Cyclospora cayetanensis

Cyclospora cayetanensis is a unicelluar, coccidian, microscopic parasite which causes cyclosporiasis, an intestinal disease in humans and small to be seen without a microscope. Its full name is Cyclospora cayetanensisa, and it has a life cycle that involves both sexual and asexual reproduction.Cyclosporiasis occurs in many countries, but it seems to be most common in tropical and subtropical regions. In areas where cyclosporiasis has been studied, the risk for infection is seasonal. However, no consistent pattern has been identified regarding the time of year or the environmental conditions, such as temperature or rainfall.

Characteristics
Shape and Size
enteric parasitic protozoa ovoid, 8-10 ¼m in diameter with a 113 nm thick bilayered wall.
Genome Information
Cyclospora cayetanensis isolate KKU 18S ribosomal RNA gene, partial sequence is a enteric parasitic protozoa ( GI:290783686) has a Linear DNA of 294 bp .
Food Source
water, Fruits (strawberries and raspberries) ,Lettuce, Parsley, Cilantro, Blackberries,dill, chives, parsley, green onions, butterhead lettuce, mixed lettuce, red cabbage, white cabbage, carrots, cucumbers, celery and contaminated water
Pathological Factor
It infects the epithelial cells that line the small intestine. The oocyst has a thick bilayered wall, allowing the organism to be environmentally resistant and able to survive until ingestion of a host, and allows the pathogen to survive while traveling through the stomach to get to the small intestine where it wants to be.
