Toxoplasma gondii

Pronunciation: tok'so-plaz'ma gon'de-i

Definition: An abundant, widespread sporozoan species (family Toxoplasmatidae) that is an intracellular, non–host-specific parasite in a great variety of vertebrates. It develops its sexual cycle, leading to oocyst production, exclusively in cats and other felids; proliferative stages (tachyzoites) and tissue cysts (containing bradyzoites) develop in a wide variety of animal species that acquire the infection from ingestion of oocysts, tissue cysts from infected meat, organ transplantation or by transplacental migration, leading to infection in utero.

[G. toxon, bow or arc, + plasma, anything formed]
