What disease can bordetella pertussis cause?

Whooping cough: Whooping cough, formally called pertussis, is a respiratory disease that in its classic form in small children can produce paroxysms of cough strong enough to fracture a rib and long enough to cause lack of oxygen in the body. It is especially harmful in infants less than 12 months old who are not yet immunized. Because of waning immunity from vaccine, boosters are now recommended in adults.

Whooping Cough: Whooping cough usually is caused by pertussis. But this also can cause pneumonia. Even rare infections of the brain.
