The relative importance of human and animal sources of vancomycin-resistant Enterococcus faecium in immunocompromised patients in hospital
Enterococcus faecium is a leading cause of hospital-acquired infection, disproportionally affecting immunocompromised and critically ill patients. Despite infection control measures, rates of vancomycin-resistant E. faecium (VREfm) bacteraemias have failed to decline in the United Kingdom, and …

Analogues of Nitrofuran Antibiotics are Potent GroEL/ES Pro-drug Inhibitors with Efficacy against Enterococcus Faecium, Staphylococcus Aureus, and Escherichia Coli
In 2019, the ESKAPE pathogens were highlighted by the World Health Organization as some of the most prominent threats to human health, capable of developing significant antibiotic resistance. These pathogens contribute to over 2 million annual infections and ~23,000 annual deaths in the U.S. In …

Impacts of inoculation strategy on survival of Salmonella enterica and Enterococcus faecium at low water activity on dry peppercorn and cumin seeds
… Salmonella enterica and its proposed surrogate, Enterococcus faecium NRRL B-2385, on the whole black peppercorns and cumin seeds was examined. Three liquid inoculation methods (biofilm-inclusion, agar-grown, broth-grown) for Salmonella enterica and surrogate Enterococcus faecium and one dry …

Determination of the occurrence, virulence genes, and antimicrobial resistance profiles of enterococcus faecalis and enterococcus faecium isolated from poultry of Chongwe, Lusaka, Kitwe, and Ndola districts, farmworkers from the Copperbelt province poultry farms and clinical specimens from Kitwe teaching hospital in Zambia.
Enterococcus has great genetic plasticity and is highly versatile, hence does not only acquire and express mobile genetic elements (MGEs) but also disseminates them to pathogenic and non-pathogenic species of the same or of different genera. As such, it has been associated with various clinical …

Library Screening and Focused Multiomics of Antibacterial Action on Vancomycin-Resistant Enterococci faecium
… target for many antibiotics to inhibit bacteria. Enterococcus species are gram-positive bacteria of the intestine in humans and animals that can lead to problematic infections of the gastrointestinal tract and the soft tissues. Vancomycin has been one of most important agents for the treatment of …
