متن کاملPolymorphism in Bordetella pertussis pertactin and pertussis toxin virulence factors in the United States, 1935-1999.
To elucidate the potential role of the etiologic agent in recent increases of pertussis incidence in the United States, we studied the polymorphism in pertactin and pertussis toxin, which are Bordetella pertussis proteins important for pathogenesis and immunity.
