Clonal types were defined on the basis of ClaI-mecA polymorphisms::ClaI-Tn554 patterns::SmaI-PFGE restriction profiles. A total of 185 strains were examined. ClaI-mecA polymorphisms with a prime and ClaI-Tn554 insertion patterns with number codes (e.g., B1) contain small variations from previously described patterns. ClaI-Tn554 insertion patterns with lowercase letters are new patterns not described in previous studies.
