SUMMARY The natural history of prototype and variant Pneumocystis Corinii populations in several colonies of rats were monitored over time periods ranging from 1 to 4 yean. Karyotypic profiles of organism populations from individual rats were evaluated for the proportion of prototype: variant P. carinii and the number of animals harboring co‐infections were enumerated. Throughout the observation periods: (1) each P. carinii population retained its distinctive karyotype; (2) the proportions of prototype:variant within the lungs fluctuated; and (3) the number of rats co‐infected within a colony varied. These surveys suggest a competition between 2 similarly adapted populations.
