Figure 1.

Comparative genome content of eleven classical Bordetellae strains. The outermost circle indicates the predicted functional categories of each gene families in the pan-genome. Species-specific gene families are individually blocked with black line (B. bronchiseptica, B. parapertussis, and B. pertussis). Internal circles indicate the presence (solid color) or absence (unfilled) of each gene family in each strain examined. Circles from outer to inner are started with B. bronchiseptica strains followed by B. parapertussis strains and B. pertussis strains. Gene families that are shared in all strains are in the region A, while gene families that are not conserved in all strains are in the region B, C, and D. Region C indicates the phage encoding gene families that are only present in RB50. This figure was created using the Circos software [21].
