Bayesian unrooted phylogenetic tree of blpH alleles. The outer ring shows the number of 4096 genomes with each blpH allele, color-coded by their co-occurring BlpC signal and on a log scale. The inner ring denotes the blpH clade type, and recombination events within blpH are shown as solid green lines. Internal nodes show the posterior probabilities of clades; we collapsed clades with <90% posterior probability
