Cyclospora in AIDS patients: not always an agent of diarrhoic syndrome.

The present study reports the clinical features of two AIDS patients infected by Cyclospora. According to our observations, Cyclospora in AIDS can be responsible both for gastroenteritis and for asymptomatic infections with spontaneous rapid clearance. In addition, and undiagnosed circulation of this agent in Italy could be hypothesized: neither patient had a past history of foreign travel. These are the first two cases in AIDS described in Italy.
