'' Calyptospora'' is a genus of parasitic protozoa in the phylum Apicomplexa. This genus and family was created in 1984 for the species ''Eimeria funduli'' because of morphological differences in the sporocyst suggested that it was not a typical member of the genus ''Eimeria''.〔Overstreet RM, Hawkins WE, Fournie JW (1984) The Coccidian Genus ''Calyptospora'' n. g. and Family ''Calyptosporidae'' n. fam. (Apicomplexa), with members infecting primarily fishes. J Euk Micro 31 (2) 332–339 〕 The type species is ''Calyptospora funduli''. ==Life cycle== These parasites infect the livers of their fish hosts which they appear to reach via the gasterintestinal tract. They have an obligatory intermediate host - usually a shrimp - in which they infect the entrocytes of the shrimp gut. The life cycle appears to be as follows: infected fish excrete the parasites from their gasterointestinal tract into which they are secreted with the bile. An intermediate host such as a shrimp ingests the parasite which then decysts and infects the gut wall of the shrimp. The shrimp is then ingested by a fish whereupon the parasite is released and invades the fish's gut wall. The parasites then travel via the blood stream to the liver wherein they mature. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Calyptospora」の詳細全文を読む スポンサード リンク
