Figure 2.

Presence and divergence of PAI genes (123 of 129 open reading frames represented on the microarray) in nine E. faecalis baby isolates, as detected by CGH. Genes PAIef**** correspond to EF**** genes in the PAI of strain MMH594 [25]. Putative enterococcal virulence genes located on the PAI include aggregation substance (agg; EF0485), cytolysin (cyl; EF0523–27 + PAIef0047–49) and enterococcal surface protein (esp; PAIef0056). Dark gray = present, light gray = divergent.
