Interpretive summary: Toxoplasma gondii is a single-celled parasite of all warm-blooded hosts worldwide. It causes mental retardation and loss of vision in children, and abortion in livestock. Cats are the main reservoir of T. gondii because they are the only hosts that can excrete the resistant stage (oocyst) of the parasite in the feces. Humans become infected by eating under cooked meat from infected animals and food and water contaminated with oocysts. Little is known of the circulation of Toxoplasma in wildlife. The authors report first isolation of Toxoplasma from a wild cougar in Mexico, indicating that wild cats can spread Toxoplasma in urban environment. The results will be of interest to biologists, parasitologists, and public health workers.
