【 摘 要 】

ABSTRACT: In Korea, mass mortality occurred among cultured shrimp with visible macroscopic white spots in 2000, and we confirmed the presence of white spot syndrome virus (WSSV) in the tissues of moribund shrimp by electron microscopy. In order toidentify the characteristics of this Korean isolate of WSSV, we cloned and characterized its genomic DNA coding for VP24, VP26, and VP28. On the nucleotide level, VP24, VP26, and VP28 of the Korean isolate were found to be 100%, 100%, and 99% identical tothose of Taiwan, Thailand and Chinese isolates, respectively. On the deduced amino-acid level, all 3 virion proteins showed 100% identity to those of the foreign isolates. The extent of sequence identity suggests that the Korean isolate originated fromthe same ancestor as the Taiwanese, Thai and Chinese isolates.
