Abstract： In this study, a virus was isolated from the feces of a pig farm in Baoding, Hebei
Province, which could proliferate on Vero cells and showed significant cytopathic changes after
Fifth passages. The isolate strain was identified and sequenced to be PEDV and named HBLX.
Genetic analysis of Sgene of HB-LX strain was analyzed by DNA Star software. The results
Showed that the HB-LX shared 92.4% identities with vaccine CV777, shared
92.2% and 92.7% identities with the field strain MK and 83P-5, and shared more than 97% identities
With the current in in China. HB-LX and China's CHCCC, GJL, PJ1407and
South Korea's AS01, KPV1402 and other genetic relationship recently.
