In 1998, the first plasmid-mediated gene involved in quinolone resistance (currently named
qnrA1) was reported. Extra qnr-like plasmid-mediated genes (qnrB, qnrS, qnrC, qnrD) and …

Clin Microbiol Infect 2011; 17: 873–880 Abstract Intestinal carriage of extended‐spectrum
beta‐lactamase (ESBL)‐producing bacteria in food‐producing animals and contamination of …

Objectives To evaluate the possible occurrence of carbapenemase-producing Escherichia
coli and Klebsiella spp. strains in domestic animals. Methods Veterinary clinical E. coli (n …

Background: Urinary tract infection (UTI) is one of the most common childhood bacterial
infections and Escherichia coli is the major pathogen. Producing β-lactamase enzymes are …

Background As an opportunistic pathogen, Escherichia coli (E. coli) is widely recognized as
the main cause of nosocomial infections as well as some disorders especially those …

Background Escherichia coli carrying clinically important antimicrobial resistances [ie,
against extended-spectrum-beta-lactamases (ESBL)] are of high concern for human health …

We compared the distribution of phylogenetic groups and nine virulence factors among the
pathogenic (isolated from blood and urine) and commensal (isolated from feces of healthy …

Objective (s) Extensive use of quinolones has been associated with raising level of
resistance. In the current, we focused on assessing the prevalence of Escherichia coli …

Background: The increasing prevalence of multidrug-resistant (MDR) Escherichia coli
strains, especially extended-spectrum beta-lactamase (ESBL)-producing strains, has …

Abstract Background The incidence of Proteus mirabilis antimicrobial resistance, especially
that mediated by extended-spectrum β-lactamases (ESBLs), has increased. We investigated …
