目的调查海淀区临床细菌性痢疾中确诊菌痢菌型、多病源特征、流行因素、发病特点,为2008年的奥运会肠道传染病预防控制提供充分详细的科学数据。方法对临床诊断为菌痢患者的粪便进行多病原检测,按《细菌性痢疾诊断标准》(GB16002-1995)方法进行,并进行病例流行病学调查。结果临床诊断菌痢的207份粪便标本中,检出致病菌32株,检出率为15.46%,其中志贺菌属13株,检出率6.28%(福氏F4志贺菌2株,宋内志贺菌11株);其他致病菌19株,检出率9.18%。确诊菌痢女性多于男性,与临床性别比存在很大差异;检出数最多为20岁组,检出率最高为30岁组;职业以干部职员、学生为主;工作单位以公司、国家机关为主;危险食品是凉拌菜、生蔬果;外出就餐次数越多,患病的危险性也越大。结论2007年海淀区已成为宋内志贺菌流行为主的地区,临床菌痢中至少有9.18%诊断错误,造成菌痢发病率虚高的假象。干部职员、学生、20岁年龄组为重点防控人群。应进一步加强各种餐饮企业的监督管理,减少致病菌对食品的污染。
Objective To investigate the clinical diagnosis of bacillary dysentery in Haidian district, clinical characteristics of dysentery, multi-source characteristics, epidemic factors and incidence characteristics for the prevention and control of intestinal infectious diseases in 2008 to provide full and detailed scientific data. Methods Multiple pathogenicity tests were performed on the stool samples of patients with clinical diagnosis of bacillary dysentery. The diagnosis was made according to the diagnostic criteria of bacillary dysentery (GB16002-1995) and the case epidemiology was investigated. Results Of the 207 stool specimens clinically diagnosed for bacillary dysentery, 32 strains of pathogens were detected, the detection rate was 15.46%, including 13 strains of Shigella, the detection rate was 6.28% (2 strains of F4 Shigella flexneri, 11 Shigella sonnei); 19 other pathogens, the detection rate of 9.18%. The diagnosis of bacillary dysentery more than men, there is a big difference with the clinical sex ratio; detection of up to 20-year-old group, the highest detection rate of 30-year-old group; professional cadres and students; students to work units to companies, countries Organ-based; dangerous food is cold vegetables, raw fruits and vegetables; eating more times, the greater the risk of illness. Conclusion Haidian District in 2007 has become the main epidemic of Shigella sonnei in clinical bacillary dysentery in at least 9.18% of the diagnostic errors, resulting in the illusion of false dysentery incidence rate. Cadres, students, 20-year-old age group as a key prevention and control of the crowd. Should further strengthen the supervision and management of various catering enterprises to reduce the pollution of pathogens on food.
