CP and congenital rubella syndrome: By analysis of relative abundances at phylum levels in female mice, Bacteroidetes and Firmicutes were the main components of microbiota (Figure 6A), showing significant change in the CRS group after experiment (Bacteroidetes, p = 0.025; Firmicutes, p = 0.012), but there was no significant change in the CON or CP groups (Figure 6C,D).
