Sulfonamide-resistant Escherichia coli and Salmonella isolates from pigs and chickens in Ontario and Québec were screened for sul1, sul2, and sul3 by PCR. Each sul gene was distributed differently across populations, with a significant difference between distribution in commensal E. coli and Salmonella isolates and sul3 restricted mainly to porcine E. coli isolates.
采用聚合酶链反应(PCR)对安大略省和魁北克省猪和鸡身上分离出的耐磺胺类药物的大肠杆菌和沙门氏菌菌株进行了sul1、sul2和sul3基因筛查。每个磺胺类抗性基因在不同种群中的分布各异,共生大肠杆菌和沙门氏菌菌株的分布存在显著差异,且sul3主要局限于猪源大肠杆菌菌株。
