摘要
Sarcocystis has an obligatory two-host life cycle. An intennediate host acquires infection by ingesting sporocysts or oocysts from the faeces of an infected definitive host. A definitive host becomes infected with Sarcocystis by eating the sarcocyst-infected flesh of the intermediate host. For Sarcocystis suihominis, humans, chimpanzees (Pan troglodytes), rhesus monkeys (Macaca mulatta) and cynomolgus monkeys (Macaca irus) are definitive hosts and the pig is its intermediate host. The infection situation of humans in other regions of the world is unknown. Zuo et al. (1983) first reported two cases with natural S. suihominis infection in Yunnan Province, China1.
