All species of the genus bordetella contain genes for pertussis toxin of bordetella pertussis

Abstract

A molecular probe for the PT-operon of B. pertussis hybridized with 4.7 Kb EcoRI-fragments of chromosomal DNAs of B. pertussis strain 475 phase I, phase IV, B. parapertussis strains 504 and 17903, B. bronchiseptica strain 214, B. parapertussis strain 17903-convertant of B. pertussis phage 134 but not with phage 134 DNA under stringent conditions of DNA-DNA hybridization. This fact indicates the presence of PT-genes in all Bordetella species. Since there is no production of PT in B. parapertussis and B. bronchiseptica, a presence of regulatory mutations in the PT-operon or absence of the functionally active vir-gene product in these species is suggested.
