Characterization of vancomycin resistance mechanisms in Enterococcus faecium isolates from a Brazilian tertiary hospital

Background and Objectives: Vancomycin-resistant Enterococcus faecium (VREf) is an opportunistic pathogen responsible for hospital infections, characterized by increasing prevalence and a lack of comprehensive epidemiological studies. We aimed to assess the occurrence of VREf and vancomycin resistance gen...

Enterococcus faecium M7AN10 probiótico em matriz alimentar para cães

Vet. zootec; 31 (), 2024
Probióticos são capazes de melhorar o equilíbrio da microbiota intestinal, trazendo benefícios ao hospedeiro. Atualmente no mercado há poucas opções de alimentos, com probióticos em sua composição, destinados a cães e gatos. Portanto, o objetivo deste trabalho foi desenvolver uma matriz alimen...

Significant production of vanillin and in vitro amplification of ech gene in local bacterial isolates

Braz. j. biol; 83 (), 2023
Abstract Vanillin is the major component which is responsible for flavor and aroma of vanilla extract and is produced by 3 ways: natural extraction from vanilla plant, chemical synthesis and from microbial transformation. Current research was aimed to study bacterial production of vanillin from native na...

Bacteriemia por Enterococcus faeciumresistente a daptomicina
Daptomycin-resistant enterococcus faecium bacteremia

Actual. SIDA. infectol; 30 (110), 2022
La aparición de cepas de enterococos resistentes a daptomicina es un tema de preocupación clínica y epidemiológica en años recientes. Se presenta el caso de un paciente de 50 años con antecedente de artritis reumatoide e inmunosupresión crónica hospitalizado ...

Uso compasional de tigeciclina intraventricular en pacientes con ventriculitis causada por Enterococcus faecium. Reporte de seis casos pediátricos

Infectio; 24 (3), 2020
Introducción: La Tigeciclina es un fármaco de uso restringido en pediatría. El uso de este antibiótico por vía intraventricular es una decisión de uso compasivo en casos de bacterias altamente resistentes, y para los casos en que no exista otra alternativa. Caso clínico: Se presenta seis casos ...

Hallazgos microbiológicos y susceptibilidad antimicrobiana en cirugía abdominal de urgencia

Rev. cir. (Impr.); 72 (3), 2020
Resumen Introducción: Es importante mantener programas de vigilancia bacteriana para disminuir resistencia y definir esquemas farmacológicos adecuados. Los pacientes con abdomen agudo representan un grupo microbiológico especial. Objetivos: Hacer una revisión de agentes patógenos en pacientes adul...

Antimicrobial resistance and antibiotic consumption in Mexican hospitals

Salud pública Méx; 62 (1), 2020
Abstract: Objective: To establish the current situation of antimicrobial resistance and antibiotic consumption in Mexican hospitals. Materials and methods: Antimicrobial susceptibility data from blood and urine isolates were collected. Defined daily dose (DDD) of antibiotic consumption/100 occupied b...

Antibacterial Activity of Sophorolipids from Candida bombicola Against Human Pathogens

Abstract Sophorolipids are glycolipids that have natural antimicrobial properties and present great potential in the pharmaceutical field. The present study aimed to produce sophorolipids from Candida bombicola using a chicken fat-based medium and evaluate the antimicrobial activity against Gram-negative...

Frequency of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPRs) in non-clinical Enterococcus faecalis and Enterococcus faecium strains

Braz. j. biol; 79 (3), 2019
Abstract The fidelity of the genomes is defended by mechanism known as Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) systems. Three Type II CRISPR systems (CRISPR1- cas, CRISPR2 and CRISPR3-cas) have been identified in enterococci isolates from clinical and environmental samples. Th...

Resistencia a los β -lactámicos en enterococos
Resistance to β-lactams in enterococci

Rev. argent. microbiol; 51 (2), 2019
Enterococci are intrinsically resistant to several antimicrobial classes and show a great ability to acquire new mechanisms of resistance. Resistance to β-lactam antibiotics is a major concern because these drugs either alone or in combination are commonly used for the treatment of enterococcal infe...
