The uterus, cervix, liver, adrenal gland, kidney, lung, and brain were collected 12\u00a0h after injection and transcriptomes were measured using microarrays. Heatmaps and principal component analysis were used for visualization. Differentially expressed genes between groups were assessed using linear models that included interaction terms to determine whether the effect of infection differed with pregnancy status.
