Resistencia a la meticilina y producción de biopelícula en aislamientos clínicos de Staphylococcus aureus y Staphylococcus coagulasa negativa en México

Biomédica (Bogotá); 39 (3), 2019
Resumen Introducción. Las infecciones por Staphylococcus aureus y Staphylococcus coagulasa negativa multirresistentes a los antibióticos y asociadas con la atención en salud tienen un gran impacto epidemiológico por su alta morbimortalidad; además, se han relacionado con la formación de biopelícu...

Detection of some virulence factors genes in Staphylococcus aureus isolated from different clinical cases

Prensa méd. argent; 105 (2), 2019
Staphylococcus aureus is one of the most important pathogenic type to humans, and the most common species responsible for a wide range of diseases such as furuncles, various abscesses, wounds abscesses resulting from surgical operations, dermatitis, soft tissue inflammation, arthritis, bones inflammation...

Matrix-assisted laser desorption ionization-time of flight: a promising alternative method of identifying the major coagulase-negative Staphylococci species

Abstract INTRODUCTION. This study aimed to evaluate different methods for differentiation of species of coagulase-negative staphylococci (CoNS) that caused infections in hospitalized immunocompromised patients. METHODS. A total of 134 CoNS strains were characterized using four different methods. RES...

Characterization of Staphylococcus spp. strains in milk from buffaloes with mastitis in Brazil: the need to identify to species level to avoid misidentification

Mastitis is an inflammation of the mammary gland that affects dairy cattle worldwide causing economic losses. Coagulase-negative staphylococci (CNS) are the predominant cause of this type of infection. We have recently showed that coagulase-positive staphylococci could be misidentified. So, the aim of th...

Antimicrobial susceptibility profile and research of mec A and erm genes in coagulase-negative staphylococci isolated from platelet concentrates bags

Abstract In recent years, several studies have described the clinical impact of bacterial infection associated with transfusion of platelet concentrates (PCs). Among the blood components, PCs are responsible for the highest rates of bacterial contamination as well as septic transfusion reactions. We asse...

Qualidade microbiológica de pescado comercializado em feiras livres de Palmas - TO
Microbiological quality of fish marketed in Palmas - TO

Hig. aliment; 30 (262/263), 2016
O pescado é um dos alimentos mais suscetíveis à deterioração. O objetivo desse trabalho foi avaliar a qualidade microbiológica e temperatura da Caranha (Piaractus mesopotamicus) em 27 amostras, Tambaqui (Colossoma macropomum) em 22 amostras e Tucunaré (Cichla sp.) em 2 amostras, comercializados em...

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...

Empiric therapy with vancomycin in the neonatal intensive care unit: let's "get smart" globally!

Coagulase-negative staphylococci in Southern Brazil: looking toward its high diversity

Abstract: INTRODUCTION: Coagulase-negative staphylococci (CoNS) are the most prevalent pathogens in nosocomial infections and may serve as a reservoir of mobile genetic elements such as the staphylococcal cassette chromosome mec (SCCmec) encoding methicillin resistance. Molecular characterization of SC...

La resistencia a los antibióticos y la falta de interés de la industria farmacéutica

Infectio; 18 (2), 2014
La resistencia a los antibióticos aparece como consecuencia de mutaciones y de presiones de selección por el uso indiscriminado de estos medicamentos y se disemina rápidamente con alcance global. Esta diseminación se facilita por la poca higiene en los hospitales y por la mayor frecuencia en los viaj...
