Objective. To reveal molecular types of nosocomial and community-acquired strains of S. aureus in different regions of Russia.
Materials and Methods. 575 (187 MRSA and 388 MSSA) strains, isolated from pediatric patients during multicenter studies (1997–2008) from 36 medical institutions in 24 Russian cities were included in the study. For molecular typing 186 strains with unique resistance profile within each ward of each medical institution were selected. The following typing methods were used: MLVA, spa, SCCmec and MLST.
