Abstract: White spot syndrome virus (WSSV) is one of the major causes of disease in the shrimp culture industry causing enormous economic losses. In this study, we displayed peptides from a cDNA library obtained from the hemolymph of shrimp infected with WSSV, on the surface of phage and screened for the peptides that interacted with the WSSV. One WSSV binding protein (WBP) gene was found to consist of 171bp that had no matches in the NCBI database. This WBP was shown to bind to the VP26 protein of the WSSV by Western blotting. In addition, WBP reduced the binding of WSSV to shrimp haemocytes from 2.0×107 copies in the control to 6.0×102 after treatment with 80μg of WBP. The survival rate of shrimp after WSSV were mixed with WBP at 80μg, was 89% and the binding of WBP remained unchanged for at least 24h. Therefore, the results indicate that the WBP can bind to VP26 and inhibit the invasion of WSSV into host cells. This finding may introduce another future way to try to fight this disease in shrimp culture. [ABSTRACT FROM AUTHOR]
