by Antonie van Leeuwenkoek in his own stools. No, there was no real evidence it was around much longer, but because of the time frame it was found it is possible it was.


What is the economic impact of the disease? In the case of animals if effects productivity. It does not tend to impact areas that are highly developed. It could affect water supply.


Medications used for the disease:


The medications used to treat Giardia for human infection are metronidazole, tinidazole, or nitazoxanide. These medications are not recommended for pregnant women. The alternative drug used to treat Giardia is berberine sulfate.




























DrugTreatment durationPossible Side Effects
Metronidazole5–7 daysMetallic taste; nausea; vomiting; dizziness; headache; disulfiram-like effect; neutropenia
TinidazoleSingle doseMetallic taste; nausea; vomiting; belching; dizziness; headache; disulfiram-like effect
Nitazoxanide3 daysAbdominal pain; diarrhea; vomiting; headache; yellow-green discolouration of urine
Albendazole5 daysDizziness; headache; fever; nausea; vomiting; temporary hair loss

In animals like cats and lambs can recover easily from the disease, but the parasite is deadly for calves. Dogs can also be treated easily but the grasses they play in is considered contaminated for about a month and their kennels must remain clean.


The coolest thing about the disease: The coolest things I found about the disease is that even our everyday routines could not necessarily prevent us from getting infected. We may think that the water is not contaminated but can be, and the same with food. I have always said that children are the “nasty,” in the sense that they don’t know how to wash their hands good or they don’t like washing their hands at all. It is because of things like Giardiasis that we teach our kids to do so.

Giardiasis in Dogs





Giardiasis is a disease caused by dog ​​giardia and protozoa found in the small intestine of dogs and cats in many parts of the world. Protozoa are single-celled organisms, and we still know very little about them. The Giardiasis causing protozoan called giardia in dogs Canis.




As mentioned above, we are now very little about giardia protozoa and no exception. Members animals still not sure about the best way to treat giardiasis in dogs, or even why some dogs develop giardiasis in the first place. Most experts now believe that giardia infections are very common, but that only a very limited number of dogs that never show any symptoms.




It is also not sure whether you can catch giardiasis from infected dog and strict hygiene therefore recommended when treating dogs with suspected or confirmed giardiasis. What we know for sure is that humans can be infected by the parasite giardia by drinking contaminated water and develop giardiasis.




Giardiasis Shipping for dogs




A dog can be infected by eating or drinking giardia cysts of protozoa. When the cysts reach the small intestine of dogs, it will open and release the active form of giardia protozoa. This form is called trophozoite. Giardia trophozoites using a flagellum to move, the type of hair that can be used to whip back and forth, resulting in mobility. Trophozoites attaches itself to the intestinal wall where their dog was taking root and multiply by division. Finally, a new cysts formed by how, after how long a period of time and where the dogs body formed cysts are still unknown. Kista will leave the dog through feces and is now ready to infect other dogs – or other susceptible animals.




Giardiasis symptoms in dogs




In most dogs, giardia infection does not cause disease. When disease-causing protozoa do, the main symptoms of giardiasis in dogs is diarrhea. Younger dogs seem more prone to symptoms of giardiasis grown from adult dogs. Diarrhea caused by giardiasis can be acute, intermittent or chronic. Most dogs will defend their appetite, but they can still lose weight because the diarrhea persists. In dogs, giardiasis will damage the lining of the intestine and make it difficult for the intestines to absorb nutrients from food. Giardiasis also affect the entire digestive process. Dog owners can see that their dog shit seem strange, often pale and greasy. Dirt can also spray smells even worse than that emitted from normal dog shit.




Giardiasis medicine for dogs




Because we still know little about Giardiasis, difficult to give definite guidelines on the treatment of giardiasis in dogs. Different vets use different treatment, and there is also the question of when to start treatment of giardiasis. Because many dogs carry giardia protozoa without experiencing symptoms, it’s probably not a good idea to begin to treat all dogs are going to test positive for giardia. Others pointed out that since the giardia protozoa can be transmitted from dogs to humans, all cases of giardia in dogs should be treated immediately to prevent human disease. There are also quite a lot of cases where veterinarians suspect giardiasis but failed to find giardia protozoa using testing methods available. Opinion about the case differs from vet to vet, but many will provide dogs with giardiasis if the dog is sick, point symptoms of giardiasis and other possible causes have been ruled out.






It should be noted that some of the popular Giardiasis treatment for dogs has not been approved for use in dogs by the United States Food and Drug Administration. It is also possible that treatment is available only remove a cyst from dog poop, without really killing giardia live in the intestines of dogs. Further research on dogs with giardiasis is needed before anyone can know for sure.




Fenbendazole is an antiparasitic drug that can kill several types of intestinal worms, and has been proven to help in the control of giardiasis as well. Fenbendazole can be used on its own, but a lot of vets who choose to combine with metronidazole when treating dogs with suspected giardiasis. Metronidazole known effective against some types of bacteria that cause diarrhea, so in cases where the perpetrator may giardia metronidazole can not manage the problem by killing the bacteria. Metronidazole is also around 60-70% effective in eliminating Giardia from infected dogs. Problems with her liver toxicity metronidazole is. It is also very bitter and dogs may refuse to take orally. If you have a pregnant bitch, metronidazole should not be used ideally for allegedly causing physical damage in the developing embryo.




Before Fenbendazole, veterinarians are often used to treat giardiasis quinacrine hydrochloride in dogs, but not as effective as quinacrine hydrochloride Fenbendazole and many dogs respond to treatment with vomiting, loss of appetitive, fever and weakness.

Giardiasis

Giardiasis
From Wikipedia, the free encyclopedia


Classification & external resources ICD-10 A07.1
ICD-9 007.1
MedlinePlus 000288
eMedicine emerg/215


Giardiasis (also known as beaver fever) is a disease caused by the flagellate protozoan Giardia lamblia (also Giardia intestinalis). The giardia organism inhabits the digestive tract of a wide variety of domestic and wild animal species as well as humans. It is a common cause of gastroenteritis in humans, infecting approximately 200 million people worldwide.


Giardiasis is passed via the fecal-oral route. Primary routes are personal contact and contaminated water and food. People who spend time in institutional or day-care environments are more susceptible, as are travelers and those who consume improperly treated water. It is a particular danger to people hiking or backpacking in wilderness areas worldwide. Giardia is suspected to be zoonotic—communicable between animals and humans. Major reservoir hosts would include beavers, dogs, cats, horses, and cattle.


Symptoms include:


1. loss of appetite,
2. lethargy,
3. fever,
4. explosive diarrhea,
5. loose or watery stool,
6. stomach cramps
7. upset stomach,
8. projectile vomiting (uncommon),
9. bloating, and
10. flatulence.


Symptoms typically begin 1–2 weeks after infection and may wane and reappear cyclically. Symptoms are caused largely by the thick coating of Giardia organisms coating the inside of the small intestine and blocking nutrient absorption. Most people are asymptomatic; only about a third of infected people exhibit symptoms.


Treatment
Drugs used to treat adults include:



    • metronidazole,

    • albendazole and quinacrine.

    • Furazolidone and nitazoxanide may be used in children.

    • Treatment is not always necessary, as the body can defeat the infection by itself.

    • The drug tinidazole—trade name Fasigyn or Tindamax—can treat giardiasis in a single treatment of 2000 mg, instead of the longer treatment of the other medications listed. The shorter duration of treament may also cause less patient distress. Tindamax is now approved by the FDA[1] and available to U.S. patients.

    • The supplement barberry (Berberis vulgaris) can also be helpful in treating Giardiasis.[2][3]
