Dactylosoma
''Dactylosoma'' is a genus of parasitic alveolates of the phylum Apicomplexia. 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 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 oocyst wall is formed. Spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Protozoal Merogony
Apicomplexans, a group of intracellular parasites, have life cycle stages that allow them to survive the wide variety of environments they are exposed to during their complex life cycle. Each stage in the life cycle of an apicomplexan organism is typified by a ''cellular variety'' with a distinct morphology and biochemistry. Not all apicomplexa develop all the following cellular varieties and division methods. This presentation is intended as an outline of a hypothetical generalised apicomplexan organism. Methods of asexual replication Apicomplexans (sporozoans) replicate via ways of multiple fission (also known as schizogony). These ways include , and , although the latter is sometimes referred to as schizogony, despite its general meaning. Merogony is an asexually reproductive process of apicomplexa. After infecting a host cell, a trophozoite ( see glossary below) increases in size while repeatedly replicating its nucleus and other organelles. During this process, the orga ...
