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...

Leucocidina de Panton-Valentine em amostras de Staphylococcus aureus resistente a meticilina: correlação com aspectos clínicos
Panton-Valentine Leucocidin in methicillin resistant Staphylococcus aureus isolates: correlation with clinical aspects

As infecções graves por Staphylococcus aureus resistente à meticilina (MRSA) aumentam de forma importante a morbidade e a mortalidade dos pacientes, com impacto também nos custos associados ao atendimento. Conhecer a prevalência e expressão de fatores de virulência tais como a leucocidina de Panto...

Genotyping and antimicrobial resistance in Escherichia coli from pig carcasses

Pesqui. vet. bras; 37 (11), 2017
The increasing antimicrobial resistance observed worldwide in bacteria isolated from human and animals is a matter of extreme concern and has led to the monitoring of antimicrobial resistance in pathogenic and commensal bacteria. The aim of this study was to evaluate the antimicrobial resistance profile ...

Lack of association between rrl and erm(41) mutations and clarithromycin resistance in Mycobacterium abscessus complex

Mem. Inst. Oswaldo Cruz; 112 (11), 2017
BACKGROUND Mycobacterium abscessus complex (MABC) includes species with high resistance rates among mycobacterial pathogens. In fact, MABC infections may not respond to clarithromycin treatment, which has historically been very effective against MABC infection. Molecular markers have been proposed to det...

KPC: Klebsiella pneumoniae carbapenemasa, principal carbapenemasa en enterobacterias

Rev. chil. infectol; 34 (5), 2017
Resumen En la actualidad, la diseminación de enterobacterias productoras de carbapenemasas se considera un grave problema en clínica debido al fracaso en el tratamiento de las infecciones que ellas producen. Entre las carbapenemasas, la enzima KPC se ha diseminado mundialmente y ha sido identificada en...

Antimicrobial resistance and plasmid replicons in Yersinia enterocolitica strains isolated in Brazil in 30 years

Braz. j. infect. dis; 21 (4), 2017
Abstract Some studies evaluated the resistance profile of the Y. enterocolitica strains isolated in diverse countries. However, in Brazil the isolation and the study of Y. enterocolitica are not common and therefore information about the antimicrobial resistance profile of this species in this country is...

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...

Over expression of AdeABC and AcrAB-TolC efflux systems confers tigecycline resistance in clinical isolates of Acinetobacter baumannii and Klebsiella pneumoniae

Abstract: INTRODUCTION: Due to the wide use of tigecycline in the treatment of severe infections caused by multidrug-resistant (MDR) bacteria, clinical resistance to tigecycline has increased in recent years. Here, we investigated the relationship between tigecycline resistance and the expression of ef...

Relationship between super antigenicity, antimicrobial resistance and origin of Staphylococcus aureus isolated

Colomb. med; 47 (1), 2016
Introduction: Staphylococcus aureus is a pathogen that causes food poisoning as well as hospital and community acquired infections. Objective: Establish the profile of superantigen genes among hospital isolates in relation to clinical specimen type, susceptibility to antibiotics and hospital or community...

Characterization of Escherichia coli virulence genes, pathotypes and antibiotic resistance properties in diarrheic calves in Iran

Biol. Res; 47 (), 2014
BACKGROUND: Calf diarrhea is a major economic concern in bovine industry all around the world. This study was carried out in order to investigate distribution of virulence genes, pathotypes, serogroups and antibiotic resistance properties of Escherichia coli isolated from diarrheic calves. RESULTS: Total...
