The aim of this study was to investigate the antimicrobial resistance in indicator bacteria isolated from healthy cattle in all provinces of the Republic of Korea. A total of 238 Escherichia coli and 72 Enterococcus spp. isolated from 252 fecal samples were examined for resistance to 16 and 12 antimicrobial agents, respectively. The most frequently observed resistance in E. coli isolates was to tetracycline (40.8%), followed by resistance to streptomycin (23.5%), and ampicillin (11.3%). E. faecium and E. faecalis showed resistance to tetracycline (45.7%, 62.2%), erythromycin (28.6%, 24.3%). Of the isolates, 28.5% of E. coli and 40.2% Enterococcus spp. strains showed resistances against more than two of antimicrobial agents tested, respectively. This study displays the prevalence of antimicrobial resistances in commensal enteric bacteria isolated from healthy cattle in Korea. It also indicates that antimicrobial resistance in food animals could be reduced with lower usage of antibiotics.
