'''Comparing the Genomes of ''B. pertussis'', ''B. parapertussis'', and ''B. bronchiseptica'' elucidates differences in host range and pathogenesis.'''

−

*Host interaction factors and virulence determinants were not recently acquired by the more virulent strains (''B. pertussis'' and ''B. parapertussis'').

*Host interaction factors and virulence determinants were not recently acquired by the more virulent strains (''B. pertussis'' and ''B. parapertussis''). This was contrary to expectation.

*Individual traits in the derivative species (''B. pertussis'' and ''B. parapertussis'') that have enabled virulence were generated by independent gene deletions and inactivations by creation of pseudogenes.

*Increased virulence can be explained by:
