Homology Comparison of White Spot Syndrome Baculovirus(WSSV) from Penaeid shrimp
Abstract: Homology of three WSSV isolates.which were sampled from representative maritime space of China:Tanghai isolate(13o Bay of China),Ningbo isolate(East China Sea).Shenzhen isolate (South China Sea)was compared.Both of the genome RFLP patterns and the characteristic structural proteins SDS-PAGE electropherograms showed that they were quite$a/’ae.It suggested that they were the same kind of WSSV virus that caused explosive epidemic diseases of shrimps(EEDs)throughout southern and northern China The$drne large PCR products achieved when using the PCR primers from RV—PJ:PRDV (P japonicus.Japan)and WSBV=PmNOBIII(P.morR~don Taiwan,Chi— na)respectively to amplify the genome from P.chinensis(Tanghai,China)with high fidelity Taq Polymerase.The sequence identities of WSSV from P.chinens~ with those from RV—PJ=PRDV (P 血ponicus,Japan)and WSBV=PmNOBill(P.monodon Taiwan.China)are 97% and 100% respectively,the results provided additiona l evidence that W SSV reported in different parts of the Asian and Pacific regions maybe quite the same or jLISt different variants of the same virus
