Figure 6From: Horizontally acquired divergent O-antigen contributes to escape from cross-immunity in the classical bordetellaePhylogenetic trees for the classical bordetellae O-antigen loci. Phylogenetic trees were constructed by maximum likelihood method with 1,000 bootstrap replicates with individual gene sequences in the locus. Four representative (A: wbmA, B: wbmE, C: wbmN, and D: wbmZ) of similar phylogenetic trees were presented in this figure.Back to article page
