A case of epididymitis associated with Panton-Valentine leukocidin Staphylococcus aureus.

A new pattern of disease caused by Panton-Valentine leukocidin (PVL)-positive strains of Staphylococcus aureus is emerging in the UK and worldwide. Community-associated methicillin-resistant S aureus (MRSA) is more likely to produce PVL, a pore-forming cytotoxin inducing leucocyte lysis, which often infects young healthy individuals. The worldwide emergence and continually increasing prevalence of community-acquired PVL-MRSA have recently attracted high-profile media attention and prompted concern regarding the transmissibility and virulence. This paper reports a case of genitourinary tract infection associated with PVL-positive community-associated MRSA in an immunocompetent young man.
