Genealogy of family D, indicating the number and the genotypes of isolates for each member.

<p>The <i>hspA</i> and <i>glmM</i> alleles are designated H and G, respectively. The alleles are numbered according to the phylogenetic cluster to which they belong (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0002259#pone-0002259-g004" target="_blank">Fig 4</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0002259#pone-0002259-g005" target="_blank">5</a>). Lower case letters were assigned when alleles differed by point mutations. * name of the isolates studied on macroarrays. S, name of the strains defined by macro-arrays. Age of children is in brackets.
