摘要
目的分析感染性腹泻病原菌的构成比和流行病学特征,为感染性腹泻的预防和治疗提供科学依据。方法于2013年1月1日~2015年12月31日肠道门诊收治的感染性腹泻患者中随机抽取600例作为研究的对象,对这600例感染性腹泻患者的临床资料进行总结分析,对患者进行病原菌监测,对病原菌的菌种进行鉴定,采用药敏试验对其耐药性进行检测,并分析感染性腹泻的发病特点。结果 600例感染性腹泻患者经病原菌培养,共分离出285株病原菌,包括276株细菌菌株、9株病毒菌株,菌种占比从高至低排列依次为副溶血性弧菌、沙门菌、大肠埃希菌、鲍氏志贺菌、痢疾志贺菌、轮状病毒、霍乱弧菌。药敏试验结果显示,副溶血性弧菌、沙门菌、大肠埃希菌等细菌性腹泻的主要致病菌对氨苄西林的敏感性普遍较低,而喹诺酮类药物对细菌性腹泻的致病菌均较为敏感。发病特点:发病季节以夏季为主,所占比例为63.67%;副溶血性弧菌感染多见于21~40岁人群,沙门菌感染多见于婴幼儿。结论感染性腹泻的主要病原菌为副溶血性弧菌、沙门菌以及大肠埃希菌,卫生部门应在夏季加强感染性腹泻的安全教育和食品卫生监督。
Objective To analyze pathogenic bacteria composition and epidemiological characteristics of infectious diarrhea in Kangping from 2013 to 2015,and to provide scientific evidence for the prevention and treatment of infectious diarrhea. Methods During the period from January 1,2013 to December 31,2015,a total 600 cases with infectious diarrhea in Kangping County People＇ s Hospital were randomly selected the study subjects. The clinical data of these patients were retrospectively analyzed. Pathogenic bacteria were detected in the patients,the bacteria strains were identified,and their drug resistance was tested by drug sensitivity test,and the characteristics of infectious diarrhea were analyzed. Results In 600 cases with infectious diarrhea by culture of pathogenic bacteria,a total of 285 strains of pathogenic bacteria were isolated,including 276 strains of bacterial strains,9 strains of virus strains; strain composition ratio is arranged from high to low in order to Deputy Hemolysis Vibrio,Salmonella,Escherichia coli,Shigella boydii,Shigella dysenteriae,rotavirus virus,cholera vibrio. Drug sensitivity test showed that deputy hemolysis Vibrio,Salmonella,Escherichia coli,and so on（ main pathogenic bacteria causing bacterial diarrhea） were less sensitive to ampicillin,and these pathogenic bacteria are more sensitive to quinolones. Epidemiological characteristics： infectious diarrhea mainly occurred in the summer,the proportion of 63. 67%; Vibrio parahaemolyticus infection is more common in the population aged 21- 40,Salmonella infection in infants. Conclusions The main pathogens of infectious diarrhea is Vibrio parahaemolyticus,Salmonella and Escherichia coli,health departments in Kangping county should strengthen the safety education and food hygiene supervision of infectious diarrhea in summer.
