• It is noteworthy that E. faecalis and E. faecium cause treatment to be increasing difficult because of their intrinsic and acquired resistance to many antibiotics. (frontiersin.org)
  • Platelet aggregation could be abolished by an IgG-specific proteinase (IdeS), by an antibody blocking FcRgammaIIa on platelets, or by preabsorption of plasma with an E. faecalis isolate. (lu.se)
  • Enterococci are well known to be particularly resistant to a variety of environmental stresses ( 9 - 11 ), properties that have been widely used as the basis of schemes to isolate or differentiate enterococci from other Gram-positive cocci. (pnas.org)
  • The fact that Enetrococcus faecalis can be resistant to a wide array of antibiotics must contribute to the proliferation of the organism. (livestrong.com)
  • These results indicate that platelet activation and aggregation by E. faecalis is dependent on both host and bacterial factors and that it may be involved in the pathogenesis of invasive disease with this organism. (lu.se)
  • Since Enterococcus spp is the second most common cause of Gram-positive blood stream infections in Brazil and that approximately 76% of all enterococcal infections are due to Enterococcus faecalis , we evaluated cases of bacteremia caused by this organism at the teaching hospital of the Universidade Estadual de Campinas (Unicamp), Campinas, São Paulo State (8). (scielo.br)
  • The determinant for the pheromone in E. faecalis FA2-2, designated cad , was found to encode a 309-amino-acid lipoprotein precursor with the last 8 residues of its 22-amino acid signal sequence representing the cAD1 moiety. (asm.org)
  • Independently, and at about the same time, Tomura et al (67), in Japan, reported on the transferability of a hemolysin/bacteriocin determinant in E. faecalis . (springer.com)
  • Enterococci grown in serum-supplemented broth adhere to Fg-coated surfaces, and inactivation in strain OG1RF of the gene encoding Fss2 resulted in reduced adherence, whilst complementation of the mutant restored full Fg adherence. (nih.gov)
  • E. faecalis is resistant to many commonly used antimicrobial agents (aminoglycosides, aztreonam, cephalosporins, clindamycin, the semisynthetic penicillins nafcillin and oxacillin, and trimethoprim-sulfamethoxazole). (wikipedia.org)
  • Primary amino acid sequence characteristics of the three Fg-binding E. faecalis MSCRAMMs and analysis of purified recombinant segments encompassing their predicted ligand-binding regions. (nih.gov)
  • Enterococcus faecalis biofilm traits and distribution characteristics in China have not been clarified. (frontiersin.org)
  • In root canal treatments, NaOCl and chlorhexidine (CHX) are used to fight E. faecalis before isolating the canal. (wikipedia.org)
  • However, recent studies determined that NaOCl or CHX showed low ability to eliminate E. faecalis. (wikipedia.org)
  • Structurally intact EfLTA purified from E. faecalis was treated with NaOCl at various concentrations and time periods. (ovid.com)
  • The mean diameters of the inhibition zones for E. faecalis were 2.8 mm (1% NaOCl), 5.4 mm (2.5% NaOCl), and 8.3 mm (5.25% NaOCl). (scielo.br)
  • In 2013, a combination of cold denaturation and NMR spectroscopy was used to show detailed insights into the unfolding of the E. faecalis homodimeric repressor protein CylR2. (wikipedia.org)
  • Because Enterococcus faecalis is normally found in the intestinal tract of people, it easily becomes a contamination problem in hospital and institutional settings. (livestrong.com)
  • We demonstrate that the commensal bacterium Enterococcus faecalis contributes to the pathogenesis of anastomotic leak through its capacity to degrade collagen and to activate tissue matrix metalloproteinase 9 (MMP9) in host intestinal tissues. (sciencemag.org)
  • When Enterococcus faecalis is grown of bacteriological agar that contains blood, it typically appears as small gray colonies that lack a zone of hemolyzed cells surrounding the colony. (livestrong.com)
  • Growth under hostile conditions such as the GI tract requires metabolic flexibility, and enterococci can catabolize various energy sources including ethanolamine ( 2 ). (pnas.org)
  • A high inhibitory effect on the metabolic activity of E. faecalis was detected when the microorganisms were incubated with 17% EDTA. (scielo.br)
  • Martial Jullien, Guy Thériault, Michel G Bergeron, and Denis Beauchamp, "Effect of Enterococcus faecalis Pyelonephritis on the Intracortical Accumulation Kinetics of Gentamicin in Rats," Canadian Journal of Infectious Diseases , vol. 1, no. 4, pp. 117-120, 1990. (hindawi.com)
  • Treating E. faecalis UTI's are usually easier to treat with antibiotics. (livestrong.com)
  • An E. faecalis mutant lacking PrkC grows at a wild-type rate in the absence of antimicrobial stress but exhibits enhanced sensitivity to cell-envelope-active compounds, including antibiotics that target cell-wall biogenesis and bile detergents. (pnas.org)
