从2001 - 2003年安大略的腹泻猪和健康猪中获得的318株大肠杆菌分离株对19种抗菌药物进行了敏感性检查。用PCR方法检测了猪大肠杆菌对四环素、链霉素、磺胺类和安普霉素的耐药基因以及12个常见毒力基因的存在。杆菌大肠埃希菌的耐药率较高。安大略猪大肠杆菌分离株与其他国家相比是中等的，并且来自腹泻猪的分离株高于来自健康育肥猪的分离株。耐药谱表明，>= 8%的产肠球菌E.大肠杆菌（ETEC）。对喹诺酮类药物的耐药仅见于产肠球菌。大肠杆菌（
A total of 318 Escherichia coli isolates obtained from diarrheic and healthy pigs in Ontario from 2001 to 2003 were examined for their susceptibility to 19 antimicrobial agents. They were tested by PCR for the presence of resistance genes for tetracycline, streptomycin, sulfonamides, and apramycin and of 12 common virulence genes of porcine E. coli. Antimicrobial resistance frequency among E. coli isolates from swine in Ontario was moderate in comparison with other countries and was higher in isolates from pigs with diarrhea than in isolates from healthy finisher pigs. Resistance profiles suggest that cephamycinases may be produced by >= 8% of enterotoxigenic E. coli (ETEC). Resistance to quinolones was detected only in enterotoxigenic E. coli (
