Document Summary
It is an intestinal disease due to a parasite (protist). It is a single celled organism that is extremely small, even to microscopes. It is contracted by consuming contaminated food or water typically fresh fruits and vegetables. This particular disease is typically not life threatening. Within healthy immune systems the body can recover but if the disease goes untreated then the symptoms have a high probability of having a relapse. Being left untreated can lead to serious long term medical conditions (https://www. cdc. gov/parasites/cyclosporiasis/) (https://www. cdc. gov/parasites/cyclosporiasis/disease. html) (http://www. foodsafetynews. com/2013/07/publishers-platform-what-is-cyclospora- cayetanensis/#. waevszk-kb8) Life cycle / general biology of the protist: Environmental contamination: the environment must be between 22 c and 32 c in order for sporulation to occur. Sporulation happens for approximately 2 weeks where the sporont undergoes sexual reproduction to make two elongate sporozoites. The oocyst is excreted into the environment (cycle starts over) (https://www. cdc. gov/parasites/cyclosporiasis/biology. html#coccidian) Who is us susceptible to the disease and how is it spread:
