禽致病性大肠杆菌的分离、O 血清群鉴定及药物敏感试验
Isolation,O Serogrouping and Drug Sensitivity Test of Avian Pathogenic Escherichia coli
摘要
Abstract
One hundred and ninety four avian pathogenic Escherichia .coli (APEC)isolated from different pathotypes of chickens in Hebei province,Shandong province,Henan province,Jiangsu province,Shanxi province and Liaoning province in China between May 2005 and March 201 6 were investigated by determination of biochemical characters,O serogroup identification and drug sensi-tivity test.Out of 1 94 isolates,124 strains(63.9%)could be grouped to serogroups O1 (3),O2 (26),O57(15),O65(47)and O78(33).The drug sensitivity test used eight antibiotics (ampicillin, neomycin,doxycycline,sulfamonomethoxine,tilmicosin,ciprofloxacin ceftiofur and florfenicol) by one strain of O1,O2,O57,O65,O78 serogroup,respectively.The results showed that all strains were sensitive to ciprofloxacin and neomycin,and resistance to other drugs at varying de-grees.This study demonstrated that the high prevalence of O65,O78,O2 and O57 isolates existed and provided the basis for the development of multivalent bacterin in future.关键词
