title: Alcaligin siderophore production by Bordetella bronchiseptica strain RB50 is not repressed by the BvgAS virulence control system.
abstract: A previous study found that alcaligin siderophore production by Bordetella bronchiseptica strain RB50 is Bvg repressed. In contrast, we report that alcaligin production by RB50 does not require Bvg phenotypic phase modulation and that isogenic Bvg(Con) and Bvg(-) phase-locked mutants both produce alcaligin in response to iron starvation.
