Toxoplasma gondii is a widely distributed protozoan that is found in multiple animal species. Human infection is common, and may result in lifelong persistence of the organism. Initial infection is usually asymptomatic but can result in a syndrome of fever, lymphadenopathy, and splenomegaly closely resembling infectious mononucleosis. Neurotoxoplasmosis is largely limited to immunocompromised individuals, in particular patients with HIV.
