First Finding of Southeast Asia Topotype of Foot-and-Mouth Disease Virus inKinmen, Taiwan, in the 2012 Outbreak

[摘要] References(23)Foot-and-mouth disease virus,a member of genus Aphthovirus within the familyPicornaviridae, affects cloven-hoofed animals, causing foot-and-mouthdisease characterized by vesicle development. The Southeast Asia topotype, one of thetopotypes within serotype O of the virus, is prevalent in some Asian countries, but hadnot previously been found in Taiwan. The topotype was first found in pigs in KinmenIsland, Taiwan, in 2012 and identified by nucleotide sequence comparison and phylogeneticanalysis. Outbreaks were reported at 4 farms, resulting in the culling of 628 pigs and 1cattle. Pigs were the only species infected during the outbreak. The incursion ofSoutheast Asia topotype into Taiwan implies the expansion of the topotype in EastAsia.
