*MRSA, methicillin-resistant Staphylococcus aureus; ST, sequence type; NT, nontypeable. Based on spa and staphylococcus cassette chromosome (SCC) mec typing.
†These strains were classified into clonal complex (CC) 5 and had a nontypeable SCCmec type III element.
‡This strain had a nontypeable SCCmec element belonging to CC30.
§These strains harbored SCCmec type IV and could not be classified into a CC.
¶spa types with <5 spa repeats.
