Abstract：To investigate the prevalence, phenicols resistance and mechanisms of Enterococcus spp. isolates, 44 swine feces samples were collected. Totally 34 isolates (77.3 %) were isolated and identified by enterococci selective agar and 16S rDNA sequence analysis. Antimicrobial agents sensitivity test showed that 61.8% (n=21) and 73.5 % (n=25) of the Enterococcus spp. isolates were resistant to chloramphenicol and florfenicol, respectively. Horizontal transfer resistance genes catA7, catA8, fexA, fexB, and cfr were detected in 11, 2, 7, 5, and 3 Enterococcus spp. isolates, respectively. Seven isolates harboured two kinds of phenicol resistance genes, simultaneously. The observation in this study suggested that high phenicols resistance rate in swine Enterococcus spp. isolates. More attention should be given on investigation and research of animals phenicols resistance enterococci.
