High Rates of Fecal Carriage of Nonenterococcal vanB in both Children and Adults [PDF]

Antimicrobial Agents and Chemotherapy, 2008
ABSTRACT We examined the rate of fecal carriage of vanB in the absence of cultivable vancomycin-resistant enterococci in three distinct populations (children, community adults, and hemodialysis patients). Nonenterococcal vanB carriage was similarly high in hemodialysis patients (45%)

Mechanism of VanB Phenotype in Vancomycin-Resistant Enterococci carrying vanA gene [PDF]

Annals of Laboratory Medicine, 2006
Recently, vancomycin-resistant enterococci (VRE) with the vanA genotype that are susceptible to teicoplanin have been described in Japan, Taiwan, and Korea. The investigators suggested three point mutations in the putative sensor domain of vanS or impairment of accessory proteins VanY and VanZ as an explanation for the VanB phenotype-vanA genotype VRE.

One Health Surveillance of Antimicrobial Resistance in the Eastern Mediterranean: The Blackchin Guitarfish as a Case Study

GeoHealth, Volume 10, Issue 4, April 2026.
Abstract Antimicrobial resistance (AMR) poses a global One Health challenge, linking human, animal, and environmental health. Marine environments and organisms are increasingly recognized as reservoirs of antimicrobial‐resistant bacteria and mobile genetic elements.

Peptidoglycan structure of Enterococcus faecium expressing vancomycin resistance of the VanB type [PDF]

Biochemical Journal, 1996
Resistance to glycopeptide antibiotics in enterococci is due to the synthesis of UDP-MurNAc-tetrapeptide-D-lactate (where Mur is muramic acid) replacing the normal UDP-MurNAc-pentapeptide precursor. The peptidoglycan structures of an inducible VanB-type glycopeptide-resistant Enterococcus faecium, D366, and its constitutively resistant derivative, MT9,

Ecologically‐Valid Emotion Signatures Enhance Mood Disorder Diagnostics

Advanced Science, Volume 13, Issue 13, 3 March 2026.
This study identifies ecologically‐valid Divergent Emotional Functional Networks (DEFN), derived from dynamic functional connectivity during naturalistic movie watching. The DEFN reliably enhances diagnostic accuracy for mood disorders, including major depressive and bipolar disorders, demonstrating strong reproducibility across demographic factors and

Methicillin and vancomycin resistance in coagulase-negative Staphylococci isolated from the nostrils of hospitalized patients

Journal of Infection in Developing Countries, 2020
Introduction: Nasal colonization by coagulase-negative Staphylococci (CoNS) play an important role in nosocomial infections. This study aims to determine antibiotics susceptibility pattern and molecular screening of methicillin- and vancomycin-resistant

Do We Need to Worry About Staphylococcus epidermidis ST0409KOC, a Cheese‐Isolated Strain With Bacteriocinogenic Properties?

Molecular Nutrition &Food Research, Volume 70, Issue 1, January 2026.
Bacteriocinogenic Staphylococcus epidermidis ST0409KOC was isolated from cheese and characterized as bacteriocin‐producing with strong activity versus Listeria monocytogenes and other pathogens. S. epidermidis ST0409KOC can be considered a safe strain regarding its virulence genetic background, presenting only a single virulence gene of IS257 among the

International Survey on Antibiotic Prophylaxis Approaches for Solid Organ Transplant Recipients and Donors Colonized With Multidrug‐Resistant Organisms

Transplant Infectious Disease, Volume 28, Issue 1, January/February 2026.
ABSTRACT Background Multidrug‐resistant organism colonization and infections cause significant morbidity and mortality in solid organ transplantation, affecting the perioperative antibiotic management. Yet, international practices for screening and antibiotic prophylaxis in colonized donors and recipients remain poorly defined.
