我们于1984年7～10月收集了肠道门诊385人份腹泻标本进行了致腹泻病原菌的分离鉴定。其中检查出致腹泻病原菌99株,阳性检出率为25.7%。99株致病菌中志贺氏菌为主,有83株,占83.8%;其次为空肠弯曲菌7株(7.1%),侵袭性大肠杆菌4株(4.0%);致病性大肠杆菌3株(3%);不凝集孤菌、沙门氏茵各1株(各1%)。志贺氏菌属中又以B 群占绝对优势(61.4%,51/83);其次为A 群(28.9%,24/83);其中以志贺氏Ⅰ型为多见(87.5%,21/24);D 群为7.2%(6/83);分离到2株C 群,分别为5型及9型。对分离出的51株B 群菌株进行了血清学分型,其中以3a
From July to October of 1984, we collected 385 diarrhea samples from enteric clinics for the isolation and identification of pathogenic diarrhea pathogens. Among them, 99 strains of pathogens causing diarrhea were detected, the positive rate was 25.7%. Among the 99 strains, Shigella was the most common, 83 (83.8%), followed by 7 strains of Campylobacter jejuni (7.1%), 4 strains of Escherichia coli (4.0%), 3 strains of pathogenic Escherichia coli Strain (3%); no coagulation of bacteria, Salmonella each one (1% each). The group B again took the absolute advantage (61.4%, 51/83), followed by group A (28.9%, 24/83), of which Shigella type I was the most common (87.5%, 21 / 24); group D was 7.2% (6/83); two groups C were isolated, which were type 5 and type 9, respectively. Serotypes of 51 isolates of group B were isolated, with 3a
