摘    要:目的 对内蒙古牧区育龄期健康妇女及细菌性阴道病(BV)患者的阴道乳杆菌种进行鉴定与分析,为阴道微生态治疗提供依据.方法 2008年6至12月,选取内蒙古自治区3个牧区旗县(正镶白旗、达尔罕茂明安联合旗、百灵庙镇)育龄期蒙古族健康妇女203例、汉族健康妇女74例,蒙古族BV妇女102例,采用改良乳杆菌培养基(MRS)对阴道侧壁分泌物中乳杆菌进行分离、培养,提取细菌总DNA,进行核糖体脱氧核糖核酸(16S rDNA)基因序列鉴定,并采用四甲基联苯胺-辣根过氧化物酶-乳杆菌培养基(TMB-HRP-MRS)对乳杆菌进行产H2O2分析.结果 (1)检出率:203例蒙古族健康妇女乳杆菌检出率为76.8%(156/203),蒙古族BV妇女乳杆菌检出率为21.6%(22/102),两者比较,差异有统计学意义(P<0.01);汉族健康妇女乳杆菌检出率为82.4%(61/74),与蒙古族健康妇女比较,差异无统计学意义(P>0.05).(2)阴道乳杆菌鉴定:蒙古族健康妇女阴道分泌物中共检出193株乳杆菌株,共11种,蒙古族BV妇女阴道分泌物中检出22株乳杆菌株,共4种.(3)H2O2阳性乳杆菌的鉴定:对分离出乳杆菌的74例蒙古族健康妇女及22例蒙古族BV妇女进行阴道乳杆菌H2O2实验,其中蒙古族健康妇女阴道H2O2阳性乳杆菌的检出率为75.7%(56/74),蒙古族BV妇女阴道H2O2阳性乳杆菌的检出率为27.3%(6/22),两者比较,差异有统计学意义(P<0.05).结论 内蒙古牧区育龄期健康妇女阴道乳杆菌检出率与种族无明显相关性;BV妇女的阴道乳杆菌及H2O2阳性乳杆菌检出率均较健康妇女明显降低.
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.
