Intestinal Parasite (Cyptosporidia) in Dogs

Cryptosporidiosis in Dogs

Cryptosporidiosis is caused by a variety of factors and can be treated effectively with medications. The disease is caused by the ingestion of the intestinal parasite Cryptosporidium and is commonly ingested through contaminated water, food or feces.

The condition or disease described in this medical article can affect both dogs and cats. If you would like to learn more about how this disease affects cats, please visit this page in the PetMD health library.

Symptoms and Types

The most common sign of this disease is fever and diarrhea. Dogs will also display intolerance for food, or in more serious cases, organ disease. Dogs may exhibit lethargy, intolerance for exercise and weakness.

Causes

Some of the risk factors include the ingestion of contaminated food or water, the ingestion of animal feces, and intestinal infection. When the Cryptosporidium parasite is ingested in the oocyst stage, it is transferred into the body of the host (the dog). It then develops into a sporozoite, the division and development stage, and proceeds to spread and infect the cells of the host body. The disease is more a concern for puppies, as their immune systems are less developed and more susceptible to complications.

Diagnosis

A fecal examination is often performed to determine what the underlying cause is for the issue.
