Production of recombinant Bordetella pertussis serotype 2 fimbriae in Bordetella parapertussis and Bordetella bronchiseptica: utility of Escherichia coli gene expression signals.
Serotype-specific fimbriae of Bordetella pertussis are considered potential components of new-generation vaccines against whooping cough. Attempts to characterize fimbriae, and indeed other virulence determinants, produced by B. pertussis have been frustrated on one hand by low yields from B. pertussis itself and on the other by an inability to produce native recombinant products in Escherichia...
متن کاملPolymorphism of repeated regions of pertactin in Bordetella pertussis, Bordetella parapertussis, and Bordetella bronchiseptica.
Pertactin is an outer membrane protein expressed by Bordetella pertussis, Bordetella parapertussis, and Bordetella bronchiseptica that induces protective immunity to Bordetella infections. The immunodominant and immunoprotective epitopes of pertactin include two repeated regions, I and II. Comparison of these two repeated regions showed that B. parapertussis pertactin is invariant, whereas B. p...
متن کاملNucleotide sequence homology to pertussis toxin gene in Bordetella bronchiseptica and Bordetella parapertussis.
Multiple strains of Bordetella parapertussis and B. bronchiseptica were examined for the presence of nucleotide sequences which hybridized with a cloned 4.5-kilobase (kb) fragment of B. pertussis DNA containing the genes responsible for pertussis toxin expression. All six B. parapertussis strains tested had nucleic acid sequences that hybridized with the cloned 4.5-kb fragment in Southern blot ...
متن کاملInfection with Bordetella parapertussis but not Bordetella pertussis causes pertussis-like disease in older pigs.
The 3 major Bordetella species--namely, B. pertussis, B. parapertussis, and B. bronchiseptica--can be distinguished by their different host ranges. B. bronchiseptica infects a wide range of mammals (including humans), whereas B. pertussis infects only humans and, under experimental conditions, mice and pigs. In contrast, B. parapertussis, also a causative agent of pertussis, displays a unique h...
متن کاملReciprocal protective immunity against Bordetella pertussis and Bordetella parapertussis in a murine model of respiratory infection.
The protective immunity induced by infection with Bordetella pertussis and with Bordetella parapertussis was examined in a murine model of respiratory infection. Convalescent mice that had been infected by aerosol with B. pertussis or with B. parapertussis exhibited a protective immune response against B. pertussis and also against B. parapertussis. Anti-filamentous hemagglutinin (anti-FHA) ser...
