The causative agent of sarcocystosis (Sarcocystis) is the same organism that causes equine protozoal meningitis. It is believe dogs can become infected with Sarcocystis; however, symptoms of disease in infected dogs are rare.
Sarcocystosis can occur in both dogs and cats. If you would like to learn how this type of infection affects cats, please visit this page in the petMD health library.
Symptoms in dogs are rarely seen but may include:
A dog may be infected by eating raw meat contaminated with Sarcocystis organisms.
Occasionally, Sarcocystis organisms can be seen in the feces on microscopic fecal examination. However, in most instances, diagnosis is accomplished by finding the organism on histopathology in tissues such as the lungs, liver, kidney, spleen, brain and/or muscle.
More specialized testing such as immunohistochemistry and PCR may be available at some research facilities but are not widely available outside of a research setting.
