Afyonkarahisar İli ve Çevresinde Maedi- Visna Virus Enfeksiyonunun Klinik ve Serolojik Olarak Araştırılması

Öz

Bu çalışmanın amacı Maedi-Visna Virus (MVV) enfeksiyonunun hem normal hem de MVV ile ilişkili bozuklukların görüldüğü koyun sürülerinde araştırılmasıdır. Afyonkarahisar ilinde kuru öksürük, zayıflama, burun akıntısı gibi kronik solunum sistemi semptomlarının görüldüğü koyun sürüleri ile klinik olarak sağlıklı toplam 10 koyun sürüsünden kan örnekleri alındı. Bu sürülerden ikisinde daha önce solunum sistemi enfeksiyonuna yönelik ilaç tedavisi de yapılmasına rağmen önemli bir düzelme gözlenmediği bildirildi. İndirekt ELISA sonuçlarına göre klinik semptomların görüldüğü dört işletmenin üçünde %9 ile 14.8 arasında değişen değerlerde seropozitiflik saptandı. Sağlıklı görünüme sahip 6 sürünün ikisinde de %9.3 (3/32) ve %3.1 (1/17) oranları belirlendi. Sonuç olarak 10 işletmenin 5’inde %3.1 ile 14.8 aralığında ve toplam 294 örneğin 17’sinde (%5.7) MVV pozitiflik tespit edildi. Düşük enfeksiyon oranları ve enfeksiyon geçmişinin nisbeten yeni oluşu gibi olası nedenlerle, enfeksiyon ile klinik bozukluk varlığına göre sürü bazında istatistiksel olarak önemli bir ilişki bulunmadığı belirlendi.

A clinical and serological investigation for Maedi-Visna Virus (MVV) infection in Afyonkarahisar province

Abstract

Aim of this study, to investiagate the Maedi-Visna Virus (MVV) infection in both normal and MVV related disorders observed sheep flocks. Blood samples was collected from clinically healthy and chronical respiratory system problems like dry cough, wasting, nasal discharges syptoms have been seen 10 sheep flocks in Afyonkarahisar province. Out of these flocks, medical treatment has been applied previously for respiratory system infection in 2 flocks, however significant recovery was not seen observed. As a result of indirect-ELISA, seropositivity was detected between 9% and 14.8% in 3 of 4 flocks that have clinical disorders. The infection was detected in 2 of 6 clinically normal flocks with 9.3% (3/32) and 3.1% (1/17). As a result, out of 10 enterprises, MVV positivity was detected in 5 between 3.1% and 14.8% proportions, and total of 294 samples, 17 (5.7%) was found to be positive. Statistically, significant correlation was not detected between infection and clinical disorder presence in the flock basis, probably due to low infection rates and relatively new infection history.
