title: Genetic diversity of Pneumocystis carinii isolated from human immunodeficiency virus-positive patients in Turin, Italy.
abstract: By DNA sequence analysis we identified two new strain types and five novel sporadic variations among 25 isolates of Pneumocystis carinii f. sp. hominis obtained from 19 human immunodeficiency virus-positive patients. Of these, 13 were infected with a single strain and 6 were coinfected. Fifteen different combination types were identified among the 18 strains for which complete molecular typing was accomplished.
