Does pneumocystis carinii occur in Kenya?

Abstract

An experiment was carried out exposing immuno-suppressed mice to the atmosphere to determine if transmission of Pneumocystis carinii occured in Kenya. Mice were killed at weekly intervals for four months and the lungs examined histologically for the presence of these parasites. None of the mice contracted even light infections and this, together with the lack of clinical evidence of this disease in immunosuppressed or neonatal cases, suggests that this parasite does not occur in Kenya. Possible reasons for this are discussed.
