Pertussis is a highly contagious acute respiratory disease caused by the bacteria Bordetella pertussis. This disease has 3 stages: catarrhal, paroxysmal, and convalescent.
M icrobiology. Bordetella pertussis, a small gram-negative coccobacillus, is the most important cause of pertussis. B. parapertussis causes similar, but often milder type of cough with posttussive vomiting. B. bronchiseptica and B. avium are important pathogens in wild and domestic animals.ne explanation for the increase might be the adaptation of B. pertussis bacteria to vaccine-induced immunity, because the antigenic divergence has been recently found between the B. pertussis vaccine strains and circulating strains (13, 60, 61).
