Nasal carriage prevalence of meticillin resistant (MRSA) and meticillin sensitive (MSSA) Staphylococcus aureus for subjects attending a Dublin methadone clinic.

摘要

Miller et al. described patients presenting from the community with clinical and intraoperative findings of necrotizing fasciitis and myositis, caused by community-associated meticillin resistant Staphylococcu aureus (MRSA). Risk factors for these subjects included current or past injection drug users (IDU) (43%), chronic hepatitis C (21%), and HIV positive status (7%). All recovered MRSA isolates were of the same USA 300 genotype strain and carried the Panton-Valentine leukocidin (pvl) toxin genes. USA 300 strain has now been reported from European countries including Denmark and Italy. We report the prevalence of MRSA carriage and its strain type among subjects attending a methadone clinic (over 50% of whom were iv drug users) in Dublin. We also report the prevalence of MSSA (Meticillin sensitive S. aureus) carriage among this population.
