Genera enrichment changes across pregnancy stages between strains. Relative abundance in Coprococcus (A), relative abundance in Lactobacillus (B), relative abundance in Prevotella (C), relative abundance in Ruminococcus (D), relative abundance in Helicobacter genus (E), and relative abundance in Streptococcus genus (F). Pink bars represent virgin SD; green bars represent pregnant SD; blue bars represent virgin Dahl S; and purple bars represent pregnant Dahl S. *P < 0.05 vs. gestation stage matched virgin controls. #P < 0.05 vs. baseline virgin SD. n = 6 or 10 female rats. Dahl S, Dahl salt-sensitive; SD, Sprague Dawley.
