  bordetella is a genus of small (0.2 - 0.7&nbsp;Âµm), gram-negative coccobacilli of the phylum proteobacteria. bordetella species, with the exception of b. petrii, are obligate aerobes, as well as highly fastidious, or difficult to culture. three species are human pathogens (b. pertussis, b. parapertussis, b. bronchiseptica); one of these (b. bronchiseptica) is also motile. b. pertussis and occasionally b. parapertussis cause pertussis or whooping cough in humans, and some b. parapertussis strains can colonise sheep. b. bronchiseptica rarely infects healthy humans, though disease in immunocompromised patients has been reported. b. bronchiseptica causes several diseases in other mammals, including kennel cough and atrophic rhinitis in dogs and pigs, respectively. other members of the genus cause similar diseases in other mammals, and in birds (b. hinzii, b. avium). the bordetella genus is named after jules bordet. ==pathogenesis== the most thoroughly studied of the bordetella species are b. bronchiseptica, b. pertussis and b. parapertussis, and the pathogenesis of respiratory disease caused by these bacteria has been reviewed.{{cite book | author = cotter pa, miller jf | title = bordetella in: principles of bacterial pathogenesis (groisman ea, ed.) | p
