Abstract
The identification of fragments of pathogenicity islands (SAPI1, vSaα and vSaβ) in 11 clinical strains of Methicillin-resistant Staphylococcus aureus (MRSA), referred on the basis of spa- sequence typing and the restriction-modification test to different genotypes, has been performed. A set of studied pathogenicity islands was shown to be strain-specific and be available for usage as an epidemiological marker of hospital strains of Staphylococcus aureus.
