Fig. 4

The compositional profiles of lactobacillus genus (including 10 known lactobacillus species, the unknown ones were all ascribed to a species named lactobacillus Other) in 4 grouping schemes (participants were grouped based on infections, menstrual cycle, childbearing history and infections & with or without gestation, respectively). The average relative abundances (%) in the total 111 women were shown in parenthesis after each species. Each bar represents the compositional profile of lactobacillus species averaged within each group with the average relative abundances (%) of the 2 most abundant species (lactobacillus iners and lactobacillus helveticus) were shown
