Interpretive Summary: Infection by the protozoan parasite, Toxoplasma gondii is widespread in man and animals. It causes abortion in livestock and mental retardation and loss of vision in congenitally infected children. Most cases of clinical toxoplasmosis in animals are seen in young animals or those with immuno-deficiencies. Scientists at the Beltsville Agricultural Research Center and Cornell University report the first confirmed case of toxoplasmosis in a 13 year old cat concurrently infected with a viral infection (Feline Infectious Peritonitis). These results will be of interest to veterinarians.

Technical Abstract: A 13-year-old, 4-kg, neutered male, Maine Coon cat was presented with ascities. Toxoplasma gondii tachyzoites were seen within neutrophils and macrophages, and free within the abdominal fluid. At necropsy, many abdominal organs were positive for Feline Infectious Peritonitis antigens using immunohistochemical staining. This is apparently the first report of concurrent FIP and toxoplasmosis in a domestic cat.
