Expression of the Fluoroquinolones Efflux Pump Genes acrA and mdfA in Urinary Escherichia coli Isolates [PDF]

open access: yesPolish Journal of Microbiology, 2017
Escherichia coli is one of the most frequent causes of urinary tract infections. Efflux system overexpression is reported to contribute to E. coli resistance to several antibiotics. Our aim in this study was to investigate the relation between antibiotic

AcrAB Efflux Pump Plays a Crucial Role in Bile Salts Resistance and Pathogenesis of Klebsiella pneumoniae [PDF]

open access: yesAntibiotics
Bile salts possess innate antibacterial properties and can cause significant damage to bacteria. To survive in the mammalian gut, Klebsiella pneumoniae has developed mechanisms to tolerate bile salts; however, the specific mechanisms remain unclear ...
