B. pertussis and B. parapertussis are very similar species. Both species cause pertussis (whooping cough) in humans and are separated merely by the toxins they release during infection. B. parapertussis releases toxins that seem to cause a milder form of pertussis (whooping cough). B. bronchiseptica causes respiratory disease in various mammals and occasionally in humans. The species is further separated from B. pertussis and B. parapertussis by being motile.
