Comparison of WSSV (white spot syndrome virus) DNA using Different oligonucleotide primers

White spot syndrome (WSS) is a viral disease that affects on most of the commercially cultivated shrimp species in worldwide. WSSV causing white spot syndrome in Korea were genetically similar to PRDV in Japan. In this study, we compared PCR products of WSSV with those of PRDV, using their specific oligonucleotide primers. As a result of sequence analysis, amplified PCR products were almost identical to the described sequences used in this experiment. Therefore, the results obtained in this study suggest that WSSV causing white spot syndrome in Korea were genetically similar to PRDV in Japan. Naturally, more detailed studies will be needed to identify the taxonomic correlation between these viruses.
