Vancomycin-resistant vanB-type Enterococcus faecium isolates expressing varying levels of vancomycin resistance and being highly prevalent among neonatal patients in a single ICU

Antimicrobial Resistance and Infection Control, 2012
Background Vancomycin-resistant isolates of E. faecalis and E. faecium are of special concern and patients at risk of acquiring a VRE colonization/infection include also intensively-cared neonates. We describe here an ongoing high prevalence of VanB type

Real-Time PCR Assay for Rapid and Simultaneous Detection of vanA and vanB Genes in Clinical Strains

Diagnostics, 2021
Here, we develop a robust and sensitive real-time PCR assay which allows the simultaneous detection of vanA and vanB genes using common primers. The system was designed using the Primer3 online software.

Investigation of the introduction and dissemination of vanB Enterococcus faecium in the Capital Region of Denmark and development of a rapid and accurate clone-specific vanB E. faecium PCR

Journal of Antimicrobial Chemotherapy, 2021
Abstract Background During 2018–19, an increase of vanB vancomycin-resistant Enterococcus faecium (VREfm) was observed in the Capital Region of Denmark. vanA/vanB PCR performed directly on rectal swabs is accurate in detection of vanA; however, the positive predictive value for vanB-positive samples ...

Emergence and characterisation of vanB vancomycin-resistant Enterococcus faecalis in Rio de Janeiro, Brazil

Memorias do Instituto Oswaldo Cruz, 2012
Here we describe the detection and characterisation of three isolates of vancomycin-resistant VanB-type Enterococcus faecalis. Sequence analysis suggested that these isolates harboured the vanB1 gene.

Molecular Characterization of vanB Elements in Naturally Occurring Gut Anaerobes [PDF]

Antimicrobial Agents and Chemotherapy, 2005
ABSTRACT Previously, we reported the isolation of 10 vancomycin-resistant gram-positive anaerobic bacilli carrying the vanB ligase gene from nine hemodialysis patients (S. A. Ballard et al., Antimicrob. Agents Chemother. 49:77-81, 2005; T. P. Stinear et al., Lancet 357:855-856, 2001). In the present study,

Antimicrobial Resistance at the Human–Animal–Environment Interface: A One Health Perspective on Drivers, Transmission, and Public Health Responses

Health Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background Antimicrobial resistance (AMR) is a global health threat driven by interconnected antimicrobial use and environmental pressures across human, animal, and ecological systems. This review synthesizes current evidence on the major drivers, transmission pathways, reservoirs, surveillance challenges, and public health responses ...

Comparison of Three PCR Primer Sets for Identification of vanB Gene Carriage in Feces and Correlation with Carriage of Vancomycin-Resistant Enterococci: Interference by vanB -Containing Anaerobic Bacilli [PDF]

Antimicrobial Agents and Chemotherapy, 2005
ABSTRACT We assessed the sensitivities and specificities of three previously described PCR primers on enrichment broth cultures of feces for the accurate detection of fecal carriage of vancomycin-resistant enterococci (VRE). In addition, we investigated specimens that were vanB PCR positive but VRE culture
