Abstract
Mice infected in the genital tract with the Chlamydia trachomatis agent of mouse pneumonitis were treated with monoclonal rat anti-gamma interferon (anti-IFN-gamma) antibody to determine whether IFN-gamma participated in the resolution of the infection. In two experiments, anti-IFN-gamma antibody treatment resulted in significantly prolonged infections. In support of these data, passive administration of recombinant IFN-gamma to chronically infected nu/nu mice was able to bring about resolution of the infection in some animals.
