A transtracheally inoculated mouse model of Pneumocystis carinii has been developed using BALB/c mice. The advantage of this strain of mice include that they are widely available, inexpensive, and were not infected with Pneumocystis before inoculation. Inoculated mice that were not treated had a mean infectivity score of 4.1 compared with inoculated mice treated with the effective anti-Pneumocystis drug combination of trimethoprim plus sulfamethoxazole, which had a mean infectivity score of 0.1, an approximately 4 log difference. The inoculated BALB/c mouse provides a model to serve as a valuable addition to rat models currently used, providing a source of organisms from a different host for cross-species comparisons and for studies of drug efficacy for therapy and prophylaxis. The inoculated mouse is especially cost effective and allows testing of compounds in short supply.
