Figure 9b. Heat map of the vaginal microbiome by genus. Pregnant and nonpregnant women are marked in red and blue, respectively. Lactobacillus and Gardnerella are circled in red and blue, respectively. Similar to the endometrial microbiome, Lactobacillus spp. is more common in pregnant women, whereas other bacteria (e.g., Gardnerella) are more common in nonpregnant women.
