104例急性散发腹泻病例病原学分析

Analysis of etiology and epidemiology in 104 sporadic acute diarrhea cases

目的:了解北京市宣武区春季就诊的急性散发腹泻病例中病原感染分布现状,为制定相关防治策略提供依据。方法:以北京市宣武医院就诊的腹泻病例作为监测对象,留取便标本进行霍乱弧菌、沙门菌、志贺菌、副溶血弧菌、致泻大肠杆菌和诺如病毒、轮状病毒检测及分析。结果:共调查并检测腹泻病例104例,总阳性率38.5%,细菌培养阳性率21.2%,病毒检测阳性率为20.2%,有3例患者便检结果细菌、病毒皆为阳性。结论:急性散发腹泻病原类型复杂多样,应进行必要的病原学监测及研究,以进一步明确感染性腹泻的流行特征。

Objective：To investigate the pathology, epidemiology and the clinical characteristic of sporadic acute diarrhea cases in Xuanwu district of Beijing. Methods： Diarrhea cases in Xuanwu hospital were selected as monitoring objects, and the stool specimens were collected from these cases for detection and analysis of vibrio cholerae, salmonella, shigella, vibrio parahaemolyticus, diarrheagenic escherichia coli, itorovirus and rotavirus. Results： 104 diarrhea cases were detected with the total positive rate of 38.5%, bacterial culture positive rate of 21.2% and vi- rus positive rate of 20.2% , and 3 cases were positive for both bacteria and virus. Conclusion ： Sporadic acute diarrhea cases were various, which should be strengthened pathogenic monitoring to further show the epidemic characteristics of infectious diarrhea.
