Detection of NDM-1, CTX-M-15 and qnrB4-producing Enterobacter 2 hormaechei isolates in Brazil
(American Society for Microbiology, 2015)
The first report of the qnrB19, qnrS1 and aac(6 ')-Ib-cr genes in urinary isolates of ciprofloxacin-resistant Escherichia coli in Brazil
(FUNDACO OSWALDO CRUZRIO DE JANEIRO, RJ, 2012)
In this study, we investigated the presence of plasmid-mediated quinolone resistance (PMQR) genes among 101 ciprofloxacin-resistant urinary Escherichia coli isolates and searched for mutations in the quinolone-resistance ...
Emergent multidrug-resistant nontyphoidal Salmonella serovars isolated from poultry in Brazil coharboring blaCTX-M-2 and qnrB or blaCMY-2 in large plasmids
(2019-09-01)
The number of foodborne gastroenteritis caused by nontyphoidal Salmonella (NTS) worldwide is estimated to be 80.3 million each year. Currently, antimicrobial-resistant NTS disseminated in the animal environment increases ...
Endemicity of the High-Risk Clone Klebsiella pneumoniae ST340 Coproducing QnrB, CTX-M-15, and KPC-2 in a Brazilian Hospital
(Mary Ann Liebert, Inc, 2018-12-13)
The dissemination of multiresistant Klebsiella pneumoniae carbapenemase (KPC)-2-producing Klebsiella pneumoniae isolates belonging to international high-risk clones poses a major health care threat. In this study, 48 ...
Distribution and functional identification of complex class 1 integrons
(Elsevier, 2013-10)
The emergence of extended-spectrum b-lactamases and plasmid-mediated resistance to quinolones has been previously found to be associated with the dissemination of complex class 1 integrons in Argentina. In this study, we ...
Identificación de genes de resistencia antibiótica tetQ, tetM, qnrS, qnrB en bacilos entéricos aislados de cavidad oral
(OdontologíaUniversidad El BosqueFacultad de Odontología, 2019)
: Enteric bacteria are considered transient micro-biota in the oral cavity and its distribution vary depending on diverse factors. They have been associated with an efficiency reduction of oral treatments, which relates ...
Differential distribution of plasmid-mediated quinolone resistance genes in clinical enterobacteria with unusual phenotypes of quinolone susceptibility from Argentina
(American Society for Microbiology, 2013-06)
We studied a collection of 105 clinical enterobacteria with unusual phenotypes of quinolone susceptibility to analyze the occurrence of plasmid-mediated quinolone resistance (PMQR) and oqx genes and their implications for ...
