Low selection of topoisomerase mutants from strains of Escherichia coli harbouring plasmid-borne qnr genes.
OBJECTIVES To investigate mutations in the type II topoisomerase genes in quinolone-resistant mutants selected from bacteria harbouring plasmid-borne qnr genes. METHODS Mutants were selected by nalidixic acid, ciprofloxacin and moxifloxacin from two Escherichia coli reference strains and corresponding transconjugants harbouring qnrA1, qnrA3, qnrB2 or qnrS1 genes. RESULTS The proportion of r...
متن کاملMultiplex PCR for detection of three plasmid-borne genes of enteroaggregative Escherichia coli strains.
We developed a novel multiplex PCR assay for enteroaggregative Escherichia coli (EAEC) detection, by using three plasmid-borne genes (the aggregative adherence [AA] probe, aap, and aggR). One or more of the loci were detected in 24 (86%) of 28 patient isolates analyzed. The multiplex PCR assay is a fast, convenient, and sensitive molecular test to detect EAEC.
متن کاملDetection of plasmid-mediated qnr genes among the quinolone-resistant Escherichia coli isolates in Iran.
INTRODUCTION Plasmid-mediated quinolone resistance, which complicates treatment, has been increasingly identified in Escherichia coli isolates worldwide. The purpose of this study was to identify the plasmid-mediated qnrA and qnrB genes among the quinolone-resistant Escherichia coli isolated from urinary tract infections in Iran. METHODOLOGY A total of 140 Escherichia coli isolates were colle...
متن کاملPhylogenetic analysis of Escherichia coli strains isolated from human samples
Escherichia coli (E. coli) is a normal inhabitant of the gastrointestinal tract of vertebrates, including humans. Phylogenetic analysis has shown that E. coli is composed of four main phylogenetic groups (A, B1, B2 and D). Group A and B1 are generally associated with commensals, whereas group B2 is associated with extra-intestinal pathotypes. Most enteropathogenic isolates, however, are assigne...
متن کاملPlasmid-borne virulence-associated genes have a conserved organization in virulent strains of avian pathogenic Escherichia coli.
Avian pathogenic Escherichia coli (APEC) is an important respiratory pathogen of poultry. Various virulence factors are responsible for determining the pathogenicity of these strains, and it is commonly believed they are encoded on large plasmids the strains carry. This study examined a series of strains, the pathogenicity of which had previously been determined by aerosol exposure, for possess...
