FIG. 2.

Course of infection as assessed by quantitation of viable C. trachomatis chlamydia shed from the urogenital tract. C. trachomatis MoPn was isolated from cervical-vaginal swabs collected at 4, 7, 10, and 14 days and every 7 days thereafter through day 56. Each data point represents the mean and standard deviation of IFU enumerated in HeLa 229 cultures of swabs from culture-positive mice. Overall, a significantly lower IFU count was observed when the main effects of treatment group and time were compared (P = <0.0001, two-factor ANOVA). The asterisks designate significant differences in the quantitative recovery of viable MoPn chlamydia at the indicated time points postinfection (two-tailed t test).
