Haemophilus influenzae tipo B Estreptococo beta-hemolitico del grupo A B. Thus systemic manifestations presumably result from dissemination of bacterial components, such as pertussis toxin. FHA, types 2 and 3 fimbriae, pertactin, and pertussis toxin facilitate attachment to the respiratory epithelium. Tracheal cytotoxin is derived from the bacterial cell wall and causes ciliostasis and sloughing of ciliated cells, thus allowing the organism to overcome mucociliary clearance.

Haemophilus influenzae tipo B Estreptococo beta-hemolitico del grupo A B. Thus systemic manifestations presumably result from dissemination of bacterial components, such as pertussis toxin. FHA, types 2 and 3 fimbriae, pertactin, and pertussis toxin facilitate attachment to the respiratory epithelium. Tracheal cytotoxin is derived from the bacterial cell wall and causes ciliostasis and sloughing of ciliated cells, thus allowing the organism to overcome mucociliary clearance.

Adenylate cyclase toxin, a pore-forming cytotoxin that belongs to the RTX family, inhibits phagocyte functions, including chemotaxis, phagocytosis, oxidative burst, and bactericidal activity, and presumably enables the organism to evade local immunity.

Pertussis toxin also impairs phagocyte functions, including neutrophil chemotaxis and phagocytosis. Tracheal cytotoxin, adenilate cyclase toxin, dermonecrotic toxin, and lipo-oligosacharide may contribute to local damage to the respiratory mucosa. La prueba de embarazo es negativa.
