A closely related organism, Bordetella pertussis, causes whooping cough in humans. Typically, infection with viruses or Bordetella damages the lining of the upper respiratory tract, which is covered with waving, hair-like structures called cilia. Cilia function by clearing bacteria and debris from the airways. Bordetella toxins further damage the cilia and may lead to secondary bacterial infections that can worsen and prolong symptoms, such as coughing and retching.
