Abstract:
Homology of three WSSV isolates, which were sampled from r epresentative maritime space of China: Tanghai isolate (Bo 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-PAG E electrophero grams showed that they were quite same. It suggested that they were the same ki nd of WSSV virus that caused explosive epidemic diseases of shrimps (EEDS) throu ghout southern and northern China. The same large PCR products achieved when usi ng the PCR primers from RV－PJ＝PRDV (P. japonicus, Japan) and WSBV＝PmNOBII I(P.monodon Taiwan, China) respectively to amplify the genome from P.chine nsis (Tanghai, China) with high fidelity Taq Polymerase. The sequence identiti es of WSSV from P. chinensis with those from RV－PJ＝PRDV (P.japonicus, Japan) and WSBV＝PmNOBIII (P.monodon Taiwan, China) are 97% and 100% respect ively, the results provided additional evidence that WSSV reported in different parts of the Asian and Pacific regions maybe quite the same or just different va riants of the same virus.
