Hyperproduction of Alpha-Hemolysin in a sigB Mutant Is Associated with Elevated SarA Expression in Staphylococcus aureus

To evaluate the role of SigB in modulating the expression of virulence determinants in Staphylococcus aureus, we constructed a sigB mutant of RN6390, a prototypic S. aureus strain. The mutation in the sigB gene was confirmed by the absence of the SigB protein in the mutant on an immunoblot as well a...
