AETIOLOGY

Toxoplasma gondii is an obligate intracellular coccidian parasite belonging to the Family Sarcocystidae within the Phylum Apicomplexa and is the causative agent of toxo­plasmosis. Felids are the only known definitive hosts (DH) and all endothermic vertebrates are thought to be susceptible to infection and capable of acting as interme­diate hosts (IH).
