目的:为了解细菌性痢疾(简称菌痢)流行趋势及状况。方法:1997年6月至11月在市30个村31189人进行检测,凡腹泻病人一律在未服抗生素前采集其新鲜粪便于C-B运送培养基中,然后进行痢疾志贺菌属检查。结果:共发现腹泻病人3332人次,发病率为10.68%,其中临床诊断为菌痢526例,发病率为1.69%(男、女发病率分别为1.59%和1.79%,2χ=1.77,P>0.05),病原学确诊发病率为1.48%(男、女发病率分别为1.65%和1.30%,2χ=6.62,P<0.01)。从临床诊断为菌痢、肠炎及其它腹泻病人中分别检出菌痢志贺菌64.83%、3.88%和0.69%,四群均有检出,共发现15个血清型和亚型。结论:在监测点有以下几个特点:流行菌株仍以F2 a存在,但X变种大有后来居上之势;年龄上以50~60岁组发病率最高;<5岁组发病率最低,时间上除7月份发病较多外,其他月份没有明显差别。
Objective: To understand the epidemic trend and status of bacillary dysentery (referred to as bacillary dysentery). Methods: From June to November 1997, 31,189 people in 30 villages of the city were tested. All patients with diarrhea were collected fresh C-B before they took antibiotics and then tested for Shigella dysenteriae. Results: A total of 3332 diarrhea patients were found, with a prevalence of 10.68%. Among them, 526 cases were clinically diagnosed as bacillary dysentery with a morbidity of 1.69% (male and female incidence rates were 1.59% and 1.79% respectively, 2χ = 1.77, P> 0.05 ), The etiological diagnosis of the incidence of 1.48% (male and female incidence rates were 1.65% and 1.30%, 2χ = 6.62, P <0.01). From the clinical diagnosis of bacillary dysentery, enteritis and other diarrhea patients were detected Shigella dysenteriae 64.83%, 3.88% and 0.69%, were detected in four groups were found in 15 serotypes and subtypes. Conclusion: There are several characteristics in the monitoring point: the prevalence of strains still exist in F2a, but the X variant has a great come out of the trend; the age of 50 to 60-year-old group the highest incidence; <5-year-old group the lowest incidence of time Except for the more incidence in July, there was no obvious difference in other months.
