Portación nasal de Staphylococcus aureus en el personal de salud de áreas críticas de un Hospital Pediátrico durante julio-setiembre 2018

Las infecciones intrahospitalarias (IIH) son causa de elevada morbimortalidad y representan un problema sanitario importante. El personal de salud es reservorio y potencial transmisor de los agentes etiológicos de las mismas. S. aureus es uno de los microorganismos implicados, por lo tanto es importante...

Escherichia coli diarrogénicos, identificación de patotipos y fenotipos de resistencia antimicrobiana en aislados cubanos
Diarrheagenic Escherichia coli: identification of pathotypes and antimicrobial resistance phenotypes in Cuban isolates

Rev. cuba. med. trop; 72 (1), 2020
Introducción: En los países en vías de desarrollo las enfermedades diarreicas agudas son causa frecuente de morbilidad y mortalidad. Entre las primeras causas se encuentra Escherichia coli diarrogénicos, que afecta a pacientes en edades extremas de la vida y con inmunodeficiencias. Objetivo: Identi...

Characteristics of virulence, resistance and genetic diversity of strains of Salmonella Infantis isolated from broiler chicken in Brazil

Pesqui. vet. bras; 40 (1), 2020
Salmonella Infantis is frequently associated with human infections worldwide and is transmitted by consumption of contaminated foods, particularly those of animal origin, especially the chicken meat. We aimed to evaluate virulence characteristics, antimicrobial resistance and the genetic similarity of 51...

Genomic basis of antibiotic resistance in Vibrio parahaemolyticus strain JPA1

Mem. Inst. Oswaldo Cruz; 114 (), 2019
A multi-resistant strain of Vibrio parahaemolyticus was isolated from a tropical estuary in Rio de Janeiro, Brazil. Genome sequencing was conducted to establish the molecular basis of antibiotic resistance in this organism. The genetic content of this strain revealed it to be a non-virulent lineage that ...

Relationships between phagocytosis, mucoid phenotype, and genetic characteristics of Klebsiella pneumoniae clinical isolates

Abstract INTRODUCTION The relationships between phagocytosis, and mucoid phenotype, plasmid profile and virulence, and resistance genetic characteristics of Klebsiella pneumoniae clinical isolates were evaluated. METHODS Thirty isolates were used to determine the mucoid aspect. Four were selected for...

Diseño de estrategias para controlar la resistencia a los antimicrobianos utilizando herramientas de bioinformática y modelado molecular

El éxito del tratamiento de las enfermedades infecciosas se ha visto comprometido en los últimos años debido a la diseminación de genes de resistencia a antibióticos entre las bacterias patógenas. Estos genes de resistencia a antibióticos son transportados por plásmidos, los cuáles son transfer...

Construction of a cassette for cloning and analysis of replicons

Acta cient. venez; 51 (1), 2000
The aim of this work was the construction of a cassette, i.e., a non-replicative molecule formed by linkage of an antibiotic resistance gene and a multiple cloning site. This cassette would allow the cloning and analysis of a wide range of replicons. The aac(6')-lc amikacin gene was isolated and ligated ...
