Plasmid-Mediated Quinolone Resistance Genes in Escherichia coli Strains Isolated from Healthy Dogs [PDF]

Veterinary Sciences
Knowledge about the potential roles of pets as reservoirs for plasmid-mediated quinolone resistance is still limited in Türkiye. Thus, in our study, the presence of plasmid-mediated quinolone genes (qnrA, qnrB and qnrS) was examined by multiplex ...

Characterization of plasmid-mediated quinolone resistant genes among uropathogenic Escherichia coli isolates in Bushehr, south of Iran [PDF]

BMC Research Notes
Objectives Uropathogenic Escherichia coli (UPEC) is important in urinary tract infection (UTI). Quinolones and fluoroquinolones are broad-spectrum antibiotics for the treatment of UTI, although some of UPEC are resistant to these antibiotics.

Study of Plasmid-Mediated Quinolone Resistance in Klebsiella pneumoniae: Relation to Extended-Spectrum Beta-Lactamases

Journal of Pure and Applied Microbiology, 2022
Klebsiella pneumoniae (K. pneumoniae) is an important pathogen associated with various infections. The emergence of antibiotic resistances, such as quinolone resistance and those due to extended-spectrum beta-lactamases (ESBL), reduces the available ...

Molecular characterization of antimicrobial resistance related genes in E. coli, Salmonella and Klebsiella isolates from broilers in the West Region of Cameroon.

PLoS ONE, 2023
BackgroundAntibiotic resistance has become an enduring threat to human health. This has prompted extensive research to identify the determinants responsible in a bid to fight the spread of resistance and also develop new antibiotics.

Emerging coexistence of three PMQR genes on a multiple resistance plasmid with a new surrounding genetic structure of qnrS2 in E. coli in China

Antimicrobial Resistance and Infection Control, 2020
Background Quinolones are commonly used for treatment of infections by bacteria of the Enterobacteriaceae family. However, the rising resistance to quinolones worldwide poses a major clinical and public health risk.

Quinolone Resistance Genes and Their Contribution to Resistance in Vibrio cholerae Serogroup O139

Antibiotics, 2023
Background. Quinolones are commonly used for reducing the duration of diarrhea, infection severity, and limiting further transmission of disease related to Vibrio cholerae, but V. cholerae susceptibility to quinolone decreases over time.

Functional Identification and Evolutionary Analysis of Two Novel Plasmids Mediating Quinolone Resistance in Proteus vulgaris

Microorganisms, 2020
Plasmid-mediated quinolone resistance (PMQR) remains one of the main mechanisms of bacterial quinolone resistance and plays an important role in the transmission of antibiotic resistance genes (ARGs). In this study, two novel plasmids, p3M-2A and p3M-2B,
