Background: Enterococci have emerged as a major cause of nosocomial infections and within this group, Enterococcus faecalis and Enterococcus faecium cause the majority of human and livestock enterococcal infections. In this article, we tried to determine antibiotics and metals resistance patterns of E. faecalis and E. faecium strains. Methods: One hundred sixty different strains of E. faecalis...

The gene encoding mature enterocin P (EntP), an antimicrobial peptide from Enterococcus faecium P13, was cloned into the pPICZalphaA expression vector to generate plasmid pJC31. This plasmid was integrated into the genome of P. pastoris X-33, and EntP was heterologously secreted from the recombinant P. pastoris X-33t1 derivative at a higher production and antagonistic activity than from E. faec...

Enterococcus faecium is an opportunistic human pathogen, found widely in the human gastrointestinal tract, and can also be isolated from a variety of plants, animals, insects, and other environmental sources. Here, we present the fine draft genome sequence of E. faecium LCT-EF90.

The space environment has been shown to affect microbes by altering various features, including morphology, growth rate, metabolism, virulence, drug resistance, and gene expression and mutation. Here we present the draft genome sequence of the Enterococcus faecium strain LCT-EF258, derived from the E. faecium strain CGMCC 1.1736, which was exposed to 17-day space flight.

High-dose daptomycin (DAP) therapy failed in a neutropenic patient with bloodstream infection caused by a DAP-susceptible Enterococcus faecium (minimum inhibitory concentration, 3 µg/mL) harboring genetic changes associated with DAP resistance, with persistent bacteremia and selection of additional resistances. Daptomycin monotherapy should be used cautiously against DAP-susceptible E. faecium ...

Enterococci are used as starter and probiotic cultures in foods, and they occur as natural food contaminants. The genus Enterococcus is of increased significance as a cause of nosocomial infections, and this trend is exacerbated by the development of antibiotic resistance. In this study, we investigated the incidence of known virulence determinants in starter, food, and medical strains of Enter...

BACKGROUND Enterococcus faecium has received increased attention, primarily due to the emergence of vancomycin resistance. The purpose of this investigation was to study the epidemiological characteristics of vancomycin-resistant E faecium (VRE) bacteremia and to determine the clinical impact of vancomycin resistance on the outcome of patients with this infection. METHODS We retrospectively a...

To determine patterns of antimicrobial susceptibility among enterococci and to assess molecular characteristics of vancomycin-resistant enterococci, 157 clinical blood isolates of enterococci from 10 hospitals in Cincinnati, Ohio, were prospectively collected during a 6-month period from February to July 1995. The isolates included 108 (69%) E. faecalis isolates, 46 (29%) E. faecium isolates, a...

The occurrence of resistance to the streptogramin quinupristin-dalfopristin in Enterococcus faecium isolates from chickens on the Eastern Seaboard, was evaluated. Quinupristin-dalfopristin resistance was found in 51 to 78% of E. faecium isolates from the food production environment. The high level of resistance in this organism suggests that this reservoir of resistance may compromise the thera...

Vancomycin-resistant Enterococcus faecium has emerged as a multidrug-resistant pathogen in hospital settings. Here, we present the draft genome sequence of a high-level vancomycin-resistant strain, E. faecium ATCC 51559, which is employed as a standard laboratory vanA genotype-positive control strain for clinical and laboratory studies.
