Complete substitution of the Brazilian endemic clone by other methicillin-resistant Staphylococcus aureus lineages in two public hospitals in Rio de Janeiro, Brazil

Braz. j. infect. dis; 21 (2), 2017
Abstract Staphylococcus aureus is an important cause of bloodstream infections. Therefore, the main purpose of this work was to characterize a collection of 139 S. aureus isolates from bloodstream infections in two public hospitals in relation to their antimicrobial susceptibility profile, staphylococcal...

The effects of ozone on bacterial growth and thiol-disulphide homeostasis in vascular graft infection caused by MRSA in rats

Acta cir. bras; 32 (3), 2017
Abstract: Purpose: To investigate the microbiological, inflammatory and oxidant effects of adjuvant ozone administration in experimental rat vascular graft infection model which has not been previously investigated. Methods: Forty adult Wistar rats were divided into Sham, Control, Vancomycin, Ozone, Va...

Incidence and treatment of methicillin-resistant S. aureus infection in cystic fibrosis patients: a cohort study

Braz. j. infect. dis; 21 (1), 2017
Abstract In Brazil the knowledge about methicillin-resistant Staphylococcus aureus infection in cystic fibrosis patients is scarce. This study aimed to determine the incidence of respiratory tract colonization and the identification rates after a standardized treatment. A retrospective cohort was perform...

Síntesis de nanopartículas de ácido poliláctico cargadas con antibióticos y su actividad antibacteriana contra Escherichia coli O157:H7 y Staphylococcus aureus resistente a meticilina

Biomédica (Bogotá); 37 (1), 2017
Resumen Introducción: Las nanopartículas poliméricas constituyen una herramienta nanotecnológica que podría ayudar a combatir los microorganismos patógenos que han desarrollado resistencia a los antibióticos convencionales. Objetivo: Sintetizar nanopartículas de ácido poliláctico cargadas con...

Oxacillin magnetically targeted for the treatment of Methicillin-Resistant S. aureus infection in rats

Acta cir. bras; 32 (1), 2017
Abstract Purpose: To evaluate the effect of oxacillin bonded to magnetic nanoparticles in local infection model in rat. Methods: Twelve Wistar rats weighing 290±18g were randomly divided into four groups (n=6, each) and all rats had a magnet ring sutured on their right thighs. In the biodistribution g...

Molecular epidemiology of coagulase-negative bloodstream isolates: detection of Staphylococcus epidermidis ST2, ST7 and linezolid-resistant ST23

Braz. j. infect. dis; 20 (5), 2016
Abstract The mechanisms contributing to persistence of coagulase-negative staphylococci are diverse; to better understanding of their dynamics, the characterization of nosocomial isolates is needed. Our aim was to characterize phenotypic and molecular characteristics of Staphylococcus epidermidis and Sta...

Infecciones graves por Staphylococcus aureus: características clínicas, sensibilidad antibiótica y uso de antimicrobianos. Serie de casos

Arch. argent. pediatr; 112 (4), 2014
La aparición de infecciones por Staphylococcus aureus (SA) meticilino-resistente (MR) de la comunidad es un problema de salud pública de variable magnitud en diferentes áreas geográficas del mundo. El debate acerca del tratamiento antibiótico empírico inicial permanece abierto. Nuestro objetivo es ...
