Serologic prevalence of Ornithobacterium rhinotracheale infection in commercial layers

. Amaç: Bu çalışmada ticari yumurtacı tavuk işletmelerinde bulunan tavuklarda Ornithobacterium (O.) rhinotracheale enfeksiyonunun serolojik prevalansının belirlenmesi amaçlandı.Gereç ve Yöntem: Konya, Aksaray, Karaman, Ankara ve Gaziantep illerinde bulunan 26 farklı kümesteki yumurtacı tavuklardan 650 kan serum örneği toplandı. Örnekleme yapılan tavukların hiç birisi daha önceden O. rhinotracheale enfeksiyonuna karşı aşılanmamışlardı. O. rhinotracheale'ye karşı oluşmuş antikorların varlığı ELISA testi ile belirlendi.Bulgular: Toplam 650 kan serum örneğinden 113 (%17.4)'ünde O. rhinotracheale antikoru tespit edildi. Bu 113 pozitif serum örneği örnekleme yapılan 26 kümesin 12 (%46.2)'sinden toplanmıştı. Enfekte 12 kümes, Konya, Gaziantep, Ankara ve Karaman illerindeki 12 farklı çiftliğe aitti. Öneriler: Bu çalışmanın sonuçları göstermiştir ki, Türkiye'deki ticari yumurtacı tavuk kümeslerinde O. rhinotracheale enfeksiyonu yüksek bir prevalansa sahiptir.

Ticari yumurtacı tavuklarda Ornithobacterium rhinotracheale enfeksiyonunun serolojik prevalansı

Aras Z, Sayin Z, Sanioglu G. Serologic prevalence of Ornithobacterium rhinotracheale infection in commercial layers.Aim: The purpose of this study was to determine the serological prevalence of Ornithobacterium (O.) rhinotracheale infections in commercial layers. Materials and Methods: A total of 650 blood serum samples were collected from 26 different layer flocks located in Konya, Aksaray, Karaman, Ankara, and Gaziantep provinces. None of the chickens have been vaccinated against O. rhinotracheale prior to sampling. The presence of antibodies against O. rhinotracheale in each sample was determined by ELISA. Results: Of the 650 serum samples, 113 (17.4%) were found to be positive for O. rhinotracheale antibodies. These 113 positive sera were collected from 12 (46.2%) out of 26 flocks. The twelve infected flocks belonged to 12 different farms form Konya, Gaziantep, Ankara and Karaman. Conclusion: The results of this study indicated that O. rhinotracheale infection is at high prevalence in the commercial layer flocks from this part of Turkey
