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,

Whole‐Genome Sequence Profiling of Listeria innocua From Different Sources: Implications for Public Health

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
The studied strains, LIN_NWU_CNKT and LIN5_NWU_CNKT, exhibit invasiveness, pathogenicity, and MDR profiles. The isolation of these strains from food products and water underscores their significant public health implications, particularly in the context of the “One Health” concept.

Genomic Insights Into a Hospital‐Acquired High‐Risk Vancomycin‐Resistant Enterococcus faecium Outbreak in Guangdong, China

MicrobiologyOpen, Volume 15, Issue 2, April 2026.
We characterized a dominant ST80 clone responsible for a vancomycin‐resistant Enterococcus faecium outbreak in Chinese hospitals, revealing its close genetic ties to global lineages. A novel PCR method was developed for targeted surveillance of this high‐risk strain. ABSTRACT A comprehensive molecular epidemiological study was conducted on a vancomycin‐

Performance of three chromogenic VRE screening agars, two Etest® vancomycin protocols, and different microdilution methods in detecting vanB genotype Enterococcus faecium with varying vancomycin MICs [PDF]

, 2012
Frequencies of vanB-type Enterococcus faecium increased in Europe during the last years. VanB enterococci show various levels of vancomycin MICs even below the susceptible breakpoint challenging a reliable diagnostics.

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

Transferable, Plasmid-Mediated VanB-Type Glycopeptide Resistance in Enterococcus faecium [PDF]

Antimicrobial Agents and Chemotherapy, 1998
ABSTRACT An approximately 60-kb transferable, vanB -carrying plasmid has been identified in a clinical Enterococcus faecium strain. A similar plasmid has been observed in an unrelated E. faecium strain, suggesting that plasmid transfer of vanB

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
