Abstract
Hamster tracheal organ culture was employed as a model for the study of the pathogenesis of infection due to Bordetella pertussis. Scanning electron microscopy provided a three-dimensional view of the surface infection of the tracheal explants. Phase I B. pertussis attached only to the ciliated epithelial cells, and a sequence of events involving the injury, expulsion, and destruction of these differentiated cells occurred. This in vitro model provides insights into the mechanisms by which B. pertussis mediates host cell injury at the site of infection.
