New qnr Gene Cassettes Associated with Superintegron Repeats in Vibrio cholerae 01
(Centers for Disease Control and Prevention, 2019)
Prevalência dos genes qnr, aac (6’)Ib-cr e qepA entre isolados clínicos de enterobactérias
(Universidade Federal de São Paulo (UNIFESP), 2011-04-27)
The aim of this study was evaluated the frequency of the plasmid mediated quinolone resistance genes qnr, aac(6’)Ib-cr and qepA. Were evaluated 231 Enterobacteriaceae isolated during the June of 2008 by the Central Laboratory ...
Spread of the qnrVC Quinolone Resistance Determinant in Vibrio cholerae
(American Society for Microbiology, 2018)
Detección de genes qnr en aislamientos de enterobacterias con resistencia simultánea a fluorquinolonas y oximinocefalosporinas
(Universidad Nacional del Litoral. Facultad de Bioquímica y Ciencias Biológicas, 2010-12)
Se analizaron cepas de enterobacterias con resistencia simultánea a oximinocefalosporinas y fluorquinolonas aisladas entre febrero y agosto de 2007 de pacientes hospitalizados en el Sanatorio Médico de Diagnóstico y ...
Characterization of a novel variant of the quinolone-resistance gene qnrB (qnrB89) carried by a multi-drug resistant citrobacter gillenii strain isolated from farmed salmon in Chile
(MDPI, 2021)
The main objective of this study was to characterize using whole-genome sequencing analysis, a new variant of the qnrB gene (qnrB89) carried by a fluoroquinolone-susceptible bacterium isolated from mucus of farmed Salmo ...
QnrE1, a member of a new family of plasmid-located quinolone resistance genes, originated from the chromosome of enterobacter species
(American Society for Microbiology, 2017-05)
qnrE1, found in a clinical Klebsiella pneumoniae isolate, was undetectable by PCR assays used for the six qnr families. qnrE1 was located on a conjugative plasmid (ca. 185 kb) and differed from qnrB alleles by 25%. ...
Epidemiology of qnrVC alleles and emergence out of the Vibrionaceae family
(Society for General Microbiology, 2015)
Transferable mechanisms of quinolone resistance from 1998 onward
(Universidad Continental, 2019-10)
While the description of resistance to quinolones is almost as old as these antimicrobial agents themselves, transferable mechanisms of quinolone resistance (TMQR) remained absent from the scenario for more than 36 years, ...
Evaluation of the Susceptibility profiles, genetic similarity and presence of qnr gene in Escherichia coli resistant to ciprofloxacin isolated in Brazilian hospitals
(Brazilian Society of Infectious Diseases, 2007-02-01)
Increasing quinolone resistance has been reported worldwide, mainly among clinical isolates of Escherichia coli. The objectives of this study were to determine the susceptibility profile, the genetic relatedness, and the ...
