First detection of foot-and-mouth disease virus O/ME-SA/ Ind2001e sublineage in Jordan

Foot-and-mouth disease (FMD) is a highly contagious vesicular disease that is caused by the FMD virus (FMDV). This disease affects both wild and domestic cloven-hoofed animals, and the latter of which includes cattle, swine, sheep and goats. FMD is endemic to Jordan and has a severe impact on the productivity of domestic livestock. In January 2017, FMD outbreaks were detected in different animal species across Jordan, resulting in high mortality rates among young lamb and goat populations as well as causing classic FMD symptoms in cattle. In this study, clinical specimens were collected from animals affected by FMD. The results obtained from sequencing the VP1 gene place the studied FMDV isolate within the FMDV O/ME-SA/ Ind2001e sublineage. Phylogenetic analysis of VP1 suggests that the O/JOR/1/2017 isolate is very similar to that of viruses isolated from Saudi Arabia in 2016. The possible introduction of this strain to Jordan might occur through transboundary animal movement or other transmission routes from Saudi Arabia, a neighbouring country.
