目的了解北京市朝阳区食源性腹泻病例监测病原构成,提高聚集性病例的识别能力,为食源性疾病治疗、预防与控制提供指导。方法采集北京市朝阳区哨点医院食源性腹泻病例粪便标本,并对所采标本进行微生物学检测,分析记录资料。结果 1 548份病例粪便标本中,有164例标本检出食源性致病菌,病原菌检出率为10.59%;其中检出沙门菌71株,志贺菌5株,副溶血性弧菌11株,5种致泻性大肠埃希菌77株。病原菌检出率不同年份(χ~2=6.665,P<0.05)、不同季节(夏秋和冬春比较χ~2=23.844,P<0.01)、不同年龄段(χ~2=11.955,P<0.01)差异均有统计学意义。结论 2013—2015年北京市朝阳区食源性腹泻病例在8种常见食源性致病菌中以沙门菌为主。
Objective To understand the pathogenic constitution of food-borne diarrhea cases in Chaoyang District, Beijing and to improve the identification ability of aggregated cases and provide guidance for the treatment, prevention and control of food-borne diseases. Methods Stool samples of food-borne diarrhea were collected from sentinel hospital in Chaoyang District, Beijing. Microbiological tests were performed on the collected samples, and the recorded data were analyzed. Results Among 5484 cases of stool samples, 164 samples detected food-borne pathogens, and the detection rate of pathogenic bacteria was 10.59%. Among them, 71 strains of Salmonella, 5 strains of Shigella, 11 strains of Vibrio parahaemolyticus Strain, five kinds of diarrhea Escherichia coli 77. The detection rate of pathogen was different in different years (χ ~ 2 = 6.665, P <0.05), and in different seasons (χ ~ 2 = 23.844, P <0.01 in summer and autumn and winter and spring) ) Differences were statistically significant. Conclusions In 2013-2015, food-borne diarrhea cases in Chaoyang District of Beijing were dominated by Salmonella in eight common food-borne pathogens.
