Figure 3From: Horizontally acquired divergent O-antigen contributes to escape from cross-immunity in the classical bordetellaeSequence similarity across the classical bordetellae O-antigen loci compared to B. parapertussis 12822. Percent similarity of the O-antigen locus and flanking genes based on 12822 was plotted between 0% and 100% using zPicture [42]. Intergenic regions and coding regions were highlighted with red and blue, respectively. The genome-wide SNP tree was superimposed on the left.Back to article page
