- Abstract
Bluetongue (BT) is one of the most important insect-borne, non-contagious viral diseases of ruminants and can cause severe disease and death in sheep. Its pathogen, bluetongue virus (BTV) has a double-stranded RNA genome consisting of 10 segments that provides an opportunity for field and vaccine strains of different serotypes to reassort whilst simultaneously infecting the same animal. For the first time, we report the full-length genome sequence of a BTV strain of serotype 21 (5149E) isolated from sentinel cattle in Guangxi Province in China in 2015. Sequence analysis suggested that the isolate 5149E had undergone a reassortment incident and acquired seg-6 from an isolate of BTV-16 which originated from Japan. This study aims to provide more understanding as to the origin and epidemiology of BTV.
