¿La detección de toxinas de Clostridioides difficile es necesaria cuando se detecta la enzima glutamato deshidrogenasa?

Gac. méd. Méx; 157 (1), 2021
Resumen Introducción: Clostridioides difficile causa diarrea y colitis pseudomembranosa. Su diagnóstico se realiza con la detección de glutamato-deshidrogenasa (GDH) o las toxinas A y B y se confirma con pruebas de amplificación de ácidos nucleicos. Objetivo: Definir si la determinación de GDH es...

Detection of toxigenic Clostridioides --#1;Clostridium--#3; difficile: Usefulness of two commercially available enzyme immunoassays and a PCR assay on stool samples and stool isolates

Rev. argent. microbiol; 50 (1), 2018
The best laboratory diagnostic approach to detect Clostridioides --#1;Clostridium--#3; difficile infection (CDI) is a subject of ongoing debate. With the aim of evaluating four laboratory diagnostic methods, 250 unformed stools from patients with suspected CDI submitted to nine medical center laboratorie...

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...

Can microcystins affect zooplankton structure community in tropical eutrophic reservoirs?

Braz. j. biol; 76 (2), 2016
Abstract The aim of our study was to assess whether cyanotoxins (microcystins) can affect the composition of the zooplankton community, leading to domination of microzooplankton forms (protozoans and rotifers). Temporal variations in concentrations of microcystins and zooplankton biomass were analyzed in...

Infección diseminada por Staphylococcus aureus positivo para leucocidina de Panton-Valentine en un niño

Arch. argent. pediatr; 114 (2), 2016
La leucocidina de Panton-Valentine (LPV) es una exotoxina producida por muchas cepas de Staphylococcus aureus, y un importante factor de virulencia. Una infección por S. aureus positivo para LPV deriva en infecciones rápidas y graves de partes blandas y neumonía necrosante en adolescentes sanos, y la ...

Occurrence and toxicity of Microcystis aeruginosa (Cyanobacteria) in the Paraná River, downstream of the Yacyretá dam (Argentina)

Rev. biol. trop; 64 (1), 2016
AbstractCyanobacteria constitute the main toxin producers in inland water ecosystems and have extensive global distribution. The presence of hepatotoxins in aquatic environments is hazardous to human and animal health; even though the presence and identification of hepatotoxic microcystins in rivers and ...
