The evolution of Bordetella pertussis from a to Bordetella bronchiseptica has occurred through largeinactivation and rearrangements, largely driven by the spread of insertion sequence element repeats throughout the genome. B. pertussis is widely considered to be monomorphic, and recent evolution of the B. pertussis genome appears to, at least in part, be driven by vaccine-based selection. Given the recent global resurgence of whooping cough despite the wide-spread use of vaccination, a more thorough understanding of B. pertussis genomics could be highly informative. In this chapter we discuss the evolution of B. pertussis, including how vaccination is changing the circulating B. pertussis population at the genelevel, and how new sequencing technologies are revealing previously unknown levels of intercommon ancestor similar scale gene loss, and intra-strain variation at the genome-level.
