ABSTRACT
Recent studies showed that white spot syndrome virus(WSSV)isolates from different geographic locations share a high genetic similarity except the variable regions in ORF23/24 and ORF14/15,and variable number of tandem repeats(VNTR)within ORF94.In this study,genotyping was performed according to these three variable regions among WSSV isolates collected during 1998/1999 from Southern China.These WSSV isolates contain a deletion of 1168,5657,5898,9316 and 11093 bp,respectively in the variable region ORF23/24compared with WSSV-TW,and a deletion of 4749 or 5622 bp in the variable region ORF14/15 relative to TH-96-II.Four types of repeat units(RUs)(6,8,9 and 13 RUs)in ORF94 were detected in these isolates,with the shortest 6 RUs as the most prevalent type.Our results provide important information for a better understanding of the spatio-temporal transmission mode and the WSSV genetic evolution lineage.
