This study identifies a prophage-encoded methyltransferase, pamA, that enhances virulence in CA-MRSA by epigenetically upregulating fnbA, promoting biofilm formation and abscess size.

This study identifies the gut as a major reservoir of Staphylococcus aureus that can be transmitted to the skin and worsen atopic dermatitis.

This study shows that gut microbiota depletion allows MRSA to adapt through genetic changes that enhance colonization fitness but reduce antimicrobial resistance and virulence.
