Summary: The bordetellae
The genus Bordetella contains nine species, three of
which have been studied in detail: B. pertussis, B. para-
pertussis and B. bronchiseptica. These three species
have different host ranges and cause different diseases in
their hosts. B. pertussis causes whooping cough predom-
inantly in children aged 110 years and is recognised as
a cause of persistent cough in adults.15
B. parapertussis
also causes whooping cough in children, but disease due
to B. parapertussis has often been regarded as milder
than that caused by B. pertussis.6
B. parapertussis has
evolved as two distinct lineages, one adapted to the
human host and the other adapted to ovine hosts.710
In
contrast to the severe restriction in host range exhibited
by B. pertussis and B. parapertussis, B. bronchiseptica
infects a wide variety of mammals, although infections
in humans are rare. Although described as a pathogen, B.
