PCR-HRMA difference plots of VRE and VSE E faecalis and E faecium generated against B fragilis using V1 primer set. Difference curve plots for (A) VSE (NCTC 77, NCIMB 2699) and (B) vanA/B VRE (ATCC 19434, ATCC 51299, ATCC 29212) standard strains of E faecalis and E faecium. Each assay contained 250 pg of bacterial DNA. B fragilis was also included as the reference organism for generating VRE/VSE difference curves (plots). B fragilis amplifies with the same efficiency as the E faecalis and E faecium strains.
