【摘要】 为了解东北地区狐源大肠杆菌对磺胺类药物耐药基因的流行情况,本实验共选取狐源大肠杆菌156株,采用PCR技术对磺胺类sulⅠ、sulⅡ和sulⅢ耐药基因进行检测。结果显示:磺胺类药物的耐药基因sulⅠ、sulⅡ和sulⅢ均有检出,分别为19. 23%(30/156)、44. 87%(70/156)、20. 51%(32/156)。并且来自不同地区的菌株对磺胺类药物的耐药性存在明显差异。结果表明,东北地区狐源大肠杆菌存在对磺胺类药物的耐药性。更多还原

【Abstract】 To understand the prevalence of sulfonamide-resistant genes in fox-derived Escherichia coli in Northeast China,we tested for sulfonamide-resistant genes sul Ⅰ,sul Ⅱ and sul Ⅲ in 156 selected strains of fox-derived Escherichia coli using PCR. We recorded sul Ⅰ,sul Ⅱ and sul Ⅲin 19%( 30/156),45%( 70/156) and 21%( 32/156) of tested strains,respectively. The resistance to sulfonamides differed by sample area. E. coli from foxes in northeast China had developed resistance to sulfonamides.更多还原
