Available for licensing from the NIH is a vaccine production strain of Bordetella bronchiseptica that produces Bordetella pertussis toxin in high yield. The Bordetella bronchiseptica strain has been modified to eliminate expression of filamentous hemagglutinin, which typically has to be removed in purification of the toxin, thereby reducing the yield of the active vaccine component. Immediately available for licensing is a strain that encodes a mutated pertussis toxin, which does not have to be chemically detoxified.
