Several of the most deadly bacteria in the world alternate between causing symptomatic infections and acting as asymptomatic carriers, where they do not harm their host. One of these is the group A streptococci (GAS). GAS has a control system which switches off or on the virulence factors, that is, the molecules that cause the symptoms and do harm to the patient. The project aims to understand the behaviour of this control system focusing, especially, on the control molecule, Mga as it has a direct effect on several important virulence factors.
