Comparison of vaginal lactobacillus species between the women of mongol nationality with bacterial vaginosis and healthy women of mongol nationality

Objective:To explore the differences of vaginal lactobacillus species distribution and producing H2O2 ability between the women of mongol nationality with bacterial vaginosis and healthy women of mongol nationality. Methods:102 women of mongol nationality with bacterial vaginosis were selected as case group,98 normal women of mongol nationality were selected as control group,the distribution of vaginal lactobacillus species was examined;the producing H2O2 ability of vaginal lactobacillus was detected,the vaginal lactobacillus species were determined. Results:The detection rates of lactobacillus in the two groups were 21.6%(22/102) and 75.5%(74/98),respectively,there was significant difference between the two groups(χ2=21.016,P=0.001).There was no significant difference in distribution of lactobacillus species between the two groups(P0.05).Lactobacillus crispatus,lactobacillus gasseri,lactobacillus acidophilus and lactobacillus casei were the main species;the isolation rates of lactobacillus with positive H2O2 in the two groups were 27.3%(6/22) and 75.7%(56/74),respectively,there was significant difference between the two groups(χ2=4.528,P0.05). Conclusion:Compared with healthy women of mongol nationality,the detection rate of vaginal lactobacillus in the women of mongol nationality with bacterial vaginosis decreases significantly;the isolation rate of vaginal lactobacillus producing H2O2 and the total ability of producing H2O2 decrease significantly;the distributions of vaginal lactobacillus species of the women of mongol nationality with bacterial vaginosis and healthy women of mongol nationality are similar.
