*CC, clonal complex; MRSA, methicillin-resistant Staphylococcus aureus; ST, sequence type. Boldface indicates spa types on which multilocus sequence typing analysis was performed.
†The strains spa typed as t003 and t045 had ST225, a single-locus variant of ST5 at the tpi locus. The strain spa typed as t447 had ST5.
‡The strain spa typed as t011 had ST398, and the strain spa typed as t012 had ST36.
§The strain spa typed as t044 had ST728, a single-locus variant of ST80 at the tpi locus. The strain spa typed as t345 had ST772, a single-locus variant of ST1 at the pta locus.
¶The strain spa typed as t223 had ST217, a single-locus variant of ST22 at the tpi locus.
