Moreover, antimicrobial resistance in STEC has been a matter of increasing concern. The aim of this study was to investigate the prevalence and antimicrobial characteristics of STEC isolates from pork in Korea. We isolated 131 isolates of\n                    <jats:italic toggle=\"yes\">E. coli<\/jats:italic>\n                    from 334 pork samples collected from slaughterhouses and retail markets from 2008 to 2009. Among the 131 isolates, 6 (4.58%) were confirmed to belong to 6 different serotypes of STEC. All six STEC isolates contained\n                    <jats:italic toggle=\"yes\">stx1<\/jats:italic>\n                    and\n                    <jats:italic toggle=\"yes\">eaeA<\/jats:italic>\n                    virulence genes, and four of them additionally carried the\n                    <jats:italic toggle=\"yes\">hly<\/jats:italic>\n                    gene. The minimum inhibitory concentration (MIC) of 15 antibiotics (amoxicillin\/clavulanic acid, ampicillin, cephalothin, cefoxitin, ceftiofur, gentamicin, neomycin, streptomycin, nalidixic acid, ciprofloxacin, colistin, chloramphenicol, florfenicol, tetracycline and sulfamethoxazole\/trimethoprim) toward the STEC isolates was determined. As a result, three strains were associated with high MICs for florfenicol and chloramphenicol (64\u2009\u03bcg\/mL). Furthermore, all three strains were found to contain the florfenicol-resistant gene (\n                    <jats:italic toggle=\"yes\">floR<\/jats:italic>\n                    ) but not the chloramphenicol-resistant gene (\n                    <jats:italic toggle=\"yes\">cat<\/jats:italic>\n                    ).
