Description and significance. Bordetella pertussis is a small, Gram-negative, coccoid bacterium about the size of 0.8 Âµm by 0.4 Âµm. It is an encapsulated immotile aerobe that does not make spores.Bordetella pertussis produces a number of virulence factors, including pertussis toxin, adenylate cyclase toxin, filamentous hemagglutinin, and hemolysin.he current Bordetella pertussis vaccine is a whole-cell vaccine which means that the vaccine uses whole dead B. pertussis cells. The whole-cell vaccine has been very effective for the majority of the population, but some people develop severe adverse reactions to this vaccine.
