鸡源大肠埃希菌抗“O”血清型鉴定及药敏试验研究

SEROTYPING AND SUSCEPTIBIITY TESTING OF ESCHERICHIA COLI STRAINS IN CHINKENS

大肠埃希菌耐药性的增加及大肠埃希菌血清型众多,加大了药物防治大肠杆菌引发病症的难度。为了减少耐药菌株的产生及养殖者的经济损失,笔者对2011年4月～2012年7月门诊分离的鸡源大肠埃希菌进行抗"O"血清型鉴定及药敏试验,并与2005年11月～2007年4月门诊病死鸡疑似大肠埃希氏菌病例的相关统计数据进行了对比。

Increasing drug resistance and huge diversity of serotypes have made it more difficult to treat E.coli infections.Therefore,reduction＇ of drug resistance is needed to decrease the economic loss of farmers.The data presented here included anti-＂O＂ serotyping and susceptibility test of E.coli isolates from diseased chickens from April 2011 to July 2012 and were compared with that collected from November 2005 to April 2007.
