Immunodeficient animals are in demand in current biomedical research, and they contribute to medical progress. In Pneumocystis infections, a specific histological diagnostic tool may be immunochemistry (IC). However, it was recently reported that the antibody (3F6) was not suitable for detecting Pneumocystis in rats. We purchased another antibody [PNC007] from a commercial source for IC. We could detect positive signals at identical locations with IC and Toluidine blue O in lungs of infected rats. These results corresponded to the results obtained with PCR. We should study the relationship between unexpected positive signals seen in IC and trophic forms in lungs of infected rats. We could clinically diagnose pneumonia caused by Pneumocystis carinii with the diagnostic method we developed.
