Prevalence of putative virulence genes.

a<p>The genes <i>acm</i>, <i>pilA</i>, <i>pilB</i> and <i>sagA</i> are prevalent among all <i>E. faecium</i> strains; the genes <i>EfmE4452_1561</i> and <i>EfmE4452_1565</i> are uniquely present in community ARE isolates (this paper). All other genes are specifically enriched among hospital isolates <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030319#pone.0030319-Willems1" target="_blank">[5]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030319#pone.0030319-Leavis1" target="_blank">[7]</a>–<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030319#pone.0030319-Willems3" target="_blank">[8]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030319#pone.0030319-Heikens1" target="_blank">[18]</a>–<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030319#pone.0030319-Nallapareddy1" target="_blank">[19]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0030319#pone.0030319-Hendrickx2" target="_blank">[52]</a>.</p>b<p>Source of the isolates carrying a particular gene: D = dog; C = cat; H = human.
