Modern medicine is threatened by the rising tide of antimicrobial resistance, especially
among Gram-negative bacteria, where resistance to β-lactams is most often mediated by β …

In the last decade, extended-spectrum cephalosporin and carbapenem resistant Gram-
negative bacilli (GNB) have been extensively reported in the literature as being …

Objectives: Drug resistance among gram-negative bacteria is a worldwide challenge. Due to
the importance of drug-resistant Klebsiella pneumoniae and Escherichia coli strains in …

Background: The noteworthy spread of carbapenem-resistant K. pneumoniae (CR-KP)
isolates represents a significant safety threat. Objective: Determination of the …

Objective The present study aimed to determine the prevalence of virulence factors and
antimicrobial resistance profile of Pseudomonas aeruginosa strains isolated from Iranian …

Background: Klebsiella pneumoniae is a Gram-negative enteric bacterium that causes
nosocomial infections; this bacterium has survived from harsh condition using biofilm …

Background Extensive and inappropriate use of quinolones has led to growing resistance
rates to these broad‐spectrum antibiotics. The present study purposed to investigate the …

Introduction: Carbapenem-resistant Enterobacteriaceae (CRE) represents an urgent threat
worldwide. We aimed to investigate the frequency of carbapenem-resistant Klebsiella …

Pseudomonas aeruginosa is resistant to a wide range of extended spectrum-lactamases
(ESBLs) antibiotics because it produces several kinds of ESBLs. The goal of the current …

The aim of this study was to investigate the frequency, molecular characterization, virulence
genes, resistance genes and antimicrobial profile of nosocomial extended spectrum beta …
