Diversity of Sarcocystis Parasites in The Members of Family Mustelidae in Lithuania Protozoan parasites of genus Sarcocystis are characterised by two host life cycle. Sarcocysts are formed in muscles of intermediate hosts, while sporocysts develop in the intestines of definitive host. Some Sarcocyst...
