Coagulase gene polymorphism of staphylococcus aurreus isolated from subclinical bovine mastitis

Özet: Bu çalışma, üç farklı şehirden (Hatay, Gaziantep ve Burdur) toplanan mastitisli sığır sütlerinden izole edilen 80 Staphylococcus aureus susunun koagulaz gen polimorfizmini araştırmak amacıyla yapıldı. Seksen S. aureus susu 5 farklı polymerase chain reaction (PCR) amplikonu oluştururken, 79 izolat 1 amplikon ve 1 izolat 2 amplikon oluşturdu. İzolatlar, koagulaz geninin restriction fragment length polymorphism (RFLP) analizi ile 9 genotipe ayrıldı. İki yaygın genotip izolatların % 73,8'ini oluşturdu. Sonuçlar, çalışılan bölgelerde farklı genotiplerin olduğunu ve bunlardan sadece bir veya iki genotipin dominant olduğunu göstermektedir

Subklinik inek mastitis'lerinden izole edilen staphylococcus aureus suşlarinin koagulaz gen polimorfizmi

Abstract: This study was conducted to investigate the coagulase gene polymorphism of Staphylococcus aureus isolated from subclinical bovine mastitic milk samples from 3 different Turkish cities (Hatay, Gaziantep, and Burdur). Amplification of the coagulase gene from 80 5. aureus isolates produced 5 different polymerase chain reaction (PCR) products; 79 isolates showed only 1 amplicon, and 1 isolate showed 2 amplicons. The isolates were grouped into 9 genotypes by analysing the restriction fragment length polymorphism (RFLP) of the gene; the 2 most common genotypes accounted for 73.8% of the isolates. The results indicated that many coagulase gene genotypes are present in the studied regions and only 1 or 2 genotypes predominated.
