dc.description.abstract We have constructed an aromatic amino acid auxotrophic mutant of Bordetella bronchiseptica, harbouring mutations in aroA and trpE to investigate the use of such a strain as a live-attenuated vaccine. B. bronchiseptica aroA trpE was unable to grow in minimal medium without aromatic supplementation. Compared to the parental wild-type strain, the mutant displayed significantly reduced abilities to invade and survive within the mouse macrophage-like cell line J774A.1 in vitro and in the murine respiratory tract following experimental intranasal infection. Mice vaccinated with B. bronchiseptica aroA trpE displayed significant dose-dependent increases in B. bronchiseptica-specific antibody responses, and exhibited increases in the number of B. bronchiseptica-reactive spleen cells in lymphoproliferation assays. Immunised animals were protected against lung colonisation after challenge with the wild-type parental strain. With such a broad host range displayed by B. bronchiseptica, the attenuated strain constructed in this study may not only be used for the prevention of B. bronchiseptica-associated disease, but also for the potential delivery of heterologous antigen.
