FIG. 1.
Primary C. muridarum genital tract infection of female IgA+/+ and IgA−/− mice. Depo-Provera-treated mice were infected intravaginally with approximately 50,000 IFUs of C. muridarum elementary bodies. Infection was monitored by swabbing the vaginal vault and enumerating IFUs on HeLa cell monolayers (9). Data are presented as log10 IFUs and represent the means ± standard errors of the means of triplicate determinations of 18 mice per group. IFUs recovered from IgA+/+ and IgA−/− mice were not statistically different at any time point (Student's t test).
