Magnesium sulfate is known to repress the expression of the virulence factors of Bordetella pertussis that are coordinately regulated by the bvg locus. We have tested the time required by MgSO4 to repress the synthesis of several bvg-regulated mRNA species and found that the promoters of the virulence genes (pertussis toxin, adenylate cyclase, and filamentous hemagglutinin) are repressed in 6 min, while the autogenously regulated promoters of the bvg locus (P1, P3, and P4) are repressed only sev ...[more]
