Development of Improved Genetic Methods for Enterococcus Faecium
<p>Enterococcus faecium is a ubiquitous Gram-positive bacterium that has been recovered from the environment, food, and microbiota of mammals. Enterococcus faecium is widely recognized as an emerging public health threat with the rise of drug resistance and nosocomial infections. Antibiotic usage …

Wirkung von Enterococcus faecium auf den Organismus neonataler Hundewelpen
… with a lower share of E. coli, in higher Enterococcus counts and throughout lower shares of Cl. perfringens positive animals. These facts are as desirable for the maintenance of the intestinal eubiosis, as is the discovery of a higher average count on Lactobacillus spp. in the trail group. …

Molecular Basis of Cell Membrane Adaption Against Daptomycin in Enterococcus faecalis
… (Grein et al., 2020a; Müller et al., 2016a). Enterococcus faecalis has developed a sophisticated mechanism to avoid daptomycin killing by redistributing CM anionic phospholipids away from the septum. The CM changes are orchestrated by a three-component regulatory system, designated LiaFSR, …

Rectal culture screening for vancomycin-resistant enterococcus in chronic haemodialysis patients
Infection or colonisation with vancomycin-resistant enterococci (VRE) is common in chronic haemodialysis(HD) patients. However, there is limited information on the duration of VRE colonisation or on the reliability of consecutive negative rectal cultures to determine the clearance of VRE in chronic …

Identification et caractérisation de bactériocines produites par deux bactéries lactiques (Enterococcus faecium CWBI-B1430 et Enterococcus mundtii CWBI-B1431) isolées à partir de fromages frais artisanaux péruviens
… for Biotechnology Information). These were Enterococcus faecium CWBI-B1430 (accession number EF591817) and Enterococcus mundtii CWBI-B1431 (accession number EF591816). Two of the major factors concerned in a potential health risk associated with the genus Enterococcus were evaluated, and it …

Single cell analysis of bacterial communication and gene transfer by Enterococcus faecalis
Enterococcus faecalis is a commensal member of the gastrointestinal tract of animals including humans but is also an opportunistic pathogen and a major cause of healthcare-associated infections. Its pathogenicity is thought to arise in immunocompromised people and after infection, treatment is …

MODELING REORGANIZATION OF PCF10-INDUCED COMPLEX STRUCTURES IN ENTEROCOCCUS FAECALIS UNDER ERYTHROMYCIN TREATMENT
… In this dissertation, we look at the bacterium Enterococcus faecalis. E. faecalis is a gram-positive, commensal bacterium commonly found in the human gastrointestinal tract. Generally, commensal E. faecalis does not negatively impact human health, but pathogenic features can be acquired by this …

Mecanismos de resistencia a antibióticos macrólidos, lincosamidas y estreptograminas en streptococcus y enterococcus
… (MLS) resistance mechanisms in Streptococcus and Enterococcus in La Rioja, from 1996 to 2001. Distribution of erythromcyin resistance phenotypes and involved mechanisms were studied for both genera, as well as temporary evolution and clonal diversity for erythromycin-resistant Streptococcus …

Multiple Posttranscriptional Regulatory Features Control Expression of Ethanolamine Utilization Genes In Enterococcus Faecalis
<p> <p><em>Enterococcus faecalis</em> is a Gram-positive bacterium that lives as a commensal organism in the mammalian gastrointestinal tract, but can behave as an opportunistic pathogen. Our lab discovered that mutation of the <em>eutK</em> gene attenuates virulence of <em>E. faecalis</em> in the …

The antimicrobial effect of orange, lemon and bergamot esential oils against Enterococcus sp
… activity against vancomycin-sensitive Enterococcus faecium and Enterococcus faecalis. Lemon essential oil alone or blended and orange EO alone were not as effective as citral or linalool alone or bergamot blends with inhibition diameters of > 9cm. The ranges established for differences …

Development of a Flow Cytometry Method for the Identification and Enumeration of Enterococcus faecalis
<p>A multi-color flow cytometry method coupled with fluorescent staining was developed to detect and quantify <em>E. faecalis</em> concentrations in coastal waters as an alternative to the traditional membrane filtration method. The developed method was used to characterize <em>E. faecalis …

Assessing the Presence of Antibiotic-Resistant Enterococcus in Reclaimed Water Used for Spray Irrigation
… and antimicrobial susceptibilities of Enterococcus spp.--an important opportunistic pathogen that remains a leading cause of nosocomial infections--in reclaimed water used for spray irrigation (SI). A total of 48 wastewater effluent and SI samples were collected in 2009 and 2010 from …

Microbial glucosinolate metabolism: Characterization of Enterococcus faecalis XL1 and functional analysis of a GH4 enzyme
… underlying GSL hydrolysis, focusing primarily on Enterococcus faecalis XL1, a gut isolate obtained from broccoli-fed rats. Whole-genome sequencing and gene expression analyses identified multiple β-glucoside phosphotransferase system (PTS) transporters and glycoside hydrolases (GHs) responsive to …

Use of electromagnetic stimulation on an Enterococcus faecalis biofilm in root canal treated teeth in vitro
… effect of EMS against an established biofilm of Enterococcus faecalis. Materials and Methods: Single rooted teeth were cut to a standardized length (12 mm) and instrumented with a 45.05 Wave One Gold reciprocating file. Specimens were sterilized and inoculated with E. faecalis, which grew for two …
