Sığır löykozis virus (Enzootik sığır löykozu) enfeksiyonunun kontrolü, eradikasyonu ve ekonomik açıdan önemi

Bovine Löykozis (BL) enfeksiyonuna neden olan Bovine Löykozis Virus (BLV) tüm dünyada yaygın olarak seyretmektedir. BL enfeksiyonu sığırlarda doğal olarak şekillenen, lenfoid kanser, malign lenfoma, persiste lenfositozis ve lenfoid hücrelerin beningn proliferasyonu ile karakterize bir hastalıktır. Enfeksiyon, lenfosarkoma ve lenfositozis formlarının belirli coğrafik bölgelerde ortaya çıkması nedeniyle "Enzootik Bovine Löykozis" olarak isimlendirilmiştir. Dünya'da ve Türkiye'de hayvancılık sektöründe yaşanan çeşitli problemler hayvan sağlığını, yetiştiriciliğini, populasyonu, elde edilecek hayvansal ürünlerin kalitesini, miktarını ve tüketimini önemli düzeyde etkilemektedir. Avrupa Birliği ülkelerinde hayvan ithali sırasında gümrük girişlerinde damızlık sığırlar BL enfeksiyonu yönünden taranmaktadır. Ancak Türkiye'de hastalığın varlığı ortaya konmuş olmasına rağmen henüz yetküi kurumlarca belirlenmiş herhangi bir kontrol ve eradikasyon projesi yoktur. Bu derlemede, ekonomik açıdan önem arz eden BLV enfeksiyonunun sürülerdeki kontrolünü sağlamak ve eradikasyonunu gerçekleştirmek amacıyla ne tür uygulamaların yapıldığı açıklanmıştır.

Control, eradication and economic importance of infection of bovine leucosis virus (Enzootic bovine leucosis)

Bovine Leucosis (BL) infection that caused by Bovine Leucosis Virus (BLV) is spreading in worldwide. BL infection is a disease that shaped in catties naturally by lymphoid cancer, malign lymphoma, persistent lymphocytosis and beningn proliferation and lymphoid cells. Infection was called name as "Enzootic Bovine Leucosis" because of its appearance lymphosarcoma and lymphocytosis forms in definite geographical areas. The problems that living in the sector of animal in the world and Turkey effects the animal health, breeding, population, the qualities of the animal products which will be obtained and its amount and consumption. BL infection stallion catties are screened while their exports in customs in European countries. But although that disease had been detected in Turkey, no have determined a control and eradication programmes from authorized institution. In this review, it is explained that which methods are being done for the purpose of making eradication and to provide the control of BLV infection on herd which is important for economy.
