Dactylosoma Piperis
''Dactylosoma'' is a genus of parasitic Alveolata, alveolates of the phylum Apicomplexa. Species in this genus have two hosts in their life cycle: the vertebrate host is a fish or amphibian (possibly also reptiles) and the invertebrate host is a glossiphoniid leech (''Glossiphoniidae''). Taxonomy This genus was described by Labbé in 1894. The type species is ''Dactylosoma ranarum''. Description Protozoal merogony, Merogony: Schizonts in this genus produce 6 to 16 merozoites by simultaneous exogenous budding. These typically are found in a fan shaped arrangement. This occurs within the erythrocytes. Secondary merogony produces 6 smaller merozoites that are destined to become intraerythrocytic gamonts. Gametogony: The gametocytes are larger, elongated forms derived from some of the merozoites. Oocysts are formed after fertilization in the leech intestine. 30 or more sporozoites are produced by exogenous budding directly in the cytoplasm of the intestinal epithelial cells. No ...
