Methicillin-resistant Staphylococcus aureus (MRSA) clones are rapidly increasing beyond the hospital into the community, livestock farming and environmental settings. An Italian man, a professional diver working in Egypt, was admitted to Infectious Diseases Clinic-ASST Fatebenefratelli Sacco for ulcerative skin lesions. An MRSA strain was isolated from the lesions' purulent exudate and the nasal colonization was also ascertained. The strain, characterized by whole genome sequencing, resulted to be Panton-Valentine Leukocidin (PVL) positive, SCCmecI - spa-type t504, and belonging to the sequence type 1153, sporadically described worldwide.
