Abstract

Infectious Pancreatic Necrosis (IPN) is an acute, contagious, systemic disease of salmonid species that is caused by birnavirus. The disease is transmitted both horizontally and vertically within and between species. Laboratory diagnosis of IPN is based on the isolation of virus in susceptible cell cultures and identification of the agent by serum neutralisation test (NT), Enzyme-Linked Immunosorbent Assay (ELISA) and indirect immunofluorescent antibody techniques (IFAT). Infectious Pancreatic Necrosis Virus (IPNV) has an suppressive effect on the causative agents of Viral Hemorrhagic Septicemia (VHS), Infectious Hematopoietic Necrosis (IHN) and Spring Viremia of Carp (SVC) diseases. Because of this; it is possible to obtain false negative results for other fish viruses. Therefore, it is necessary to make neutralisation with IPNV antisera for the isolation and identification of other fish viruses. The produced antisera are going to be used for the diagnosis of IPN disease by neutralisation test and to eliminate the suppresive effect of IPNV on causative agents of other viral fish diseases. In this project, neutralising antisera against three different serotypes of IPNV (Sp, Ab and VR299) were produced by the injections of rabbits using different immunisation programmes and different adjuvants. The proper method was determined according to the titre of neutralizing antisera and results of cross reactions with different strains of IPNV, field isolates of IPNV and other fish viruses (VHSV, IHNV and SVCV).

Özet

İnfeksiyöz pankreatik nekrozis (IPN) özellikle salmonidlerin kontagiyöz, horizontal ve vertikal olarak bulaşan, persiste özelliğe sahip birnavirusların neden olduğu viral bir enfeksiyonudur. Hastalığın tanısında duyarlı hücre kültüründe virus izolasyonunu takiben, nötralizasyon test (NT), indirekfluoresan antikor test (IFAT) ve Enzyme-Linked Immunosorbent Assay (ELISA) gibi tekniklerle identifikasyonu yapılmaktadır. Viral hemorajik septisemi (VHS) ve infeksiyöz hemapoetik nekrozis (IHN) ve Spring Viremia of Carp (SVC) gibi diğer viral balık hastalıklarının tanısında olası İnfeksiyöz Pankreatik Nekrozis Virus (IPNV)’unun diğer virusları baskılayıcı özelliğinin ortadan kaldırılması için örneklerin mutlaka IPNV antiserumu ile nötralize edilerek de ekilmesi gerekmektedir. Bu çalışmada IPN hastalığının tanısında nötralizasyon testte ve ayrıca viral balık hastalıklarının tanısında yanlış negatif sonuçlar alınmasını engellemek amacı ile IPNV baskılayıcı etkisinin ortadan kaldırılması için kullanılmak üzere IPNV’unun üç farklı serotipine (Sp, Ab ve VR299) karşı antiserum üretilmiştir. Antiserum üretiminde farklı yöntemler ve adjuvantlar kullanılarak Sp, Ab ve VR299 serotiplerinin herbirine karşı yüksek titrede; diğer serotipler, sahadan izole edilen viruslar ve Viral hemorajik septisemi virusu (VHSV), infeksiyöz hemapoetik nekrozis virusu (IHNV) ve Spring Viremia of Carp virusu (SVCV) ile çapraz reaksiyon vermeyen veya en az veren yöntem belirlenmiştir.
