Clone of Staphylococcus aureus phage type 187 isolated from people

The aim of this study was to examine whether Staphylococcus aureus of phage type 187 are genetically homogenous with the use of digestion of chromosomal DNA with SmaI and separation of the DNA by pulsed-field gel electrophoresis (PFGE). Sixteen S. aureus phage type 187 were isolated from the hospital patients (12) and the healthy carriers (4) in twelve medical centres in Poland during 1991 and 2005. The PFGE typing proved that the phage type 187 isolates have the same PFGE type (except for one) and constitute one clone.
