【摘要】：目的分析西安地区儿童细菌性腹泻病原菌谱及其流行特征,为制定防治措施提供参考依据。方法对西安地区2004-2016年14岁以下儿童中感染性腹泻患儿的粪便样本进行细菌分离培养鉴定,分析病原菌的分布特征及其变迁情况。结果共采集腹泻儿童粪便标本2 027份,检出阳性标本173份,检出率8.53%;包括志贺菌96株(55.49%),沙门氏菌51株(29.48%),肠致病性大肠杆菌20株(11.56%),副溶血性弧菌5株(2.89%),O157:H7肠出血性大肠杆菌1株(0.58%)。志贺菌属中福氏志贺菌为优势菌型(55株,57.29%),其次是宋内志贺菌(29株,30.21%);福氏志贺菌构成比逐渐下降,宋内志贺菌构成比逐渐上升。结论西安地区14岁以下儿童细菌性腹泻病原菌以志贺菌为主,沙门氏菌的检出比例逐渐增高。要注意菌型的变迁并加强副溶血性弧菌和肠出血性大肠杆菌的主动监测。
[Abstract]:Objective to analyze the pathogenic spectrum and epidemic characteristics of bacterial diarrhea in children in Xi'an. Methods fecal samples from children under 14 years of age in Xi'an from 2004 to 2016 were isolated and identified by bacterial culture. Results 2027 fecal specimens of children with diarrhea were collected and 173 positive samples were detected. The detection rate was 8.53: including 96 strains of Shigella, 51 strains of Salmonella, 20 strains of enteropathogenic Escherichia coli, and 5 strains of Vibrio parahaemolyticus, one strain of Enterohemorrhagic Escherichia coli, one strain of Escherichia coli, one strain of Shigella spp., 55 strains of Shigella flexneri, 55 strains of Shigella flexneri and 57.29%, followed by Vibrio parahaemolyticus. The composition ratio of Shigella flexneri to Shigella flexneri decreased gradually. Conclusion the pathogenic bacteria of bacterial diarrhea in children under 14 years old in Xi'an are mainly Shigella. The detection rate of Salmonella increased gradually. We should pay attention to the changes of bacterial types and strengthen the active monitoring of Vibrio parahaemolyticus and Enterohemorrhagic Escherichia coli.
