Clustering of H. influenzae and H. haemolyticus LicD alleles. The major clusters of H. influenzae (blue dots) and H. haemolyticus (red dots) strains are labeled by their predicted allele (LicDI, LicDIII, and LicDIV) and prototype LicD alleles from H. influenzae strains are shown for each cluster (black dots, E1a is partially hidden). The LicD protein of N. lactamica is the out-group for the analysis (green triangle).
