我院于1977—1982六年来,从粪便中分离出445株痢疾杆菌进行了逐月统计。其1—12月的发病百分率依次为:5.2、4.0、2.0、4.3、6.3、3.6、15.7、23.116.9、8.8,6.1、4.0。从而说明西宁地区细菌性痢疾的流行规律是一年四季都有不同程员的发生,但主要流行季节是第三季度。分离出痢疾杆菌中福氏菌373株,占83.82％;宋内氏菌53株,占11.91％:史密氏菌17株,占3.82％;鲍氏菌2株,占0.45％。福氏菌始终是我区的主要流行菌群。而且从1978年开始突然上升,一直保持在90％左右。其余各群比例很小,未见志贺氏痢疾菌流行。对373株福氏菌进行了分型鉴定:Ⅰ型153株,占
My courtyard in 1977-1982 six years, isolated from the faeces 445 dysentery bacilli monthly statistics. The incidence of 1-12 months were: 5.2,4.0,2.0,4.3,6.3,3.6,15.7,23.116.9,8.8,6.1,4.0. This shows that the prevalence of bacterial dysentery in Xining area is different throughout the year have occurred, but the main epidemic season is the third quarter. 373 strains of Forsythia suspense isolated from Shigella dysenteriae were isolated, accounting for 83.82%; 53 strains of Neisseria gonorrhoeae, accounting for 11.91%; 17 strains of Sagens bacteria accounting for 3.82%; 2 strains of Pasteurella, accounting for 0.45%. Forsythia is always the main epidemic flora in our district. And since 1978 a sudden rise, has remained at about 90%. The proportion of the remaining groups is small, no Shigella dysenteriae prevalence. 373 strains of Forsythia were identified by typing: type Ⅰ 153 strains, accounting for
