Plasmid-mediated resistance to quinolones is increasingly reported in studies of Enterobacteriaceae. Using a PCR-based strategy, a series of gram-negative species were screened for qnrA-like genes. Shewanella algae, an environmental species from marine and fresh water, was identified as its reservoir. This is a one of the very few examples of progenitor identification of an acquired antibiotic resistance gene.
在肠杆菌科细菌的研究中,越来越多地报道了质粒介导的喹诺酮耐药性。采用基于聚合酶链反应(PCR)的策略,对一系列革兰氏阴性菌进行了qnrA样基因筛选。海藻希瓦氏菌是一种来自海洋和淡水的环境细菌,被确定为该基因的储存宿主。这是获得性抗生素耐药基因溯源鉴定的极少数例子之一。
