摘要:

对上海地区1个规模化养猪场和1个规模化养鸡场分离鉴定的40株粪肠球菌,采用微量肉汤稀释法对12种抗菌药物进行药敏试验,采用Riboprinter®微生物基因指纹鉴定系统检测分离菌株的基因指纹图谱,分别检测分离菌株中的核糖体型和耐药性。结果表明,在40株粪肠球菌中,80%以上为多重耐药菌株,有4株猪源粪肠球菌对万古霉素耐药,其中有2株表现为对万古霉素高度耐药(MIC>64 mg/L),且对链霉素和庆大霉素同时表现为高度耐药(MIC>2 048 mg/L)。从耐药表型和核糖体分型共同分析粪肠球菌的耐药性,发现多重耐药性严重,同一核糖体型菌株的耐药表型并非完全一致。

Abstract:

This study was to investigate the ribosome genotyping and antimicrobial resistance in Enterococcus faecalis strains isolated from 2 large-scale farms in Shanghai.40 isolates were evaluated for their sensitivity to 12 antimicrobial agents by broth microdilution,and the ribosome genotyping (ribotype) was characterized by the Riboprinter® Microbial Characterization System.The resistance rates of most antimicrobial drug were relatively high and multidrug resistant strains were detected with more than 80%.4 strains of Enterococcus faecalis isolated from pigs were resistant to vancomycin,including 2 strains of vancomycin highly resistant (MIC>64 mg/L) with the same time highly resistant to gentamicin and streptomycin (MIC>2 048 mg/L).The results showed that multidrug resistance of Enterococcus faecalis was a serious issue,and the resistant phenotypes of the same type of ribotype was not entirely consistent.

Key words: Enterococcus faecalis; antimicrobial resistance; ribosome genotyping; antimicrobial susceptibility test
