To understand the way of reinfection of Pneumocystis carinii we have analyzed the genetic variation at the internal transcribed spacer (ITs) in DNA samples from bronchoalveolar lavage fluid of italian HIV patients who had multiple episodes of P. carinii pneumonia. The presence of the same and/or a new type in both episode suggest the possible occurence of both reactivation of a previously acquired infection and reinfection from an exogenous source. Furthermore the occurence of two different types in the same episode indicate that a mixed infection is common.
