Molecular typing ofStaphylococcus aureusbased on PCR-RFLP ofcoagene and RAPD analysisThe aim of this study was molecular identification ofS. aureusstrains isolated from mastitic milk samples and establishing the genetic relationship between strains isolated from cows belonging to the same herd. In all 43 isolated strains thegapgene (930 bp) was amplified, which enabled their affiliation to theStaphylococcusgenus to be established. PCR-RFLP withAluI endonuclease of thegapgene as well asnuc(450 bp) andcoa(1130 bp) gene amplification allowed preciseS. aureusspecies identification. One hundred percent of the genetic relationship between strains was establishedviaRAPD-PCR and coa-typing.
