Impact of elements containing glycopeptide resistance genes on expression of virulence in Enterococcus faecalis peritonitis: a pilot study with rats.

PMID 12709322 · 2003

The study investigated the impact of glycopeptide resistance genes vanA and vanB on the virulence of Enterococcus faecalis in a rat peritonitis model. Both vanA and vanB conferred resistance to vancomycin.

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.

PMID 15616278 · 2005

The study evaluated PCR primer sets for detecting the vanB gene in fecal samples and found that vanB-containing anaerobic bacilli can cause false positives for vancomycin-resistant enterococci (VRE).
