The figure 1 describes the life cycle of Toxoplasma gondii: The unsporulated oocysts are shed in cat feces. Oocysts sporulate in the environment and become infective. The sporulated oocysts infect humans through contaiminated food, water and soil. Sporulated oocysts infect animals or birds through contaminated feed, water and soil. Sporulated oocysts infect humans through containminated food, water and soil. The intermediary hosts include pigs and many other mammals such as sheep, goats rats and birds. Intermediate hosts infect each other through tissue cysts. Humans are infected through cysts in tissues of intermediate hosts (raw and undercooked meat). Fetus are infected through tachyzoites transmitted through the placenta. Cats infected through cysts in tissue of intermediate hosts.
