Q

What are the 5 exotoxins important with Bordetella and what do they do?

A

Tracheal cytotoxin- toxic to cells within the trachea

Dermonecrotic toxin- destruction of turbinates in atrophic rhinitis

Adenylyl cyclase toxin- results in fluid loss

Pertussis Toxin- only active in B. pertussis and results in fluid loss

Osteotoxin- lethal to tracheal and bone cells
