ABSTRACT

 

Salehi M, Razavilar V, Mirzaei H, Javadi A, Banan Khojasteh SM., Coagulase polymorphism in Staphylococcus aureus from dairy products, Onl J Vet Res., 17 (6): 310-316, 2013. Polymorphism in coagulase gene of Staphylococcus aureus isolated from raw milk, butter, ice cream and cheese is reported. The gene from 116 S. aureus isolates produced 4 PCR products of 600bp to 850bp. RFLP with AluI restriction enzyme  grouped the isolates into 5 genotypes and 2 of S. aureus accounted for 63.7% of isolates.

 

Key words: Molecular typing, Staphylococcus aureus, dairy products, polymorphism, coagulase gene.
