| 摘 要： | 对四川省成都市某种禽场的156个死胚进行沙门氏菌的分离鉴定及药物敏感性检测.本试验采用沙门氏菌显色培养基、肠杆菌科生化鉴定管、三糖铁试验、沙门氏菌多价血清和16S rRNA PCR鉴定5种方法对疑似菌株进行鉴定,并用6种毒力岛基因将分离的沙门氏菌进行PCR鉴定.结果显示,沙门氏菌的分离率为15.4%(24/156),其中伤寒沙门氏菌占58.3%(14/24);fimY、invA和mgtC毒力基因的检测率均为100%;本试验分离菌对大部分沙门氏菌临床药物表现出明显的耐药性.

| Abstract: | In a poultry farm of Chengdu city,Sichuan province,isolation,identification and drug sensitivity test of Salmonella were conducted from 156 dead embryos.In this experiment,we used Salmonella chromogenic medium,biochemical identification of enterobacteriaceae,trisaccharide iron experiment,Salmonella polyvalent serum and 16S rRNA PCR to identify suspected strains,PCR identification of isolated Salmonella were conducted with 6 kinds of virulence genes.The results concluded that Salmonella separation rate was 15.4%(24/156),including Salmonella typhi accounted for 58.3%(14/24); Detection rates of fimY,invA and mgtC virulence genes were all 100%;The isolated Salmonella were resistant to most clinical drugs to Salmonella. |
