Abstract: Symptomatic and asymptomatic infections by Toxoplasma and Sarcocystis have been recognized for many years, but it has been only within the last few years that the life-cycles and natural means of perpetuation of same of these species have been worked out. The initial breakthrough resulted from the astute observation of Hutchison (1965) who demonstrated a resistant form of Toxoplasma in cat faeces. Hutchison and coworkers and other groups in ths United States and elsewhere later demonstrated that Toxoplasma cysts on ingestion by susceptible cats went through a typical coccidial cycle in the epithelium of the small intestine. Following on these observations workers in Germany, followed by others in the U.S.A. and Australia, have demonstrated a similar intestinal cycle for several members of the genus Sarcocystis, in several species of meat-eating animals…
