Strains were genetically typed using PFGE, RAPD analysis, binary typing, mecA/Tn554 probing, or a combination thereof. For AluI eight individual RFLP patterns (a to h; Fig. 2) were identified, whereas the use of RsaI allowed for the identification of seven RFLP patterns (a to g; Fig. 2). Overall, 12 combined patterns were defined.
