Rev. chil. infectol; 35 (2), 2018
Resumen Introducción: Campylobacter es un importante agente de diarrea en el ser humano. En Ecuador, la información sobre Campylobacter es escasa y no existen antecedentes de susceptibilidad antimicrobiana. Objetivo: Describir la prevalencia de Campylobacter en niños con diarrea y su comportamiento ...

Escherichia coli is not a suitable fecal indicator to assess water fecal contamination by otters

Braz. j. biol; 78 (1), 2018
Abstract The detection of pathogenic microorganisms in aquatic environments is extremely relevant in terms of public health. As these laboratorial methodologies are usually difficult, expensive and time-consuming, they are frequently replaced by the assessment of fecal indicator bacteria, such as Escheri...

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...

Abstract: Objective: To investigate the correlation among pro- or anti-inflammatory cytokines and the two main gut microbiota phyla in obese children. Materials and methods: Anthropometric data were obtained from 890 children under 14 years old to determine the degree of obesity. Serum cytokine conce...

Caracterización de cepas de Campylobacter jejuni obtenidas desde carne de pollo y heces de aves de corral de la zona central de Chile

Rev. méd. Chile; 145 (12), 2017
Background Campylobacter jejuni is one of the main causal agents of food borne diseases. Infections with this pathogen are mainly caused by chicken meat consumption. Aim To characterize antibiotic resistance and virulence factors in C. jejuni strains obtained from chicken meat and poultry feces in Centr...

Evaluation of a selective chromogenic medium for detecting vancomycin-resistant enterococci

Braz. j. microbiol; 48 (4), 2017
ABSTRACT Rapid identification of vancomycin-resistant enterococci (VRE) can assist in choosing the appropriate treatment and preventing VRE spread. The performance of chromIDTM VRE agar was evaluated using 184 clinical isolates of Enterococcus spp. and reference strains. The test had a sensitivity of 95....

Dicistroviridae: A new viral purification technique

Rev. argent. microbiol; 49 (4), 2017
The family Dicistroviridae comprises three genera and about twenty species of RNA virus, most of them with health or agricultural importance. The Triatoma virus (TrV) is the only entomopathogenic virus identified in triatomine bugs up to the present. TrV replicates within the intestinal epithelial cells,...

Hibridização in situ fluorescente para diagnóstico de Brachyspira hyodysenteriae e B. pilosicoli ­em suínos

Pesqui. vet. bras; 37 (10), 2017
Disenteria Suína e Colite Espiroquetal são duas enfermidades importantes em suínos causados pela Brachyspira hyodysenteriae e Brachyspira pilosicoli, respectivamente. O diagnóstico eficaz dessas espécies é extremamente importante para a adoção de estratégias adequadas para o controle. Propõe-se...

Detection of vancomycin-resistant enterococci (VRE) in stool specimens submitted for Clostridium difficile toxin testing

Braz. j. microbiol; 48 (3), 2017
Abstract The aim of this study was to determine the association between Clostridium difficile (C. difficile) and vancomycin-resistant Enterococcus (VRE) and efficacy of screening stools submitted for C. difficile toxin assay for prevalence of VRE. Between April 2012 and February 2014, 158 stool samples s...
