n = number of isolates.
PVL = Panton-Valentine leukocidin.
CMRSA = Canadian epidemic meticillin-resistant Staphylococcus aureus.
^a spa types classified according to eGenomics (http://tools.egenomics.com).

^c Five isolates recovered from five unexposed rooms; one isolate recovered from one MRSA exposed room.
^d One isolate recovered from one unexposed room.
^e For three MRSA exposed rooms, the patient’s MRSA isolate was not collected.
^f Five MRSA isolates are from MRSA exposed rooms that were sampled.
