Quorum sensing dependent repression of the Staphylococcus aureus transcription termination factor Rho is necessary for pathogenicity

Laura Barrientos, Marion Blum, Florence Couzon, François Vandenesch, Karen Moreau, Pascale Romby, Isabelle Caldelari

The paper shows that quorum sensing-dependent repression of Rho in S. aureus during stationary phase activates exotoxins and affects virulence-related processes.

Panton Valentine leucocidin enhances community-acquired methicillin-resistant Staphylococcus aureus colonization of the gut

Florence COUZON, Nadege BOURGEOIS-NICOLAOS, Yvonne BENITO, Macarena LARROUDE, Anne TRISTAN, Jean-Philippe Rasigade, Binh An DIEP, Florence DOUCET-POPULAIRE, Francois VANDENESCH

This study shows that Panton Valentine leucocidin (PVL) enhances gut colonization of CA-MRSA in mice by improving adhesion to mucus-producing intestinal cells.
