1 Class : Sporozoa Family : Toxoplasmatidae Genus : Toxoplasma Species : T.gondii This organism is discovered in small African rodents. Disease : Toxoplasmosis and is a zoonotic disease between human and animals.

2 Not : toxo is the arch and plasma is the form. Final host : Cat and all felids. the domestic cat is the most important for this disease. Intermediate host : man, house mice, all domestic animals and birds. Morphology : There are five main stages in the life cycle of T.gondii. although all five stages occur in cats, only two stages are found in man, other mammals and birds.

3 Oocyst:-The sporulated oocyst have two sporocyst with four sporozoites. Trophozoite (Tachyzoite) : Banana in shape or cresentic in shape 4-8µ in length, 2-3µ in breadth and one end more pointed than other, reddish spherical or ovaidal nucleus in shape and usually nearer the blunt end of the parasite. Electron microscope reveal a complex organelles, the toxonemes located at the pointed end (5-8) in number. these toxonemes support the active motility of the organism and it is ability to penetrate the cell.

4 Bradyzoite (cystozoite) : an encysted form (tissue cyst) and similar to tachyzoite, multiply slowly, affect muscle, brain, heart, liver and lung and sensitive to stomach secretion. Life cycle :- indirect, have intermediate host. Main symptom :- hydrocephalus and abortion.
