Viral Nervöz Nekrozis Hastalığının Türkiye’deki Durumu

Öz

Etkeni betanodavirus olan Viral nervöz nekrozis (VNN) hastalığı, Türkiye’de ve dünyada birçok balık türünde bildirimi yapılmış viral balık hastalığıdır. Hem deniz hemde tatlı sularda yaşayan sucul canlılarda yüksek mortaliteye neden olmaktadır. Dört genotipi bulunan virusun, Türkiye’de 2023 yılı sonuna kadar RGNNV ve RGNNV/SJNNV genotiplerinin tespit edildiği bildirilmiştir. Ülkemizde ilk defa 2011 yılında levrek (Dicentrarchus labrax) balığında RGNNV genotipi tespit edilmiştir. Sonrasında Akdeniz’de levrek (D. labrax), çipura (Sparus aurata), barbun (Mullus barbatus) ve zarganada (Belone belone) RGNNV virüs bulunmuştur. Karadeniz’ de levrekte (D. labrax) RGNNV ve Ege denizinde levrekte (D. labrax) RGNNV ve çipurada (S. aurata) RGNNV/SJNNV genotipleri bildirilmiştir. Bu çalışmada, Türkiye’de VNN konusunda yapılmış çalışmalar taranmış ve Türkiye’de hastalığın güncel durumunun bir bütün olarak ele alınması amaçlanmıştır.

The Current Status of Viral Nervous Necrosis Disease in Türkiye

Abstract

The agent of Viral Nervous Necrosis (VNN) disease is betanodavirus and is a viral fish disease and VNN disease has been reported in many fish species in Türkiye and around the world. It is known to cause high mortality rates in aquatic animals living in both marine and fresh water. It has been reported that the RGNNV and RGNNV/SJNNV genotypes of the virus, which has four genotypes, were detected in Turkey by the end of 2023. RGNNV genotype was detected in sea bass (Dicentrarchus labrax) for the first time in our country in 2011 and after that has since been found in other fish species such as sea bream (Sparus aurata), red mullet (Mullus barbatus), and garfish (Belone belone) in the Mediterranean region. RGNNV genotypes have also been reported in sea bass (D. labrax) in the Black Sea, and in sea bass (D. labrax) and RGNNV/SJNNV genotypes have been reported sea bream (S. aurata) in the Aegean Sea. In this study, studies on VNN in Turkey were reviewed and it was aimed to discuss the current status of the disease as a whole.
