Effect of Qnr on Plasmid Gyrase Toxins CcdB and ParE [PDF]

Antimicrobial Agents and Chemotherapy, 2015
ABSTRACT Plasmid toxins CcdB and ParE are part of addiction systems promoting plasmid maintenance. Both target host DNA gyrase, as do quinolones and plasmid-determined Qnr proteins that protect gyrase from quinolone inhibition. We cloned qnrB4 , qnrS1 , ccdB ,

Dissemination of ESBL and Qnr determinants in Enterobacter cloacae in Algeria [PDF]

Journal of Antimicrobial Chemotherapy, 2008
The aim of this study is to evaluate the prevalence and diversity of extended-spectrum beta-lactamases (ESBLs) in Enterobacter cloacae clinical isolates collected from Algerian hospitals and to verify the association with qnr genes.MICs were determined by Etest for isolates giving positive double-disc synergy tests, and all isolates were screened by ...

Emergence of Qnr determinants in human Salmonella isolates in Taiwan [PDF]

Journal of Antimicrobial Chemotherapy, 2008
The aim of this study was to determine the prevalence and characteristics of qnr-carrying Salmonella isolates from humans in southern Taiwan.A total of 446 Salmonella isolates collected between 2003 and 2006 were screened for qnrA, qnrB and qnrS by PCR experiments.

Pathogenicity and Antimicrobial-Resistance Profiles of Escherichia coli Isolated From Faeces of Tibetan Pigs Reared Under Intensive Conditions. [PDF]

Vet Med Sci
Tibetan pig farms host diverse Escherichia coli strains that resist multiple antibiotics and carry important disease genes, such as astA. These traits jump easily between bacterial groups, marking intensive pig production as a key reservoir and signalling the need for integrated animal–human surveillance and more careful antibiotic use.

Phylogenetic Analysis of Chromosomally Determined Qnr and Related Proteins [PDF]

Antimicrobial Agents and Chemotherapy, 2013
ABSTRACT qnr genes were discovered on plasmids by their ability to reduce quinolone susceptibility, but homologs can be found in the genomes of at least 92 Gram-negative, Gram-positive, and strictly anaerobic bacterial species.

Vibrionaceae as a possible source of Qnr-like quinolone resistance determinants [PDF]

Journal of Antimicrobial Chemotherapy, 2005
To gain insight into the functionality of qnr-like genes of several bacterial species of Vibrionaceae that may encode quinolone resistance determinants.A PCR-based strategy was used to obtain qnr-like genes of reference strains of Vibrio vulnificus CIP103196, Vibrio parahaemolyticus CIP71.2 and Photobacterium profundum CIP106289 that were sequenced ...

Detection of plasmid-mediated quinolone resistance determinants and qnrS expression in Enterobacteriaceae clinical isolates

Journal of Infection in Developing Countries, 2014
Introduction: Rapid dissemination of plasmid-mediated quinolone resistance (PMQR) has been reported in clinical isolates. Methodology: A total of 149 clinical isolates of Enterobacteriaceae were collected in Beijing and screened for PMQR genes ...

Effects of subinhibitory quinolone concentrations onfunctionality, microbial community composition, and abundance of antibiotic resistant bacteria and qnrS in activated sludge [PDF]

, 2021
Wastewater treatment plants (WWTPs) are continuously exposed to sub-inhibitory concentrations of antibiotics that are thought to contribute to the spreading of antibiotic resistant bacteria and antibiotic resistance genes, which are eventually released ...
