Cyclospora
Cyclospora is a genus of apicomplexan parasites. It includes the species "Cyclospora cayetanensis", the causative agent of cyclosporiasis. Members of "Cyclospora" are characterized as having oocysts with two sporocysts, each containing two sporozoites. Species. Several "Cyclospora" species have been described in various mammals including: A smaller number of species have been described from reptiles, arthropods, and snakes: Taxonomy and evolution. "Cyclospora" are eukaryotes in the phylum Apicomplexa. Within the Apicomplexa, "Cyclospora" belong to the sub-class Coccidia and family Eimeriidae. Taxonomy of the coccidia is based upon morphological descriptions of observed parasites, and therefore does not always reflect evolutionary  relationships. Genetic studies of the well-conserved SSU rRNA from various specimens has suggested that parasites in "Cyclospora" may be more closely related to some species of "Eimeria" that infect birds than the rest of the genus "Eimeria" is. Relationships among various coccidia estimated for SSU rRNA sequences are shown in the cladogram below: History. The genus "Cyclospora" was created in 1881 to describe a parasite found in a millipede of the genus "Glomeris".
