The Serotypes Ideutification of Some Pathogen of Edema of Swine in Qinghai Province

就青海省仔猪水肿病多发区分离鉴定的45株溶血性大肠杆菌进行了血清学定型,结果表明:已鉴定出血清型的菌株33株,占73.3％,12株未定出血清型,占26.7％;其中O810株(22.2％),O251株(2.2％),O101 1株(2.2％),O1383株(6.7％),O1397株(15.5％),O1415株(11.1％),O1496株(13.3％)。O抗原优势菌株分别为:O8、O139、O141、O149,占全部菌数的62.2％。

45 strains Escherichia coli of piglets were separated and ideutified by serological definition in edema of swine epidemic area in Qinghai province.The results show that 33 strains(73.3% )having ideutified serotypes included O8,O25 ,O101, O138,O139,O141,O149 which had 10(22.2%), 1 (2.2%), 1 (2.2%) ,3(6.7%) ,7( 15.5%) ,5( 11.1% ) ,6( 13.3%) strains respectively,and the other 12 strains(26.7% )were not identified their serotypes.The predominant O serotypes were O8 ,O139 , O141 ,O149 that they took 62.2% of all seperated E.coli strains.
