Abstract:The systematic investigation and study on sulfonamide resistance in Escherichia coli isolated from pigs in different areas were conducted.The minimum inhibitory concentrations(MIC)of sulfonamides were detected in 161 Escherichia coli isolates from pigs in Shandong,Inner Mongolia and Shanxi.The result showed that the sulfonamide resistance rates of the isolates were very high,the resistance rate to sulfafurazole(SF)was 91.30% and to sulfamethoxazole(SMZ)was 90.06%.Three pairs of primers were designed according to the gene orders of Dihydrofolate synthetase sul1,sul2 and sul3 available in GenBank.Sulfonamides resistance genes sul1,sul2 and sul3 were detected.The consistency rate between results of the drug sensitivity test and that of the resistance gene test was above 80% in Escherichia coli isolates from three provinces.
Keywords:pigs  Escherichia coli  sulfonamides  drug sensitivity test  resistance gene
