It has been recently reported the possibility in the bansfer of antimicrobial resistance to other animals and humans. In particular, vancomycin resistant enterococci (VRE), which have been known as a principal antimicrobial resistant bacteria in humans, have been increased as a pathogen of nosocomial infections. And then animal VRE were suspected as an origin of human VRE. In this study, we isolated Enterococcus spp. from animals, identified by bio- chemical tests, examined for antimicrobial susceptibility, and then compared the antimicrobial susceptibility of VRE among each other as well as human VRE. Enterococcus iecium (29%) was predominant in Enterococcus species (n=122) isolated from animal feces in this study. E. hirae, E. iecalis, E. casseliflam and E. gallinarum were also isolated as rates of 24%, 21%, 16% and 7%, respectively. The resistance of enterococci to penicillin and tetracycline were 66% and 78%, respectively, and the susceptibility of them to chloramphenicol was 66%. Antimicrobial susceptibility test has shown that 91% of VRE from humans (n=11) was susceptible to chloramphenicol and all resistant to penicillin, rifampin and streptomycin. Seventy-five percentage of VRE from chickens (n = 12) was susceptible to rifampin and resistances of them to penicillin, tetracycline and sbeptomycin were 75%, 83%, and l00%, respectively. Therefore, we confirmed the difference of antimicrobial susceptibility from animals and humans, and the antimicrobial susceptibility test could be one of the simple and useful methods for the epidemiological survey of VRE.
