title: Induction of tryptophanase in short cells and swarm cells of Proteus vulgaris.
abstract: Tryptophanase was noninducible in swarm cells of Proteus vulgaris despite transport of the inducer tryptophan. Further, cyclic AMP, which stimulated increased levels of tryptophanase in short cells, had no effect on swarm cells.
