Abstract

Fluoroquinolones are important antimicrobial drugs used to treat human infections, and resistance is rare in the United States for isolates from human and animal sources. Recently, a number of isolates from swine cecal contents and retail pork products from National Antimicrobial Resistance Monitoring System (NARMS) surveillance exhibited decreased susceptibility to ciprofloxacin. We identified two quinolone resistance plasmids that are predominantly responsible for this phenomenon and found them distributed among several serotypes isolated throughout the United States.

摘要

氟喹诺酮类药物是用于治疗人类感染的重要抗菌药物,在美国,从人和动物来源的分离物中,耐药性很少见。最近,从国家抗菌药物耐药性监测系统(NARMS)监测的猪盲肠内容物和零售猪肉产品中分离出的许多分离物对环丙沙星的敏感性降低。我们确定了两种主要导致这种现象的喹诺酮类耐药质粒,并发现它们分布在美国各地分离的几种血清型中。
