Application of bioinformatics in diagnosis of White Spot Syndrome Virus
White spot syndrome is one of the major problems in shrimp culture worldwide. There are different techniques like Dot blotting, PCR and using monoclonal antibodies for diagnosis of White Spot Syndrome Virus (WSSV). In the latter method, by using laboratory animals, monoclonal antibodies against different antigenic domains of proteins of the virus are developed. Then the reactivity of these antibodies with all proteins of shrimp can be tested by ELISA. As it is not known at the start of the test which parts of a protein are strong epitopes and so there is a need to test many peptides, this method is expensive and time consuming. One of the solutions for this problem is prediction of epitopes, synthesis of few peptides, and testing these peptides. Since VP28 is the most important protein of WSSV capsid, the sequences of amino acids of VP28 of four isolates of WSSV from different parts of the world were collected for this study. By using bioinformatics method, after aligning of sequences the consensus sequence was identified. For prediction of antigenic domains of V 28, seven different programs were used. The analysis through the computer programme resulted in prediction of five epitopes in V 28. These parts of the protein can now be synthesized and tested for identification of the virus.
