Abstract
Open-access reader
Foot-and-mouth disease (FMD) is endemic in China and is predominantly due to foot-and-mouth disease virus (FMDV) serotype O Mya-98 lineage. In recent years, FMDV O/ME-SA/Ind2001 lineage has spread from the Indian subcontinent to South-East Asia, Middle East and Africa, which may pose potential threats for future trans-regional livestock movements. In this study, we identified the appearance of FMDV O/ME-SA/Ind2001 in China; the first time that this virus lineage has been found there. Sequencing and phylogenetic analysis of VP1 sequences revealed that this newly determined strain belongs to O/ME-SA/Ind2001 sublineage d and is closely related to strains that have caused recent outbreaks of FMD in Nepal, Myanmar, Russia and South Korea. The results suggest extensive movements of the current O/ME-SA/Ind2001 sublineage d viruses and provide essential information for an effective national FMDV control programme in China.
