猪源大肠埃希菌超广谱β-内酰胺酶的检测及其耐药性分析
Detection and Analysis of Drug Resistance of ESBLs in Escherichia coli Strains Isolated from Swine
摘要
Abstract
In order to investigate extended spectrum beta-lactamase( ESBLs) production and drug resist-ance of Escherichia coli strains isolated from swines in Liaoning areas,65 strains of E. coli isolates were tested. ESBLs was detected by K-B,and the genotypes of TEM,CTX-M,OXA and SHV were detected by PCR. The results indicated that 20 strains were producing ESBLs in 65 strains of E. coli,and the positive rate was 30. 77%. Nine strains were TEM type,one strain was CTX-M type,eight strains were TEM and CTX-M type,one strain was TEM and OXA type,one strain was TEM,CTX-M and OXA type. The drug re-sistance rate of ESBLs producing strain was higher than that of non-ESBLs strains,and all of them were multiple drug resistance strains. This study showed that the detection rate of ESBLs strains was higher, TEM type,TEM and CTX-M type were predominant genotypes in Liaoning areas.关键词
