Characteristics of the chimeric foot-and-mouth disease virus with SAT viruses P1 (VP1–4), 3B and 3C mutation. a Schematic depiction of the chimeric viruses expressing structural proteins of SAT1, SAT2, and SAT3 viruses: SAT1 BOT 1/68 (AY593845), SAT2 ZIM 5/81 (EF134951), and SAT3 ZIM 4/81 (KX375417). The infectious cDNA clone is O1 Manisa, with a format of 3B3B3B3 in the 3B region and C142T in the 3C region. b Images of chimeric virus particles (SAT1 BOT-R, SAT2-ZIM-R, and SAT3-ZIM-R) via electron microscopy. The bar represents 100 nm. c Identification of recombinant FMDV structural proteins (SAT1, SAT2, SAT3) using antigen ELISA
