新疆北疆地区猪源粪肠球菌的耐药性分析
Drug Resistance Analysis of Swine Enterococcus f aecalis in Northern Xinjiang
摘要
Abstract
In order to determine the drug resistance of swine Enterococcus f aecalis and the distri-bution of genotypes resistance in Northern Xinjiang,total 49 isolates were evaluated for their sen-sitivity to 8 antimicrobial drugs by Kirby-Baller disc diffusion method,and 9 relative resistance genes were detected by PCR method.The amplified fragments were sequenced and compared with the corresponding gene sequences in GenBank.Susceptibility test results showed that the isolates had the highest resistance rate to streptomycin,followed by penicillin and erythromycin,which were highly sensitive to nitrofurantoin and ampicillin.PCR detection results showed that the de-tection rate of β-lactam resistance gene tem was the highest(93.88%),followed by the tetracy-cline resistance gene tetM(85.71%),the detection rates of quinolones resistance gene gyrA and parC both were 42.86%,the detection rates of aminoglycoside resistance genes aph(3′)-Ⅲ,aac (6′)/aph2″and ant(6′)-Ⅰ were 36.73%,16.33% and 16.33%,respectively,and no mef A and ermB genes were detected.The results showed that the multidrug resistance of swine Enterococ-cus f aecalis in Northern Xinjiang was very serious,and its resistance phenotype was not consist-ent with the genotype.关键词
