^aIsolation sources: i, site of infection; e, environment; c, carriers. 

^bResults of PFGE typing of S. aureus isolates have already been included in the multicenter analysis of MRSA clones present in Poland (19). 

^cExplanation of resistance patterns: K, kanamycin resistance; P, penicillin resistance; R, rifampin resistance; S, streptomycin resistance; T, tetracycline resistance.
