    Abstract:
    OBJECTIVE: To identify and analyze the species of vaginal lactobacilli between patients with bacterial vaginosis (BV) and healthy women at childbearing age in Inner Mongolia. METHODS: From Jun. 2008 to Dec. 2008, 203 Mongolian healthy women, 74 Han healthy women and 102 Mongolian patients with BV from 3 pastoral areas were enrolled in this study. Isolation and culture of lactobacilli from vaginal wall were performed by modified culture medium. DNA of lactobacilli were extracted and sequenced. H₂O₂ were detected by TMB-HRP-MRS. RESULTS: (1) The rate of lactobacilli identification were 76.8% (156/203) in Mongolian healthy women and 21.6% (22/102) in Mongolian patients with BV, which reached statistical difference (P < 0.01). Lactobacilli identification in Han healthy women [82.4% (61/74)] did not show significant difference with that of Mongolian healthy women (P > 0.05). (2) The total of 193 strains and 11 species of Lactobacillus were detected in 203 Mongolian healthy women. Meanwhile, 22 strains and 4 species of Lactobacillus were found in 102 Mongolian BV cases. (3) The rate of H₂O₂ generating Lactobacilli was 27.3% (6/22) in Mongolian BV patients and 75.7% (56/74) in Mongolian healthy women, which showed statistical difference (P < 0.05). CONCLUSIONS: The rate of Lactobacillus was not related with the race of women in pastoral area in Inner Mongolian. The amount of lactobacilli and H₂O₂ generating Lactobacilli in the vagina of BV patients was remarkably lower than those of healthy women at childbearing age.
