FIG. 1.

Chlamydial clearance from the genital tracts of untreated or oxytetracycline-treated female mice. Groups of 10 mice were infected intravaginally with chlamydiae. One group was injected subcutaneously with oxytetracycline (1.2 mg/mouse) on the day of challenge and at 2-day intervals for the next 14 days, and the other group was not treated. Mice were cultured at different time points postinfection, and the numbers of infectious organisms shed from the cervicovagina were determined by calculating recoverable IFUs on monolayers of HeLa 229 cells. The values are means ± the standard errors of the means.
