目的　了解引起小儿阴道炎病原菌状况。方法　取小儿阴道炎首诊患者 (1mo～ 13a)的阴道分泌物 6 6 0份做细菌培养 ,药敏试验使用 K- B纸片扩散法 ,以NCCL S标准为判定标准 ,对各种细菌的分布特征及耐药性进行分析。结果　检出阳性标本 6 10份 (92 .4% ) ,共 2 3种 82 5株细菌 ,有革兰阳性棒状杆菌 19.6 % ,葡萄球菌 14.1% ,大肠埃希菌 13.5 % ,嗜血杆菌 12 .6 % ,真菌 3.6 % ,淋病奈瑟菌2 .4%等 ,检出复数菌 195份 (2 9.5 % )。结论　大肠埃希菌和肠道、呼吸道的常见致病菌是引起小儿阴道炎的主要菌 ,嗜血杆菌、淋病奈瑟菌引起的感染应重视 ,真菌感染多发生于学龄期。嗜血杆菌的耐药情况不同于一般细菌 Objective To understand the status of pediatric vaginitis pathogens. Methods Six hundred and sixty vaginal secretions from the first diagnosis of vaginitis in children (1mo ~ 13a) were taken for bacterial culture. Drug susceptibility test was performed using K-B disk diffusion method and NCCL S standard Distribution characteristics and drug resistance analysis. Results A total of 6 10 positive samples (92.4%) were detected. A total of 23 strains of 82 5 bacteria were detected, including Gram-positive coryneform bacteria 19.6%, Staphylococcus aureus 14.1%, Escherichia coli 13.5% and Haemophilus 12. 6%, 3.6% of fungi, 2.4% of Neisseria gonorrhoeae, etc., and 195 (29.5%) were detected. Conclusion Escherichia coli and intestinal, respiratory pathogens are common cause of vaginitis in children, Haemophilus, Neisseria gonorrhoeae infections should be emphasized, fungal infections occur in school age. Haemophilus resistance is different from the general bacteria
