摘　　要：目的通过对北京市密云县腹泻患者便标本监测结果的分析，了解腹泻致病菌的流行特征，为腹泻的防控提供科学依据。方法2014年，以密云县医院和密云县中医院为哨点医院，收集腹泻患者病原学监测和流行病学监测数据，分析腹泻致病菌流行特征。结果共监测腹泻患者330例，分离致病菌44件，分离阳性率为13．3％，其中德尔卑沙门菌3株，都柏林沙门菌9株，鼠伤寒沙门菌8株，副溶血弧菌阳性14件，产毒大肠埃希菌9株，肠黏附性大肠埃希菌1株，志贺菌阳性0件；2014年3—8月主要以沙门菌为主，并于5月达到高峰；副溶血性弧菌主要集中在5—8月检出，于7月达到高峰；阳性病例主要分布在16～25岁年龄组（阳性率为11．1％）和26～54年龄组（阳性率为18．5％）。结论该县在5—8月期间，应针对中青年饮食习惯，加强尤其是副溶血性弧菌和沙门菌引起腹泻疾病的主动监测，且采取更科学有效的防控措施。[Objective] To analyze the detection results of fecal specimens from diarrhea patients in Miyun County of Beijing, understand the epidemic characteristics of diarrhea pathogens, and provide a scientific basis for diarrhea prevention and control. [ Methods ] The data of diarrhea patients were collected from Miyun Hospital and Miyun Hospital of Traditional Chinese Medicine in 2014, to analyze the epidemic characteristics of diarrhea pathogens. [Results] Among 330 diarrhea patients, a total of 44 pathogens were isolated with the positive rate of 13.3%, which included 3 strains of Salmonella Derby, 9 strains of Salmonella Dublin, 8 strains of Salmonella typhimurium, 14 strains of Vibrio parahaemolyticus, 9 strains of Enterotoxigenic Escherichia coli, and 1 strain of Intestinal adhesion Escherichia coli, and Shigella was not found. Salmonella was the dominant strain from March to August 2014, and positive rate reached peak in May. Vibrio parahaemolyticus were mainly found from May to August, and positive rate reached peak in July. The positive cases chiefly detected in 16-25 and 26-54 year-old age group, which the positive rate was 11.1% and 18.5% respectively. [ Conclusion ] It is necessary to strengthen the active surveillance to diarrhea caused by Vibrio parahaemolyticus and Salmonella according to the diet habit of middle-aged youth during the March-August, and carry out more scientific and effective prevention and control measures.
