Cyclospora is a genus of apicomplexan parasites. It includes the species Cyclospora cayetanensis , the causative agent of cyclosporiasis . [ 1 ] Members of Cyclospora are characterized as having oocysts with two sporocysts , each containing two sporozoites .
When an oocyst of Cyclospora cayetanensis enters the small intestine, it invades the mucosa, where it incubates for about one week. After incubation, the infected person begins to experience severe watery diarrhea, bloating, fever, stomach cramps, and muscle aches. [citation needed] The parasite particularly affects the jejunum of
Cyclospora cayetanensis is a coccidian parasite that causes a diarrheal disease called cyclosporiasis in humans and possibly in other primates. Originally reported as a novel pathogen of probable coccidian nature in the 1980s [1] and described in the early 1990s, [1] it was virtually unknown in developed countries until awareness increased due to several outbreaks linked with fecally ...

The taxonomy of this group is complex and only partly understood. Two major clades have been identified: the isosporoid coccidia (Toxoplasma, Neospora, Isospora [in part], and Sarcocystis) and a second clade containing Lankesterella, Caryospora and the eimeriid coccidia (Cyclospora, Isospora [in part] and Eimeria). [1]
These can be categorized into three groups; cestodes, nematodes and trematodes.Examples include: Acanthocephala; Ascariasis (roundworms); Cestoda (tapeworms) including: Taenia saginata (human beef tapeworm), Taenia solium (human pork tapeworm), Diphyllobothrium latum (fish tapeworm) and Echinococcosis (hydatid tapeworm)
Human parasites are divided into endoparasites, which cause infection inside the body, and ectoparasites, which cause infection superficially within the skin. The cysts and eggs of endoparasites may be found in feces , which aids in the detection of the parasite in the human host while also providing the means for the parasitic species to exit ...
Isospora is a genus of internal parasites in the subclass Coccidia. [ 1 ] [ 2 ] It is responsible for the condition isosporiasis , which causes acute, non-bloody diarrhoea in immunocompromised individuals.
