Performance of rapid tests for carbapenemase detection among Brazilian Enterobacteriaceae isolates

Braz. j. microbiol; 49 (4), 2018
ABSTRACT The global emergence of carbapenemases led to the need of developing new methods for their rapid detection. The aim of this study was to evaluate the performance of the rapid tests for carbapenemase-producing and non-producing Enterobacteriaceae. Carbapenem non-susceptible Enterobacteriaceae fro...

Caracterización de metalo-β-lactamasas en aislados clínicos de Pseudomonas aeruginosa recuperados de pacientes hospitalizados en el Hospital Militar Central

Con el objetivo de caracterizar y determinar la frecuencia de genes que codifican metalo-β-lactamasas (MBL) en aislados clínicos de Pseudomonas aeruginosa (P. aeruginosa), se realizó un estudio transversal en el Hospital Militar Central (HMC) de Lima, Perú, entre enero y setiembre del 2016. Se an...

pMEX01, a 70kb Plasmid Isolated From Escherichia Coli That Confers Resistance to Multiple β-Lactam Antibiotics

Braz. j. microbiol; 49 (3), 2018
Abstract Multidrug-resistant microorganisms are of great concern to public health. Genetic mobile elements, such as plasmids, are among the most relevant mechanisms by which bacteria achieve this resistance. We obtained an Escherichia coli strain CM6, isolated from cattle presenting severe diarrheic symp...

Study of pandrug and heavy metal resistance among E. coli from anthropogenically influenced Delhi stretch of river Yamuna

Braz. j. microbiol; 49 (3), 2018
Abstract Escalating burden of antibiotic resistance that has reached new heights present a grave concern to mankind. As the problem is no longer confined to clinics, we hereby report identification of a pandrug resistant Escherichia coli isolate from heavily polluted Delhi stretch of river Yamuna, India....

Identificación de genes de resistencia a carbapenémicos en enterobacterias de hospitales de Perú, 2013-2017

RESUMEN La diseminación global de carbapenemasas es de importancia en la salud pública. El objetivo del estudio es describir la presencia de genes de resistencia a carbapenémicos tipo KPC y metalobetalactamasas en enterobacterias aisladas de 12 hospitales y remitidos al Laboratorio de Referencia Nacio...

Genes qnr en Enterobacteriaceae aisladas en un hospital de Venezuela

Rev. chil. infectol; 35 (2), 2018
Resumen Introducción: La resistencia de enterobacterias a quinolonas se ha difundido por el mundo, fenómeno presente también en Venezuela. El mecanismo de esta resistencia pudiera estar mediado por genes incluidos en el cromosoma bacteriano o transmitirse en el interior de plásmidos. Objetivo: Eval...

Clonal relationships, antimicrobial susceptibilities, and molecular characterization of extended-spectrum beta-lactamase-producing Escherichia coli isolates from urinary tract infections and fecal samples in Southeast Iran

Abstract INTRODUCTION: Multidrug-resistant (MDR) Escherichia coli, a species that is a leading cause of urinary tract infections (UTIs) and is a major global public health concern. This study was designed to detect the differences in antibiotic resistance patterns, the production and type of extended sp...

Clonal relation and antimicrobial resistance pattern of extended-spectrum β-lactamase- and AmpC β-lactamase-producing Enterobacter spp. isolated from different clinical samples in Tehran, Iran

Abstract INTRODUCTION: Here, we determined the genes encoding antibiotic resistance enzymes and virulence factors and evaluated the genetic relationship between Enterobacter spp. isolated from different clinical samples. METHODS: A total of 57 clinical isolates of Enterobacter spp. were tested for th...
