CD1D and infection: Groups of mice (C57BL/6 WT mice: n = 14, C57BL/6 background Jα18−/− mice: n = 9, and C57BL/6 background CD1d−/− mice: n = 10) were intravaginally infected with C. muridarum, and vaginal shedding of live organisms was monitored throughout the infection using IFU assay on samples collected via vaginal swabs.
