*MRSA, methicillin-resistant Staphylococcus aureus; CC, clonal complex; ST, sequence type; PVL, Panton-Valentine leukocidin; SCC, staphylococcal chromosome cassette; HA/HCA/CR/NR, hospital acquired/healthcare associated/community risk/no risk. One isolate could only be typed by spa and multilocus sequence typing and is not included in the table.
†New ST.
