We determined the prevalence of plasmid-mediated quinolone resistance mechanisms among non-Typhi Salmonella spp. isolated from humans, food animals, and retail meat in the United States in 2007. Six isolates collected from humans harbored aac(6')Ib-cr or a qnr gene. Most prevalent was qnrS1. No animal or retail meat isolates harbored a plasmid-mediated mechanism.
我们确定了 2007 年从美国人类、食用动物和零售肉类中分离的非伤寒沙门氏菌属中质粒介导的喹诺酮耐药机制的流行率。从人类中分离的 6 株分离株携带 aac(6')Ib-cr 或 qnr 基因。最常见的是 qnrS1。没有动物或零售肉类分离株携带质粒介导的机制。
