The relatedness among 91 Enterococcus strains representing all validly described species was investigated by comparing a 1,102-bp fragment of atpA, the gene encoding the alpha subunit of ATP synthase. The relationships observed were in agreement with the phylogeny inferred from 16S rRNA gene sequence analysis. However, atpA gene sequences were much more discriminatory than 16S rRNA for species ...

[email protected] Gut microbiota play an important roles in induction of various cellular responses, including cytokine production. In this work, we examined the involvement of four intestinal strains in induction of the cytokine response (the relative expression of TNF-α, IL-6, and IL-8) in intestinal epithelial cells. Caco-2 cells were treated with cell-free supernatants (CFS) of four intestin...

enterococcus and lactococcus are gram-positive cocci that often occur in pairs ( diplococci ) or short chains, and are difficult to differentiate from streptococci on physical characteristics alone. enterococcus faecium because have concern antibiotic resistant, consider difficult as probiotic. the results of an assay show that a probiotic e. faecium strain might be a potential recipient of van...

Enterococcus raffinosus, a non-faecalis and non-faecium enterococcus, rarely causes infections in humans. We describe the first reported case of primary bacterial endocarditis caused by E. raffinosus, with a review of the literature.

The presented study aims at analyzing an increasing prevalence of vancomycin-resistant enterococci (VRE) isolated from various kinds of clinical material obtained from patients in the Department of Hemato-oncology (DHO), University Hospital in Olomouc, Czech Republic. Between January 1 and March 31, 2005, enterococci were isolated by standard microbiological procedures using both clinical mater...

We report here the complete genome sequence of Enterococcus faecium strain ICIS 96, which was isolated from the feces of a horse. Bacteriological characterization of strain ICIS 96 revealed the absence of pathogenicity factors, while its spectrum of antagonistic activity was found to be broad, having activities associated with both Gram-positive and Gram-negative bacteria. Analysis of the E. fa...

BACKGROUND Enterococcus faecium is a multi-resistant nosocomial pathogen causing infection in debilitated patients. Vancomycin-resistant enterococcus faecium (VREfm) are a major concern and increased dramatically worldwide especially in hospitals environment. The current study focused on determining the high prevalence and distribution patterns of antibiotic resistance and also its genetic link...

Despite the increasing importance of Enterococcus as opportunistic pathogens, their virulence factors are still poorly understood. This study determines the frequency of virulence factors in clinical and commensal Enterococcus isolates from inpatients in Porto Alegre, Brazil. Fifty Enterococcus isolates were analysed and the presence of the gelE, asa1 and esp genes was determined. Gelatinase ac...

background and aims. enterococci are among resistant microorganisms to antibiotics and are responsible for some of acute gingival infections. this study aimed at molecular evaluation of gentamicin-resistant enterococcus species and determining the resistance genes. materials and methods. clinical samples were cultured on bhi medium and enterococci were isolated by specific methods and antibiogr...
