Answer

Toxoplasmosis is caused by infection with the protozoan Toxoplasma gondii, an obligate intracellular parasite. The infection produces a wide range of clinical syndromes in humans, land and sea mammals, and various bird species. T gondii has been recovered from locations throughout the world, except Antarctica (see the image below). (See Etiology and Pathophysiology.)
