Bordetella parapertussis

A similar, milder disease is caused by 'Bordetella parapertussis'.

Pertussis (bordetella pertussis and bordetella parapertussis).

Bordetella parapertussis is a small Gram-negative bacterium of the genus Bordetella that is adapted to colonise the mammalian respiratory tract.

Bordetella parapertussis shows the most similarity to B. pertussis and was therefore used for research determining the role of PT in causing the typical symptoms of whooping cough.
