FIG 4.

FTY720 fails to alter Chlamydia induction of hydrosalpinx in the upper genital tracts of CBA/J mice. (a and b) The same two groups of CBA/J mice (n = 10) as described in the Fig. 1 legend were sacrificed for observing the hydrosalpinx on day 56 after intravaginal infection. One gross image of the genital tract tissue is presented from each group, with vagina on the left and oviduct/ovary on the right. Hydrosalpinx was marked with a white arrow. The magnified oviduct/ovary images on the right are marked with the corresponding hydrosalpinx scores. (c) Hydrosalpinx severity scores are plotted. n = 10; data are from two independent experiments.
