Differential fitness costs of different qnr determinants.

, 2012
Plasmid loss was measured in the acrAB defective E. coli KZM120 strain (black bars), in the wild-type strain E. coli MC4100 (gray bars) and in the hns defective E. coli JMG100 strain (white bars). pGEM-T, empty vector; pBS3.25, plasmid with Smqnr; pBS18,

In-vitro mutagenesis of qnrA and qnrS genes and quinolone resistance in Escherichia coli [PDF]

Clinical Microbiology and Infection, 2007
Plasmid-mediated quinolone resistance is being reported increasingly worldwide among isolates of enterobacteria. This resistance is mostly associated with Qnr-like determinants that confer resistance to quinolones, e.g., nalidixic acid, and reduced susceptibility to fluoroquinolones. This study investigated whether amino-acid substitutions in QnrA1 and

Cefotaxime-Resistant Salmonella enterica in Travelers Returning from Thailand to Finland

Emerging Infectious Diseases, 2014
During 1993–2011, cefotaxime resistance among Salmonella enterica isolates from patients in Finland increased substantially. Most of these infections originated in Thailand; many were qnr positive and belonged to S.

Mechanisms of quinolone resistance and implications for human and animal health [PDF]

Veterinarski Glasnik, 2010
Quinolone antibiotics have been widely used in human and veterinary medicine. This has caused the development of resistance and difficulties in the treatment of complicated bacterial infections in humans.

Longitudinal Associations of Oxaliplatin Treatment With Chemotherapy‐Induced Peripheral Neuropathy in Colorectal cancer Survivors up to 2 Years Post‐Treatment

International Journal of Cancer, EarlyView.
ABSTRACT Chemotherapy‐induced peripheral neuropathy (CIPN) is a potentially long‐term consequence of oxaliplatin‐based chemotherapy for colorectal cancer (CRC). Oxaliplatin dosing is based on body surface area (BSA), but lean body mass (LBM) may influence susceptibility to long‐term CIPN.

Inhibition of QNR cell differentiation correlates with TGF-β3 down-regulation by v-Src.

, 2013
(A) QPCR analysis of TGF-β3 mRNA levels in 7-day-old (E7) embryonic QNR seeded for 1 (E7+1), 8 (E7+8) or 18 (E7+18) days. Results were normalized based on HPRT and TBP transcript levels and presented in relative arbitrary units, using values obtained for

Manure Composting as a Strategy to Mitigate Antibiotic Resistance Dissemination in Agricultural Systems

Land Degradation &Development, EarlyView.
ABSTRACT Livestock manure is a valuable agricultural resource but may introduce antibiotic residues and antibiotic resistance genes (ARGs) into the environment. This review critically evaluates the fate of antibiotics and ARGs during manure composting and identifies the principal factors controlling their attenuation.

Establishment of multiplex PCR for detection of genes related to Quinolone resistance

Vietnam Journal of Science, Technology and Engineering, 2018
Background/aims: It has been shown that quinolone resistance arises due to mutations in the quinolone resistance-determining regions of the drug targets.

First Report of blaCTX‐M‐15 in a Marine Thermotolerant Enterobacter Isolate From Bangladesh: Genomic Insights Into Halotolerance and Antimicrobial Resistance

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
Marine‐derived Enterobacter kobei, exhibiting thermotolerance and salt tolerance, is ESBL‐producing and harbors AMR genes (blaCTX‐M‐15, qnrS1) and mobile genetic elements, indicating environmental spread of antimicrobial resistance. ABSTRACT Marine ecosystems are becoming important reservoirs for antimicrobial resistance (AMR). However, genomic data on
