Isolation, Enumeration and Identification of Enterococci
… has been a steady increase of interest in the enterococci, members of the genus Streptococci, as indicators. |It is still debatable whether the coliforms or the enterococci are better indicators of contamination in food and water. However, there is a definite trend toward the use of the …

Molecular Mechanisms of Antimicrobial Resistance In Multi-Drug Resistant Enterococci
… is a major global public health threat. Enterococci are recalcitrant, nosocomial pathogens that can be intrinsically resistant to valuable antibiotics, like beta-lactams, or evolve resistance to all existing antimicrobials. The LiaFSR system regulates resistance to cell membrane (CM) …

Characterizing the Persistence of Sewage Enterococci in Mississippi Coastal Waters
<p>Enterococci are microbiological indicators of marine recreation water quality.<br />Their reliability as fecal indicators is questioned as they are shown to persist in the environment. Multiple laboratory studies on their persistence have been done but few under natural environmental conditions. …

Optimal Control Applied to a Mathematical Model for Vancomycin-Resistant Enterococci
Enterococci bacteria that cannot be treated effectively with the antibiotic vancomycin are termed Vancomycin-Resistant Enterococci (VRE). In this thesis, we develop a mathematical framework for determining optimal strategies for prevention and treatment of VRE in an Intensive Care Unit (ICU). A …

Molecular Characterization of Vancomycin-resistant Enterococci from Clinical and Surveillance Specimens
BACKGROUND: Vancomycin-resistant enterococci(VRE) were first detected in Europe in 1986, and have been isolated from hospitalized patients worldwide. VanA resistance, characterized by high level resistance to vancomycin and teicoplanin, is the most prevalent in clinical enterococcal isolates. To …

Repurposing Antibacterial Compounds and Natural Products to Combat Vancomycin-Resistant Enterococci
Antibiotic resistance is one of the greatest threats to modern medicine, leaving clinicians with shrinking treatment options for life-threatening infections. Among the most concerning pathogens are vancomycin-resistant Enterococcus (VRE), which causes serious bloodstream, urinary tract, and wound …

Detection of Vancomycin resistant Enterococci from clinical specimens at University Teaching Hospitals
Enterococci are commensal gram-positive bacteria in the gastrointestinal tract of humans. They have emerged as important nosocomial pathogens due to their ability to acquire and confer antimicrobial resistance genes, hence making management of infections due to Enterococcus species difficult. …

Library Screening and Focused Multiomics of Antibacterial Action on Vancomycin-Resistant Enterococci faecium
Antimicrobial resistance is a major public health threat, and there is an urgent need for new strategies to address this issue. In a gram-positive bacteria, the peptidoglycan layer is thick as compared to gram negatives and is made up of peptide like polysaccharide chains. This peptidoglycan layer …

Towards the post-antibiotic era: The role of antibiotic resistant enterococci in different sources
… la presenza e la struttura della popolazione enterococcica AR sia in matrici alimentari sia ambientali. In dettaglio, sono stati presi in considerazione due formaggi siciliani (Capitolo 1) e un impianto di depurazione urbano (Capitolo 2). Ad oggi, questa rappresenta la prima evidenza …

Enterococci and its enterocins as an alternative to antibiotics in poultry affected by necrotic enteritis
… of C. perfringens provide a good approach. Enterococci are characterized by the production of bacteriocins (enterocins) and can therefore be used for this purpose. However, these genera often contain virulence factors and antibiotic resistance mechanisms. Hence, due to their duality as …

ANTIMICROBIAL CHARACTERIZATION AND THERAPEUTIC APPLICATIONS OF NOVEL SYNTHETIC THIAZOLE COMPOUNDS AGAINST MULTIDRUG-RESISTANT STAPHYLOCOCCI AND ENTEROCOCCI
… aureus (MRSA) and vancomycin-resistant enterococci (VRE), has limited the efficacy of several classes of antibiotics. Compounding this problem further is that many large pharmaceutical companies have left the field of antibacterial drug discovery given the high cost of innovation and low …

Molecular Characteristics and Dissemination Mechanism of Vancomycin-Resistant Enterococci: A Tertiary vs. Non-Tertiary Health Care Hospitals
Vancomycin-resistant enterococci (VRE) have been endemic in Korea as a nosocomial pathogen. The aim of this study was to examine genetic relatedness and dissemination mechanism by comparative analysis of the antimicrobial and biomolecular characteristics of VRE isolates from tertiary and …

Overexpression, purification and ligand interaction studies of intact membrane sensory kinases from enterococci: towards agonist and antagonist screening
… in controlling antibiotic resistances in enterococci. Enterococci are amongst the most significant agents of nosocomial infections in the UK. The present study involved an investigation of two membrane sensor kinases known to be involved in antibiotic resistance in enterococci: (1) VanSA, …

Microbial risk assessment for recreational use of the Kranji Reservoir, Singapore
… the shore. The samples were then analyzed for Enterococci concentrations using a most probable number method. The measured geometric mean concentrations found during the field campaign were 13.3 Enterococci colony forming units (CFU) per 100 ml water and 1400 Enterococci CFU per gram sediment. …
