FIG 6.

Gross pathology of murine genital tracts infected with C. muridarum Nigg3 mutant clones. (A) Representative gross pathology images of whole genital tracts harvested at 56 dpi. Left and right oviducts and ovaries are amplified for detail. White arrows indicate hydrosalpinges. (B) Incidence of hydrosalpinx at 56 dpi (*, P < 0.05; ***, P < 0.001, by Fisher's exact test against the results for the control organism; n = 5 per group). (C) Severity of hydrosalpinx at 56 dpi (P = 0.021, by a Kruskal-Wallis test; *, P < 0.05, by Dunn's multiple-comparison test against the results for the control organism). Both individual bilateral scores (black dots) and medians (gray bars) are shown.
