Characterization of quinolone-resistant Enterobacteriaceae strains isolated from poultry in Western Algeria: First report of qnrS in an Enterobacter cloacae

Prevalence and characterization of extended spectrum beta-lactamase-producing Enterobacter cloacae strains in Algeria.

INTRODUCTION Expended spectrum β-lactamase (ESBL)-producing Enterobacter cloacae is an important nosocomial pathogen. In this study, the prevalence and the molecular epidemiology of ESBL producing E. cloacae strains isolated from various hospitals in Annaba, Algeria were investigated. METHODOLOGY The study involved 63 isolates of E. cloacae obtained during 2009 at the four hospitals in Annaba...

Particular Distribution of Enterobacter cloacae Strains Isolated from Urinary Tract Infection within Clonal Complexes

Background: Based on biochemical properties, Enterobacter cloacae represents a large complex of at least 13 variant species, subspecies, and genotypes that progressively identified as the most species causing hospital-acquired infections. The aim of this study was to determine the relevance between phylogenetically related strains within the E. cloacae complex and the frequency of urinary tract...

First detection of plasmid-mediated quinolone resistance (qnrA and qnrS) in Escherichia coli strains isolated from humans in Scandinavia.

strain with no parC mutations. This is consistent with previous findings that gyrA mutations are necessary for quinolone resistance, whereas parC mutations appear to be complementary, as resistant strains do not carry parC mutations alone. – 6 Some studies further suggest that additional parC mutations facilitate increasing levels of resistance, but our study did not support this. For example, ...

First report of a nonmetallocarbapenemase class A carbapenemase in an Enterobacter cloacae isolate from Colombia.

Carbapenemases are a growing concern worldwide since they threaten the efficacy of carbapenems, the most potent -lactam antibiotics. Nonmetallocarbapenemase class A (NMC-A) was identified in 1990 from a clinical isolate of Enterobacter cloacae, and since its first report in France (1), this rare enzyme has been found only in the United States (Seattle, WA, and New York, NY), Argentina, and Finl...
