Figure 1. Abundance of Lactobacillus spp. and pathological bacteria in pregnant and nonpregnant women.

Pregnant patient numbers 1,7,9,12,15 and nonpregnant patient numbers 1,3,7,8,11 were diagnosed with chronic endometritis by hysteroscopy and treated with antibiotics. Several pregnant women had a high abundance of Lactobacillus spp. in both the endometrium and vagina, and many nonpregnant women had a high abundance of pathological bacteria.
