Abstract

VHS can be diagnosed by the isolation of virus from infected fish in an appropriate cell line then identified by different serologicaltechniques such as ELISA, virus neutralization, immunofluorescence, immunoperoxidase and complement fixation tests. ELISA is over to the other serologicaltests by the repeatability, simplicity, rapidity and cheapness.In this research only one antibody which raised in rabbit was used for the detection of VHSV antigen. Furthermore, this antibody was labeled withbiotin and used as test conjugate. Estimated protein concentration of produced antibody (anti-VHSV F1 ɣ-globulin fraction) was 28 mg/ml. The microwells werecoated with 10 μg/ml anti-VHSV ɣ-globulin fraction. Then the suspected samples were reacted. If the samples were containing virus, biotinylated anti VHSV ɣglobulinfraction binds to the antigen and biotinylated ɣ-globulin fraction react with HRP labeled avidin. The colour is developed and read by a reader fallowingaddition of TMB substrate. In the research, developed ELISA was detecting all known VHSV Subtypes (strain F1, HE, 23.75). Also this developed ELISA washighly specifique to VHSV and was not giving the cross reaction with other fish viruses such as IHNV, PFR, PR and all known IPN serotypes. As a result,sensitivity of that ELISA method is 104.75/0,1 ml DKID50 and method can detect 80 ng virus protein.

Özet

VHS, enfekte balık dokusundaki virüsün, duyarlı doku kültürlerinde izolasyonundan sonra ELISA, virüs nötralizasyon, immunofloresans, immunoperoksidazve komplement fiksasyon gibi serolojik testlerle teşhis edilmektedir. ELISA, tekrarlanabilir olması, kullanımının basit olması, çabuk yapılabilmesi veucuz olmasıyla diğer serolojik testlere göre daha çok tercih edilmektedir.Bu çalışmada VHS antijenini tespit edebilecek tavşandan elde edilen sadece bir antikor kullanıldı. Bu antikor biotin ile işaretlenerek testte konjugatolarak kullanıldı. Üretilen antikorun (anti-VHSV F1 ɣ-globulin fraksiyonu) protein konsantrasyonu 28 mg/ml olarak ölçüldü. Mikroplak kuyucukları 10mikrogram/mililitre (μg/ml) anti-VHSV ɣ-globulin fraksiyonu ile kaplandı. Daha sonra şüpheli örnek ilave edildi. Örnekteki VHSV biotinlenmiş anti-VHSV ɣglobulinfraksiyonuna bağlandı. Bu aşamadan sonra ilave edilen horse radish peroksidase (HRP) enzimi ile işaretli avidin, konjugattaki biotin ile bağlandı. Sonolarak tetramethylbenzidine substrat (TMB) eklenmesiyle renk şekillendi ve ELISA okuyucuda 450 nonometrede (nm) okutturuldu. Bu çalışmada geliştirilen ELISAyöntemi ile bilinen tüm VHSV alttipleri (07.71, HE, 23.75) tespit edilebilmektedir. Yine bu yöntem VHSV’ye oldukça spesifiktir ve İnfeksiyöz HematopoetikNekrozis Virüsu (IHNV), Pike Fry rhabdovirus (PFR), Perch rhabdovirus (PR) ve bilinen tüm İnfeksiyöz Pankreatik Nekrozis Virüsu (IPNV) serotipleriyle çaprazreaksiyon vermemektedir. Sonuç olarak geliştirilen bu ELISA yöntemi 80 nanogram (ng) virüs proteinini ve DKID50 değeri 104,75/0,1 ml olan virüsü tespitedebilmektedir.
