FIG. 1.
Inability of Th2-MoPn to resolve a chlamydial genital infection in nude mice. Clones Th2-MoPn and Th1-MoPn and cell line KLH-1 (1 × 107 cells) were transferred intravenously via the retroorbital plexus into nude mice that had been infected 10 days previously. The infection was monitored by determining the number of IFU of MoPn obtained with cervical-vaginal swabs. Animals were swabbed every 10th day for 80 days following transfer. The values are means ± standard errors of the means for 5 (KLH-1), 10 (Th2-MoPn), or 15 (Th1-MoPn and no cells) mice in two separate experiments.
