The objective was to investigate the genotypic characteristics and distribution of Staphylococcus aureus in 9 dairy herds of Tabriz and Urmia regions which are located in east and west Azerbaijan provinces, respectively, Iran. In this study 58 S. aureus isolates were recovered from 370 milk samples of cows with clinical and subclinical mastitis. S. aureus isolates were identified on the basis of the cultural and biochemical properties as well as by amplification of the aroA gene specific to S. aureus and then were analyzed using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) of the coagulase gene (coa). Amplification of the variable region of the coa gene..
