Interim guidance on diagnosis and management of PVL-associated Staphylococcal infections in the UK (Department of Health)
Panton-Valentine leukocidin positive MRSA in 2003: the Dutch situation (a report in the online journal Eurosurveillance)
and, perhaps most relevantly at this time,
Hospital-associated transmission of Panton-Valentine leukocidin (PVL) positive community-associated MRSA in the West Midlands (a report in CDR Weekly, from the Health Protection Agency)
There may, of course, be material in things about MRSA in general: this quick search of INTUTE would be a good place to start.
For research literature on PVL, click here for a search of PubMed (but remember that PubMed does not always link to University of Leicester full text)
