Volatile sulfur compounds (VSCs) produced by oral anaerobes are the major compounds responsible for oral malodor. Enterococcus faecium WB2000 is recognized as an antiplaque probiotic bacterium. In this study, the effect of E. faecium WB2000 on VSC production by Porphyromonas gingivalis was evaluated, and the mechanism of inhibition of oral malodor was investigated. P. gingivalis ATCC 33277 was ...

background: to determine the species distribution, updated drug susceptibility patterns and genes conferring resistance in clini­cal vancomycin resistant enterococcal (vre) isolates. methods: clinical enterococcal isolates collected during 7 months, from september 2005 to april 2006 from hos­pitalized pa­tients and outpatients were studied. twenty five vre were isolated from 450 enterococci sam...

Enterococci are a major cause of health care-associated infections and account for approximately 10% of all bacteremias globally. The aim of this study was to determine the proportion of enterococcal bacteremia isolates in Australia that are antimicrobial resistant, with particular emphasis on susceptibility to ampicillin and the glycopeptides, and to characterize the molecular epidemiology of ...

Results We studied 841 patients, 21 of them (2.5 %) with an E. Faecium infection. No E. faecium vancomycin resistance was found. Patients with E. Faecium isolation were older (69.5 vs 64), infections had been acquired in the hospital, were surgical patients in higher proportion and had longer ICU stay (81 vs 44.3 % p 0.001 and 57.1 vs 27.5 % p 0.003 and 6 (3-11) vs 13 (6-25) p 0.001 respectivel...

Enterococcus faecium, a major cause of hospital-acquired infections, remains problematic because of its propensity to acquire resistance to vancomycin, which currently is considered first-line therapy. Here, we assess the evolution and resistance acquisition dynamics of E. faecium in a clinical context using a series of 132 bloodstream infection isolates from a single hospital. All isolates, of...

Four Enterococcus faecium strains isolated from fermented products were evaluated for potential use as probiotic strains. In addition to efaAfm gene, commonly found in E. faecium food isolates, none of the isolates possessed virulence genes and none had positive reactions for the production of tyramine, histamine, putrescine and cadaverine in the screening medium used. All of these four isolate...

Enterococcus faecium is an important multidrug-resistant nosocomial pathogen causing biofilm-mediated infections in patients with medical devices. Insight into E. faecium biofilm pathogenesis is pivotal for the development of new strategies to prevent and treat these infections. In several bacteria, a major autolysin is essential for extracellular DNA (eDNA) release in the biofilm matrix, contr...

Enterococcus faecium has recently emerged as a serious nosocomial pathogen. The prevalence and severity of enterococcal infections, the mortality rate from such infections, and the antibiotic resistance of enterococci are often species dependent. Since conventional biochemical methods fail to differentiate E. faecium from certain newly described enterococcal species, a PCR-based assay was devel...

Enterococcus faecium has become a nosocomial pathogen of major importance, causing infections that are difficult to treat owing to its multi-drug resistance. In particular, resistance to the β-lactam antibiotic ampicillin has become ubiquitous among clinical isolates. Mutations in the low-affinity penicillin binding protein PBP5 have previously been shown to be important for ampicillin resistan...
