Corynebacterium pseudotuberculosis biovar ovis: evaluación de la sensibilidad antibiótica in vitro
Corynebacterium pseudotuberculosis biovar ovis: Evaluation of antibiotics susceptibility in vitro

Rev. argent. microbiol; 51 (4), 2019
Resumen Los objetivos de este trabajo fueron estudiar la sensibilidad antibiótica de aislamientos de Corynebacterium pseudotuberculosis procedentes de pequeños rumiantes e investigar la presencia de integrones que contienen genes de resistencia. Se estudiaron 15 aislamientos de diferentes fuentes por ...

Molecular detection of β-lactamase and integron genes in clinical strains of Klebsiella pneumoniae by multiplex polymerase chain reaction

Abstract INTRODUCTION: Infections caused by β-lactamase-producing gram-negative bacteria, such as Klebsiella pneumoniae, are increasing globally with high morbidity and mortality. The aim of the current study was to determine antimicrobial susceptibility patterns and the prevalence of antibiotic r...

The importance of integrons for development and propagation of resistance in Shigella: the case of Latin America

Braz. j. microbiol; 47 (4), 2016
Abstract In Latin America, the disease burden of shigellosis is found to coexist with the rapid and rampant spread of resistance to commonly used antibiotics. The molecular basis of antibiotic resistance lies within genetic elements such as plasmids, transposons, integrons, genomic islands, etc., which a...

Mobile genetic elements related to carbapenem resistance in Acinetobacter baumannii

Braz. j. microbiol; 47 (4), 2016
Abstract Acinetobacter baumannii is widely recognized as an important pathogen associated with nosocomial infections. The treatment of these infections is often difficult due to the acquisition of resistance genes. A. baumannii presents a high genetic plasticity which allows the accumulation of these res...

Characterization of the variable region in the class 1 integron of antimicrobial-resistant Escherichia coli isolated from surface water

Braz. j. microbiol; 47 (2), 2016
Abstract Fecal bacteria are considered to be a potential reservoir of antimicrobial resistance genes in the aquatic environment and could horizontally transfer these genes to autochthonous bacteria when carried on transferable and/or mobile genetic elements. Such circulation of resistance genes constitut...

Loop-mediated isothermal amplification assays for screening of bacterial integrons

Biol. Res; 47 (), 2014
BACKGROUND: The occurrence and prevalence of integrons in clinical microorganisms and their role played in antimicrobial resistance have been well studied recently. As screening and detection of integrons are concerned, current diagnostic methodologies are restricted by significant drawbacks and novel me...
