When comparing the gross pathology of genital tract tissues collected 80 days after infection among three groups of mice (WT, Jα18−/− mice, and CD1d−/− mice), we observed that 4 out of 28 oviducts from WT mice, 10 out of 18 oviducts from Jα18−/− mice, and 11 out of 20 oviducts from CD1d−/− mice developed hydrosalpinx (Figure 4A). This evidence concerns the gene CD1D and infection.
