A serological survey on ınfectious pancreatic necrosis virus (IPNV), viral hemorrhagic septicemia virus (VHSV) and ınfectious hematopoietic necrosis virus (IHVN) from rainbow trout in Turkey

Öz

Infectious pancreatic necrosis (IPN), viral hemorrhagic septicemia (VHS) and infectious hematopoietic necrosis (IHN) are the most significant viral diseases of salmonid species. This study examined the seroprevalence of infectious pancreatic necrosis virus (IPNV), viral hemorrhagic septicemia virus (VHSV) and infectious hematopoietic necrosis virus  (IHNV) in rainbow trout cultured in Turkey. A total of 597 serum samples of adult trout were obtained from 18 commercial trout farms in the Middle and Eastern Black Sea regions of Turkey and were then examined by the virus neutralization test. As a result of the test, VHSV and IHNV antibodies were not detected. However, IPNV antibodies were found in 11 of 18 trout farms (61.1%) and 45 of 597 serum samples (7.5%). Three viral agents characterized as causing persistent infections were serologically screened for the first time in Turkey. The high seropositivity rate against IPNV was namely caused by asympomatic carrier broodstock fish.

Türkiye’deki Gökkuşağı Alabalıklarında Enfeksiyöz Pankreas Nekrozu Virüsü (IPNV), Viral Hemorajik Septisemi Virüsü (VHSV) ve Enfeksiyöz Hematopoetik Nekroz Virüsü’nün (IHNV) Serolojik Olarak Araştırılması

Öz

Enfeksiyöz pankreas nekrozu (IPN), viral hemorajik septisemi (VHS) ve enfeksiyöz hematopoetik nekroz (IHN), salmonid türlerinin en önemli viral hastalıklarıdır. Bu çalışmada, Türkiye’de yetiştirilen gökkuşağı alabalıklarında enfeksiyöz pankreas nekrozu virüsü (IPNV), viral hemorajik septisemi virüsü (VHSV) ve enfeksiyöz hematopoetik nekroz virüsü (IHNV) seroprevalansı incelenmiştir. Türkiye’nin Orta ve Doğu Karadeniz bölgelerinde bulunan 18 ticari alabalık çiftliğinden toplam 597 adet alabalığı kan serumu örneği alınmış ve daha sonra virüs nötralizasyon testi ile incelenmiştir. Test sonucunda VHSV ve IHNV antikorları tespit edilmedi. Ancak, IPNV antikorları 18 alabalık çiftliğinin 11’inde (%61,1) ve 597 serum numunesinin 45’inde (%7,5) bulundu. Türkiye’de kalıcı enfeksiyonlara neden olan üç viral ajan serolojik olarak tarandı. IPNV’ye karşı yüksek seropozitiflik oranı, yani asempomatik taşıyıcı yavru balıklarından kaynaklanmıştır.
