Özet
Amaç: Mastitisli ineklerin süt örneklerinden izole edilen ve fenotipik olarak metisilin dirençli Staphylococcus aureus (MRSA) olduğu belirlenen izolatlarda, mecC gen varlığının araştırılması amaçlandı.Gereç ve Yöntem: Çalışma materyalini mastitisli ineklerden izole edilen 150 adet Staphylococcus aureus (S. aureus) suşu oluşturdu. İzolatlardaki metisilin direnci sefoksitin disk di-füzyon testi ve ticari PBP2a lateks aglütinasyon testi ile belir-lendi. MRSA izolatlarında mecA ve mecC gen varlığı Polime-raz Zincir Reaksiyonu (PZR) ile analiz edildi.Bulgular: Yüz elli adet S. aureus izolatından 28'inin (%18.6) sefoksitin disk difüzyon testi ile fenotipik olarak metisilin dirençli olduğu belirlendi. MRSA izolatlarının 21'inde (%75) lateks test ile aglütinasyon ve PZR ile mecA geni belirlendi. Yedi (%25) izolatta aglütinasyon ve mecA geni belirlenemez-ken, mecC geni taşıdığı tespit edildi. Öneri: Türkiye'de mastitisli ineklerde mecC MRSA izolasyon oranının beklenmedik şekilde yüksek olduğu ve fenotipik olarak MRSA olarak identifiye edilen izolatların genotipik doğrulanmasında mecC geni yönünden de analiz edilmesi gerektiği kanaatine varıldı.
Aim: It was aimed to investigate the mecC gene in phenoty-pically methicillin-resistant Staphylococcus aureus (MRSA), isolated from mastitic milk samples.Materials and Methods: This study was performed on 150 S. aureus strains isolated from mastitic cattle. Resistance to methicillin was determined by cefoxitin disc diffusion met-hod and commercial PBP2a latex agglutination test. Detecti-on of mecA and mecC gene in MRSA isolates were carried out by Polymerase Chain Reaction (PCR).Results: Twenty eight (18.6%) out of 150 S. aureus isolates were identified phenotypically as MRSA by cefoxitin disc diffusion test. Aglutination and mecA gen were detected in 21 (75%) MRSA isolates by latex agglutination test and PCR, mecC gene was determined in 7 (25%) MRSA isolates in all of which no positivity by latex agglutination test and mecA-PCR analysis was observed.Conclusion: mecC MRSA isolation rate was determined as to surprisingly be high in mastitic cattle in Turkey, and mecC gene should also be further analyzed for genotypic confirma-tion of MRSA isolates that already identified by phenotypic methods.
