The aim of this study was to investigate the prevalence of antimicrobial resistance in Escherichia coli isolated from pigs and their farmhouse environment in Korea. A total of 585 E. coli were isolated in this study during 2006∼2007: 426 isolates from 492 pigs and 159 isolates from 312 farmhouse environment samples from 16 different pig farms. The most frequently observed resistance in pig fecal samples was to older antimicrobials such as tetracycline, streptomycin, and ampicillin. However, resistance to cephalosproins, β-lactam/ β-lactam inhibitor combination, and colistin was low. We found an inverse relationship between prevalence of resistant E. coli and animal age. Resistance rate and multi-drug resistance (MDR) was greater in young pigs (piglet and nursery) than for those from adult pigs (grower-finish and sow). Resistance of E. coli from farm environment such as floor, Iron partition, and ventilation was similar with those from pig fecal samples. Farm environment contaminated with MDR bacteria might be a possible source of infections to pigs. Thus, to control and reduce the antimicrobial resistance in pigs, we must also pay attention on the environment.
