Antimicrobial activity of Tetradenia riparialeaf essential oil

Food spoilage is a widely neglected problem and the constant use of synthetic fungicides could develop resistant fungi. The objective of this study was to evaluate the chemical composition and antimicrobial activity of Tetradenia riparialeaf essential oil against foodborne disease microor...

Perfil epidemiológico de Staphylococcus spp. isolados de hemoculturas de pacientes internados em um hospital de atenção terciária da rede pública do Ceará

Staphylococcus spp. vem ganhando destaque em infecções na corrente sanguínea (ICS), apresentando alta prevalência, multirresistência e considerável poder de letalidade. O presente estudo teve como objetivo analisar a prevalência e traçar o perfil de sensibilidade das espécies de Staphylococcus...

Antimicrobial resistance evaluation of bacteria isolated from infections in small animals in the Umuarama region, Paraná

Pesqui. vet. bras; 40 (10), 2020
Bacterial resistance is shown to be an inevitable side effect due to the excessive use of antibiotics, becoming a significant concern worldwide. Knowledge of regional bacterial resistance profiles enables the development of site-specific infection control practices, making conscious and moderate use of c...

Coagulase-negative staphylococci: a 20-year study on the antimicrobial resistance profile of blood culture isolates from a teaching hospital

Braz. j. infect. dis; 24 (2), 2020
ABSTRACT The increasing rates of nosocomial infection associated with coagulase-negative staphylococci (CoNS) were the rationale for this study, aiming to categorize oxacillin-resistant CoNS species recovered from blood culture specimens of inpatients at the UNESP Hospital das Clínicas in Botucatu, Braz...

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...

Identification and antimicrobial suceptibility profile of bacteria causing bovine mastitis from dairy farms in Pelotas, Rio Grande do Sul

Braz. j. biol; 78 (4), 2018
Abstract Mastitis is an inflammatory process of the udder tissue caused mainly by the bacteria Staphylococcus aureus. The indiscriminate use of antibiotics fosters conditions that favor the selection of resistant microorganisms, suppressing at the same time susceptible forms, causing a serious problem in...

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...

Presencia de estafilococos coagulasa positiva ambientales, su relación clonal, factores de resistencia y habilidad para formar biopelícula
Presence of environmental coagulase-positive staphylococci, their clonal relationship, resistance factors and ability to form biofilm

Rev. argent. microbiol; 49 (1), 2017
Coagulase-positive staphylococci (CoPS) are opportunistic pathogens carrying various mechanisms of resistance that have a large number of virulence factors, and whose ability to induce illness is associated with the host. This study aimed to investigate the presence of environmental coagulase-positive st...

Biofilm inhibition activity of traditional medicinal plants from Northwestern Argentina against native pathogen and environmental microorganisms

Abstract: INTRODUCTION: Plants have been commonly used in popular medicine of most cultures for the treatment of disease. The in vitro antimicrobial activity of certain Argentine plants used in traditional medicine has been reported. The aim of this study was to investigate the antimicrobial, anti-biof...

Serum levels of vancomycin: is there a prediction using doses in mg/kg/day or m2/day for neonates?

Braz. j. infect. dis; 20 (5), 2016
Abstract Coagulase-negative Staphylococcus has been identified as the main nosocomial agent of neonatal late-onset sepsis. However, based on the pharmacokinetics and erratic distribution of vancomycin, recommended empirical dose is not ideal, due to the inappropriate serum levels that have been measured ...
