The Reemergent 1977 H1N1 Strain and the Gain-of-Function Debate.

abstract：:Staphylococcus aureus is an important human pathogen whose success is largely attributed to its vast arsenal of virulence factors that facilitate its invasion into, and survival within, the human host. The expression of these virulence factors is controlled by the quorum sensing accessory gene regulator (Agr) system. ...
