Gene content variation and sequence polymorphism in fimbriae genes. Strain groups are color coded according to the tree topology shown in Fig. 2. For each probe, the sequenced strain from which it was amplified is listed, as well as the percent sequence identity of the probe to each of the three sequenced genomes. The color scale and symbols are as in Fig. 1.
