Computational discovery and functional validation of novel fluoroquinolone resistance genes in public metagenomic data sets

Abstract excerpt

BACKGROUND: Fluoroquinolones are broad-spectrum antibiotics used to prevent and treat a wide range of bacterial infections. Plasmid-mediated qnr genes provide resistance to fluoroquinolones in many bacterial species and are increasingly encountered in clinical settings. Over the last decade, several families of qnr genes have been discovered and characterized, but their true prevalence and diversity still remain...
