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...

BACKGROUND Vancomycin-resistant (VR) Enterococcus faecium is increasingly found to colonize and infect hospitalized patients. Enterococci are frequently isolated from polymicrobial infections originating from the intestines. The impact of VR E. faecium on these infections and vice versa is not clear. METHODS Mice were intestinally colonized with VR E. faecium during oral vancomycin treatment;...

background enterococcus faecium is an important nosocomial pathogen and has developed resistance to multiple antibiotics, such as vancomycin. nitrofurantoin is active against e. faecium and e. faecalis, including vana- and vanb-positive isolates. objectives to investigate the role of rpob mutation in e. faecium. methods the growth rate and reactive oxygen species (ros) levels were determined. t...

BACKGROUND Virginiamycin use in poultry selects for Enterococcus faecium with cross-resistance to quinupristin-dalfopristin, a drug for vancomycin-resistant E. faecium in humans. We conducted an epidemiologic study of poultry exposures as risk factors for human carriage of quinupristin-dalfopristin-resistant E. faecium. METHODS Rectal or fecal samples for E. faecium testing were obtained from...

Little is known on the genetic relatedness and potential dissemination of particular enterococcal clones in Malaysia. We studied the antibiotic susceptibility profiles of Enterococcus faecium and Enterococcus faecalis and subjected them to pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST). E. faecium and E. faecalis displayed 27 and 30 pulsotypes, respectively, and 1...

Historically, most clinical microbiology laboratories report that 80 to 90% of enterococci are Enterococcus faecalis, whereas E. faecium accounts for 5 to 10% of isolates. At our medical center from 1993 to 2002, we evaluated the percentages of E. faecium among all enterococcal isolates and the percentages of E. faecium isolates that were vancomycin resistant. Over this 10-year period, the perc...

BACKGROUND Human skin is able to mount a fast response against invading microorganisms by the release of antimicrobial proteins such as the ribonuclease RNase 7. Because RNase 7 exhibits high activity against Enterococcus faecium the aim of this study was to further explore the role of RNase 7 in the cutaneous innate defense system against E. faecium. METHODOLOGY/PRINCIPAL FINDINGS Absolute q...

BACKGROUND AND PURPOSE Enterococcus faecium is a normal bowel commensal and lactic acid bacterium that is rarely found in the oral cavity. This study investigated whether a non-pathogenic and non-biofilm strain of E. faecium functioned as a probiotic strain toward biofilm formation by Streptococcus mutans, which is an etiological agent for dental caries. METHODS The effects of E. faecium on s...

The incidence of infections with Enterococcus faecium is increasing worldwide. TLRs have been implicated in the recognition of pathogens and the initiation of an adequate innate immune response. We here sought to determine the roles of MyD88, the common adaptor protein involved in TLR signaling, TLR2, TLR4, and CD14 in host defense against E. faecium peritonitis. MyD88 knockout (KO) mice demons...

Reasons for the rising clinical impact of the bacterium Enterococcus faecium include the species' rapid acquisition of adaptive genetic elements. Here, we focused on the impact of recombination on the evolution of E. faecium. We used the recently developed BratNextGen algorithm to detect recombinant regions in the core genome of 34 E. faecium strains, including three newly sequenced clinical st...
