Prophage acquisition by Staphylococcus aureus contributes to the expansion of Staphylococcal immune evasion

R. Nepal, G. Houtak, G. Bouras, M. Ramezanpour, S. Feizi, G. Shaghayegh, K. Shearwin, A. J. Psaltis, P.-J. Wormald, S. Vreugde

This study shows that acquisition of the {phi}Sa3int prophage by S. aureus alters its exoproteome, enhancing immune evasion and chronic infection potential.
