In ''Francisella'' virulence, a set of regulators are essensial for its activation. These regulators include the heterodimer of SspA, macrophage growth locus A (MglA) and pathogenicity island gene regulator (PigR). The guanosine-tetraphosphate (ppGpp) is also involved in coordinating the virulence. | In ''Francisella'' virulence, a set of regulators are essensial for its activation.
