目的:分析感染性腹泻患儿的发病情况及病原分布,探讨引起儿童感染性腹泻的常见病原体。为临床治疗提供参考。方法:回顾性分析2009年1月—2010年12月我院收治的578例感染性腹泻患儿的临床及病原学资料。结果:578例感染性腹泻患儿,1天-3岁345例,(3-6)岁151例,(6-14)岁82例,夏季发病率最高,占29.3%,其次为秋季26.5%,大便培养阳性228例,其中病原菌构成比前3位分别为痢疾杆菌37.7%大肠埃希菌29.8%和肠球菌属14.5%;轮状病毒检测阳性(12.0%)。婴幼儿感染性腹泻以轮状病毒为主要病原。结论:儿童感染性腹泻发病以婴幼儿多见,季节以夏季、秋季为主,病原复杂多种,临床诊治过程中应重视病原学诊断,以合理应用抗菌药物。
Objective: To analyze the incidence and distribution of pathogens in children with infectious diarrhea and to explore the common pathogens causing infectious diarrhea in children. Provide a reference for clinical treatment. Methods: The clinical and etiological data of 578 children with infectious diarrhea admitted to our hospital from January 2009 to December 2010 were retrospectively analyzed. Results: Among 578 cases of infectious diarrhea, 345 cases were from 1 day to 3 years old, 151 cases were (3-6) years old and 82 cases (6-14) years old. The highest incidence was in summer, accounting for 29.3%, followed by 26.5% , Stool culture was positive in 228 cases, of which the pathogens constitute the first three were 37.7% of Shigella dysenteriae Escherichia coli 29.8% and Enterococcus 14.5%; rotavirus positive (12.0%). Infectious diarrhea in infants and young children with rotavirus as the main pathogen. Conclusion: The incidence of infectious diarrhea in children is more common in infants and toddlers. The season is mainly summer and autumn with many complicated pathogens. In the process of clinical diagnosis and treatment, etiological diagnosis should be emphasized in order to rationally use antimicrobial agents.
