SigB Is a Dominant Regulator of Virulence in Staphylococcus aureus Small-Colony Variants

Staphylococcus aureus small-colony variants (SCVs) are persistent pathogenic bacteria characterized by slow growth and, for many of these strains, an increased ability to form biofilms and to persist within host cells. The virulence-associated gene expression profile of SCVs clearly differs from tha...
