演艺海豚混合感染大肠埃希氏菌和变形杆菌的检验分析

解剖了一条出现腹泻等症状、经治疗无效死亡的海豚 ,发现肺、肝、脾、胃等均有病变 ,从病变组织器官中分离到 7株细菌 ,通过菌株的形态、染色特征、生化特性、血清学鉴定 ,发现其中 5株菌株为大肠艾希氏菌 O8血清型 ,另 2株分别为普通变形杆菌和奇异变形杆菌。动物试验表明 ,大肠埃希氏菌和变形杆菌是海豚发病的致病菌。 7个菌株均对菌必治和先锋噻肟高敏 ,对氯霉素、链霉素、痢特灵等中敏 ,对青霉素 G、氨苄青霉素等耐药

Co infection of E coli and Proteus in a Dolphin for Performance

strains of bacteria were isolated from the lung,liver,spleen and stomach of the dolphin that died of diarrhea.According to their morphological and dyeing features,biochemical characterisitics and the results of the serological tests,five of these strains were identified as E.coli O 8 and the other two as proteus vulgaris and proteus mirabilis respectively.All of these strains were the causative pathogens of the diarrhea in the dolphin by the pathogenicity tests in animals and they were sensitive to chloramphenicol,streptomycin,furazolidone,etc,but insensible to penicillin G and ampicillin(AM).
