PFGE profiles of type II isolates with vanA or vanB. The main type of VRE type II is in lane 1. The vanA and vanB groups share the same band differences compared to the bands for the main type (arrows). By comparing lane 1 to lane 4, it could be seen that patterns differ by one band if only the 10 largest bands are included in the analysis but by 4 bands if 16 bands were analyzed.
