Computational discovery and functional validation of novel fluoroquinolone resistance genes in public metagenomic data sets

BMC Genomics, 2017
Background Fluoroquinolones are broad-spectrum antibiotics used to prevent and treat a wide range of bacterial infections. Plasmid-mediated qnr genes provide resistance to fluoroquinolones in many bacterial species and are increasingly encountered in ...

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.

First report of qnr genes in Salmonella in The Netherlands [PDF]

Journal of Antimicrobial Chemotherapy, 2007
Sir, Currently, a variety of qnrA, B and S genes are commonly isolated from clinically important Enterobacteriaceae. Moreover, qnr genes have been detected in non-typhi Salmonella enterica serotypes in Europe, the United States, Africa, Australia and Asia.

Plasmid-mediated qnrA1 in Klebsiella pneumoniae ST147 in Recife, Brazil

International Journal of Infectious Diseases, 2014
Objectives: Qnr-mediated quinolone resistance is increasingly detected worldwide, but few studies have been carried out so far in Brazil. The aim of this study was to test for qnr determinants in isolates of ciprofloxacin-resistant Klebsiella pneumoniae.

PLASMID MEDIATED RESISTANCE TO QUINOLONES IN SALMONELLA

Archives of Veterinary Medicine, 2012
Plasmid mediated resistance to quinolones in Salmonella enterica is briefly presented. World wide spread of qnr determinants is evident, indicating the necessity for prudent use of antimicrobials in human and veterinary medicine.

Qnr-like pentapeptide repeat proteins in Gram-positive bacteria [PDF]

Journal of Antimicrobial Chemotherapy, 2008
To study the role of Qnr-like pentapeptide repeat proteins (PRPs) from several gram-positive species with quinolone resistance in vitro.A PCR-based strategy was used to clone and express genes coding for Qnr-like PRPs in Enterococcus faecalis, Enterococcus faecium, Listeria monocytogenes, Clostridium perfringens, C.

Enantiomeric profiling of quinolones and quinolones resistance gene qnrS in European wastewaters [PDF]

Water Research, 2020
Wastewater-based epidemiology (WBE) was applied for the first time in seven cities across Europe with the aim of estimating quinolones consumption via the analysis of human urinary metabolites in wastewater. This report is also the first pan-European study focussed on the enantiomeric profiling of chiral quinolones in wastewater.

Plasmid-mediated quinolone resistance determinant qnrS in Enterobacter cloacae [PDF]

Clinical Microbiology and Infection, 2006
PCR was used to investigate the occurrence of the plasmid-encoded quinolone resistance determinants qnrA and qnrS among diarrhoeagenic enterobacterial isolates recovered from Hanoi, Vietnam, during the period March 2001 to April 2002. In total, 162 Escherichia coli isolates, 28 Shigella isolates and three Enterobacter cloacae isolates were negative for

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 ...
