从湖北天门某鸭场送检的具有明显输卵管炎的疑似鸭疫里默氏菌病死鸭的脑中分离出3株细菌。经细菌形态学鉴定、培养特性、生化试验、血清型鉴定、细菌16S r RNA的PCR鉴定及动物回归试验证明该3株菌为血清型1型的鸭疫里默氏菌,其致病性强,并分别命名为TM-R1,TM-R2,TM-R3。该3株菌对先锋霉素,美满霉素,氧哌嗪青霉素等高度敏感;对氯洁霉素、多粘霉素B、麦迪霉素、卡那霉素耐药;TM-R2、TM-R3对红霉素耐药;而TM-R1对红霉素中度敏感。
Dead ducks which were suspiciously infected with Riemerella anatipestifer from tianmen hubei showed obvious sal- pingitis.Three strains isolated from brains were proved as Riemerella anatipestifer of serotype 1 by the morphological identification, cultural characteristics, biochemical tests, serum identification, PCR identification of bacteria 16SrRNA and Regression test with animals.Three strains with highly pathogenicity were named TM-R1, TM-R2, TM-R3 .They were sensitive to Cephalosporin, Mino- cin, piperacillin and resistant to clindamycin, Polymyxin B, midecamycin, kanamycin, TM-R2, TM- R3 were resistant to erythro- mycin and TM-R1 was moderately sensitive to erythromycin.
