Broader Distribution of Plasmid-Mediated Quinolone Resistance in the United States [PDF]

Antimicrobial Agents and Chemotherapy, 2005
ABSTRACT The plasmid-encoded quinolone resistance gene qnrA confers low-level quinolone resistance, facilitating selection of higher-level resistance. Epidemiologic surveys for qnrA were extended to isolates of Enterobacter spp. and to quinolone-susceptible

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. In discovering plasmid mediated resistance to quinolones antimicrobial resistance monitoring for β-lactam antibiotics is ...

qnrB , Another Plasmid-Mediated Gene for Quinolone Resistance [PDF]

Antimicrobial Agents and Chemotherapy, 2006
ABSTRACT A novel plasmid-mediated quinolone resistance gene, qnrB , has been discovered in a plasmid encoding the CTX-M-15 β-lactamase from a Klebsiella pneumoniae strain isolated in South India. It has less than 40% amino acid identity with the original qnr (

Plasmid-mediated Quinolone Resistance among Non-TyphiSalmonella enterica Isolates, USA

Emerging Infectious Diseases, 2010
We determined the prevalence of plasmid-mediated quinolone resistance mechanisms among non-Typhi Salmonella spp. isolated from humans, food animals, and retail meat in the United States in 2007. Six isolates collected from humans harbored aac(6′)Ib-cr or

In vitro and in vivo persistence of IncN plasmids carrying qnr genes in uropathogenic Escherichia coli isolates

Journal of Global Antimicrobial Resistance, 2020
Objectives: This study aimed to evaluate the persistence of the plasmid-mediated quinolone resistance (PMQR) among uropathogenic Escherichia coli strains grown under or without exposure to subinhibitory concentrations of ciprofloxacin.

Is plasmid-mediated quinolone resistance a clinically significant problem? [PDF]

Clinical Microbiology and Infection, 2008
Although resistance to quinolones is commonly chromosomally-encoded in Enterobacteriaceae, the emergence of plasmid-mediated quinolone resistance (PMQR) has also been reported, with at least three known resistance mechanisms to date, i.e., Qnr, aminoglycoside acetyltransferase AAC(6')-Ib-cr and QepA.

Mutational Diversity in the Quinolone Resistance-Determining Regions of Type-II Topoisomerases of Salmonella Serovars

Antibiotics, 2021
Quinolone resistance in bacterial pathogens has primarily been associated with mutations in the quinolone resistance-determining regions (QRDRs) of bacterial type-II topoisomerases, which are DNA gyrase and topoisomerase IV. Depending on the position and

Plasmid-mediated quinolones resistance in clinically important bacteria [PDF]

The Journal of Qazvin University of Medical Sciences, 2018
Quinolones are synthetic and commonly used antibiotics for treatment of multiple clinical infections in the world. Quinolones are clinically important antibiotics, as an ideal component, because of high potency, broad-spectrum activity, good bioavailability and a potentially low incidence of side-effects.

Distribution of plasmid-mediated quinolone resistance in Gram-negative bacteria from a tertiary hospital in Nigeria

Indian Journal of Pathology and Microbiology, 2016
Background: Until recently, mechanisms of resistance to quinolones in Gram-negative bacteria were believed to be only chromosome encoded. However, emergence of plasmid-mediated quinolone resistance (PMQR) has been reported worldwide.

Integrating One Health to Mitigate the Emergence and Spread of Antimicrobial Resistance in Livestock and Aquaculture

Animal Research and One Health, EarlyView.
Antimicrobial resistance (AMR) is an escalating global threat driven by antimicrobial use in aquaculture and livestock. Resistant pathogens and genes can spread across humans, animals, and the environment through interconnected ecosystems. Using a One Health approach, this review emphasizes antimicrobial stewardship, regulatory strengthening, enhanced ...
