幼女阴道感染的病原学分析

Pathogenic analysis of vaginal infection in girls

目的研究引起幼女阴道感染的病原体种类及感染频率,为临床治疗提供参考。方法选取0.5～7岁阴道炎患儿137例,收集阴道分泌物,涂片观察检查念珠菌、滴虫、线索细胞;并进行培养后检查淋球菌、解脲支原体、人型支原体、衣原体;做普通细菌培养检查大肠埃希菌、金黄葡萄球菌、肺炎链球菌、流感杆菌、变形杆菌、绿脓杆菌等。根据病原体感染情况针对性治疗或对症治疗。结果病原体检出率为37.9%,其中以大肠埃希菌感染最多,占检出病原体的25.0%;其他依次为加德纳菌感染占17.3%,淋球菌感染占11.5%,金黄葡萄球菌感染占9.6%。其他病原体有少量检出。结论幼女阴道感染以非特异性感染为主,在病原体导致的感染中,以大肠埃希菌最多,其次为加德纳菌。根据发病原因针对性治疗是理想的治疗方案。

Objective To survey the pathogens and vaginal infection rate in girls. Methods There 137 girls aged from 0.5 to 7 years old were surveyed. Pathogens of vaginal secretion were examined, Candida, Trichomonas and clue cell were observed by smear, while Neisseria gonorrhoeoe, Ureaplasma urealyticum, Mycoplasma hominis and Trachomatis were detected; Escherichia coli, Staphylococcus aureus,Streptococcus pneumoniae, Hemophilus influenzae, Proteus and Pseudomonas aeruginosa were also detected after culture. Vaginal infections were treated. Results The positive rate of pathogens in girls was 37.96%, Escherichia coli predominated with a positive rate of 25.0%; The positive rates of Gardnerella vaginalis, Neisseria gonorrhoeae and Staphylococcus aureus were 17.3%;, 11.5%, 9.6%, respectively. Other pathogens were detected in a small quantity. Conclusion Non-specific infection is the main cause of vaginal infection in girls, Escherichia coli and Giardnerella vaginalis are the most common pathogens. Specific treatment based on aetiological agent can effectively cure the infection.
