摘　　要：目的探讨北京市朝阳区2003～2006年细菌性痢疾发病的流行特征，掌握其流行规律，为制定预防控制对策和措施提供科学依据。方法采用描述流行病学方法，对朝阳区2003～2006年临床诊断菌痢的资料进行分析。结果朝阳区2003～2006年共有临床诊断菌痢病例29722例，年平均发病率为296／10万。发病有明显的季节性，6～9月份共有病例20268例，占病例总数的68．19％。高发年龄为10岁以下年龄组。603例临床诊断菌痢病例进行了粪便细菌培养，阳性89份，阳性率为14．76％，其中检出B群福氏志贺氏菌64份，占71．91％，D群宋内志贺氏菌25份。结论通过病原学分型可以看到临床诊断的菌痢病例经过粪便培养，实际检出的阳性率很低，目前我国诊断菌痢的现行标准还有待进一步探讨。Objective To explore the epidemiological features of shigellosis during 2003 to 2006 in Chaoyang District, Beijing, and understand the rules of its incidence to provide scientific basis for formulating strategy and measures of its prevention and control. Methods Distribution of all the cases of bacillary dysentery diagnosed clinically during 2003 to 2006 in Chaoyang District was described and analyzed based on the data collected. Results There were 29 722 cases of bacillary dysentery diagnosed during 2003 to 2006 in Chaoyang District, with an annual incidence of 296 per 100 000 population. There was an obvious seasonality of incidence, 20 268 cases occurred in June to September, accounting for 68.19 percent of the total cases, and there was a peak of incidence in children aged under ten years. Fecal bacillary culture was conducted in 603 cases, with positive results in 89 cases （14.70%）, 64 identified as group B of Shigella flexneri （71.9 % ） and 25 as group D of Shigella sonnei （28.1% ）. Conclusion Low positivity of shigella bacillus was detected by fecal culture in patients with bacillary dysentery clinically diagnosed. Therefore, current diagnostic criteria for bacillary dysentery in China should be explored further.
