Tyzzeria (tī-zē'rē-ă), A genus of coccidia (family Eimeriidae) in which the oocyst contains eight naked sporozoites. Important species areTyzzeria anseris, a relatively nonpathogenic species found in the small intestine of domestic and wild geese, whistling swans, and certain wild ducks,...
A new species of coccidium, Tyzzeria chalcides, is described from the ocellated skink, Chalcides ocellatus, from Egypt. Meronts occur in the epithelial cells of the bile ducts and gamonts within the epithelial cells of the gall bladder. Fully sporulated oocysts are cylindrical (L/W ratio ...
