Distribution of fimbrial operons. Shown is the presence or absence of the fimbria-encoding operons. The phylogeny at the top uses the same colors as Fig. 1 for the different subclades. Positive hits had at least 80% nucleotide identity for greater than 75% of the genes in the operon, using the VFDB as a reference. A positive hit is indicated in green with no respect to sequence identity.
