Abstract Nasal colonization with methicillin-resistant Staphylococcus aureus (MRSA) have increasingly been reported in healthy communities. This study aimed to assess the rate of S. aureus in general and MRSA in particular from nasal secretion of children in daycare centers in Vitória da Conquista, Braz...

Etiología y resistencia a antimicrobianos de la infección no complicada del tracto urinario
Etiology and antimicrobial resistance of uncomplicated urinary tract infections

Medicina (B.Aires); 77 (4), 2017
La infección urinaria no complicada en mujeres es un motivo frecuente de consulta e indicación de antimicrobianos. El objetivo de este estudio fue definir etiología y resistencia a antimicrobianos en episodios de infección urinaria no complicada. Este estudio prospectivo incluyó mujeres premenopáus...

Biosynthesized silver nanoparticles: are they effective antimicrobials?

Mem. Inst. Oswaldo Cruz; 112 (8), 2017
BACKGROUND Silver nanoparticles (AgNPs) are increasingly being used in medical applications. Therefore, cost effective and green methods for generating AgNPs are required. OBJECTIVES This study aimed towards the biosynthesis, characterisation, and determination of antimicrobial activity of AgNPs produ...

¿Se debe revisar la determinación de la CIM de colistín en Acinetobacter baumannii?

Rev. chil. infectol; 34 (4), 2017
Currently, there is a controversy in how to determine the minimal inhibitory concentration (MIC) of colistin against Acinetobacter baumannii. We compared three methods, concluding that the addition of Tween-80 (0.002%) to Müller-Hinton broth in the microdilution method could improve MIC determination an...

Interacciones evolutivas como un posible mecanismo de interacción medicamentosa: una aproximación para el control de la resistencia bacteriana

Rev. chil. infectol; 34 (4), 2017
Resumen En el siglo XXI, la humanidad se encuentra frente a una era post-antibiótica, en la cual es común la aparición de infecciones con una menor o nula alternativa terapéutica. En este contexto, se hace indispensable implementar medidas que optimicen el arsenal terapéutico disponible, generando n...

Evaluación de test rápidos y diseño de una estrategia para la detección y caracterización de carbapenemasas en cepas de bacilos gramnegativos

Rev. chil. infectol; 34 (4), 2017
Resumen Introducción: La detección de bacilos gramnegativos productores de carbapenemasas es compleja, existiendo actualmente varios test disponibles. La confirmación mediante la caracterización molecular de la enzima no está disponible en todos los laboratorios del país. Objetivo: Plantear una e...

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...

Abstract The present work discusses the technological and new selection criteria that should be included for selecting lactic acid bacteria for production of fermented meat. Lactic acid bacteria isolated from Bulgarian traditional fermented "lulanka" salami was studied regarding some positive technologic...

Pathogenic Vibrio species isolated from estuarine environments (Ceará, Brazil) - antimicrobial resistance and virulence potential profiles

An. acad. bras. ciênc; 89 (2), 2017
ABSTRACT Detection of virulent strains associated with aquatic environment is a current concern for the management and control of human and animal health. Thus, Vibrio diversity was investigated in four estuaries from state of Ceará (Pacoti, Choró, Pirangi and Jaguaribe) followed by antimicrobial susce...

Molecular characterization of methicillin-resistant Staphylococcus aureus isolated from blood in Rio de Janeiro displaying susceptibility profiles to non-ß-lactam antibiotics

Braz. j. microbiol; 48 (2), 2017
Abstract The distinction between healthcare-associated MRSA (HA-MRSA) and community-associated MRSA (CA-MRSA) infections has become increasingly blurred. We assessed the molecular characterization and antimicrobial resistance profile for MRSA isolates from blood. Most of all (81.9%) isolates are related ...
