Plasmid-mediated mcr-1 in carbapenem-susceptible Escherichia coli ST156 causing a blood infection: an unnoticeable spread of colistin resistance in Brazil?

Clinics; 72 (10), 2017
OBJECTIVE: We describe an IncX4 pHC891/16mcr plasmid carrying mcr-1 in a colistin-resistant and carbapenem-susceptible E. coli isolate (HC891/16), ST156, which caused a blood infection in a Brazilian patient with gallbladder adenocarcinoma. METHODS: Strain HC891/16 was subjected to whole genome sequenci...

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...

Frecuencia de Chlamydia trachomatis en mujeres de edad fértil al usar PCR en tiempo real en el Servicio de Laboratorio del Hospital Carlos Andrade Marín
Recurrence of Chlamydia Trachomatis in women of childbearing age when using CRP in real time in the Laboratory Department of Carlos Andrade Marin Hospital

Cambios rev. méd; 16 (2), 2017
Introducción: Chlamydia trachomatis es una bacteria patógena comúnmente reportada como causante de infecciones del tracto urogenital. Materiales y métodos: Mediante este estudio se determinó la frecuencia de infección por C. trachomatis utilizando PCR en tiempo real en mujeres de edad fértil (18 ...

Use of green fluorescent protein labeled non-tuberculous mycobacteria to evaluate the activity quaternary ammonium compound disinfectants and antibiotics

Braz. j. microbiol; 48 (1), 2017
Abstract Although infections with NonTuberculous Mycobacteria have become less common in AIDS patients, they are important opportunistic infections after surgical procedures, likely because they are ubiquitous and not efficiently killed by many commonly used disinfectants. In Venezuela there have recentl...

Primer relevamiento de marcadores de resistencia a antibióticos en Enterobacteriaceae en Cochabamba, Bolivia
First survey on antibiotic resistance markers in Enterobacteriaceae in Cochabamba, Bolivia

Rev. argent. microbiol; 49 (1), 2017
A molecular survey was conducted in Cochabamba, Bolivia, to characterize the mechanism involved in the resistance to clinically relevant antibiotics. Extended Spectrum β-lactamase encoding genes and plasmid-mediated quinolone resistance (PMQR) markers were investigated in a total of 101 oxyimino-cep...

Stable expression of Mycobacterium bovis antigen 85B in auxotrophic M. bovis bacillus Calmette-Guérin

Mem. Inst. Oswaldo Cruz; 112 (2), 2017
BACKGROUND Bovine tuberculosis (TB) is a zoonotic disease caused by Mycobacterium bovis, responsible for causing major losses in livestock. A cost effective alternative to control the disease could be herd vaccination. The bacillus Calmette-Guérin (BCG) vaccine has a limited efficacy against bovine TB,...

Caracterização fenotípica e genotípica de Acinetobacter spp. e Pseudomonas aeruginosa produtores de carbapenemases

A resistência bacteriana a antibióticos é um grave e crescente problema de saúde pública de âmbito mundial. O principal, e mais eficiente, mecanismo de resistência aos β-lactâmicos em bacilos Gram-negativos é a produção de β-lactamases, que possuem a capacidade de hidrolisar o anel β-lactâ...

Antimicrobial resistance in Enterobacteriaceae in Brazil: focus on ß-lactams and polymyxins

Braz. j. microbiol; 47 (supl.1), 2016
ABSTRACT During the last 30 years there has been a dissemination of plasmid-mediated β-lactamases in Enterobacteriaceae in Brazil. Extended spectrum β-lactamases (ESBL) are widely disseminated in the hospital setting and are detected in a lower frequency in the community setting. Cefotaximases ...

High prevalence of plasmid-mediated quinolone resistance determinants in Enterobacter cloacae isolated from hospitals of the Qazvin, Alborz, and Tehran provinces, Iran

Abstract: INTRODUCTION: Plasmid-mediated quinolone resistance (PMQR) is a growing clinical concern worldwide. The main aims of this study were to detect qnr-encoding genes and to evaluate the clonal relatedness of qnr-positive Enterobacter cloacae isolates. METHODS: A total of 116 E. cloacae isolates ...
