==Background==
*one celled microscopic parasite that causes intestinal infection
*fecal-oral transmission
*endemic in tropical and subtropical regions

==Signs/Symptoms==
*watery (sometimes explosive) diarrhea, loss of appetite, weight loss, stomach cramps/pain, bloating, increased flatus, nausea, and fatigue
*can last days to over a month
*In immunocompromised hosts, cyclospora may cause severe, intractable, voluminous diarrhea resembling cryptosporidiosis. Extraintestinal disease in patients with AIDS may include cholecystitis and disseminated infection.

==Diagnosis==
*stool O&P
*Detection is facilitated by staining stool samples with modified acid-fast stain or modified safranin stain. Multiple (≥ 3) stool specimens may be needed because cyst secretion may be intermittent (2)

==Management==
*Bactrim: 160 mg TMP and 800 mg SMX po bid for 7 to 10 days for cyclosporiasis or for 10 days. Children are given 5 mg/kg TMP and 25 mg/kg SMX po bid for the same number of days.
*Immunocompromised patients may require higher doses and longer duration of treatment, and treatment of acute infection is usually followed by long-term suppressive therapy
