Cyclospora cayetanensis can be transmitted through water or food (e.g., basil, raspberries). Clinical manifestations include diarrhea, flulike symptoms, flatulence, and burping. Disease can be self-limited or can persist for >1 month. Diagnosis is made by detection of oocysts (spherical, 8-10 µm) in stool; targeted diagnostic studies must be specifically requested.
Treatment: Cyclosporiasis TMP-SMX (160/800 mg bid for 7-10 days) is effective. Pts with AIDS may need suppressive maintenance therapy to prevent relapses. |
