Molecular and biochemical characterization of CTX-M-131, a natural Asp240Gly variant derived from CTX-M-2, produced by a Providencia rettgeri clinical strain in São Paulo, Brazil
(American Society for Microbiology, 2015-03)
CTX-M-131 is a natural Asp240Gly variant from the CTX-M-2 group detected in a Providencia rettgeri clinical strain from Brazil. Molecular analysis showed that blaCTX-M-131 was inserted in a complex class 1 integron harbored ...
Evaluation and characterization of plasmids carrying CTX-M genes in a non-clonal population of multidrug-resistant Enterobacteriaceae isolated from poultry in Brazil
(2016-08-01)
The increasing presence of ESBL-producing bacteria in food-producing animals might impact on public health. In this study, ESBL-producing enterobacteria were investigated in the microbiota of chickens produced in Brazil. ...
The presence of genes encoding for different virulence factors in clonally related Escherichia coli that produce CTX-Ms
(ELSEVIER SCIENCE INCNEW YORK, 2012-04)
Successful international clones have recently emerged among Escherichia coli that produce CTX-M beta-lactamases as important causes of community-onset urinary tract and bloodstream infections. One hundred and seven isolates ...
Molecular characteristics of extended-spectrum beta-lactamase-producing Escherichia coli from Rio de Janeiro, Brazil
(WILEY-BLACKWELL, 2011)
Twenty-five extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli clinical isolates from Rio de Janeiro, Brazil were characterized by isoelectric focusing, PCR and sequencing of bla(ESBL) genes, plasmid-mediated ...
ESBL-Producing Escherichia coli Carrying CTX-M Genes Circulating among Livestock, Dogs, and Wild Mammals in Small-Scale Farms of Central Chile
(2021)
Antibiotic-resistant bacteria of critical importance for global health such as extended-spectrum beta-lactamases-producing (ESBL)-Escherichia coli have been detected in livestock, dogs, and wildlife worldwide. However, the ...
Detection of class 1 and 2 integrons, extended-spectrum β-lactamases and qnr alleles in enterobacterial isolates from the digestive tract of Intensive Care Unit inpatients
(Elsevier Science, 2010-11)
In this study, we searched for extended-spectrum β-lactamases (ESBLs), class 1 and 2 integrons, and qnrA, qnrB and qnrS genes in 56 oxyimino-cephalosporin and/or ciprofloxacin-resistant enterobacterial isolates obtained ...
Extended-spectrum β-lactamases, transferable quinolone resistance, and virulotyping in extra-intestinal E. coli in Uruguay
(Journal of Infection in Developing Countries, 2016-01)
Introduction: To characterize extended-spectrum β-lactamases (ESBLs) and plasmid-mediated quinolone resistance (PMQR) genes in Escherichia coli isolates obtained from extra-intestinal samples in three Uruguayan hospitals. ...
Draft genome sequence of a multidrug-resistant Aeromonas hydrophila ST508 strain carrying rmtD and bla(CTX-M-131) isolated from a bloodstream infection
(Elsevier Sci Ltd, 2017)
Here we report the draft genome sequence of a multidrug-resistant (MDR) Aeromonas hydrophila strain belonging to sequence type 508 (ST508) isolated from a human bloodstream infection. Assembly and annotation of this draft ...
