Antigenic relationships found in cross virus neutralization test of parental (O Manisa) and the cDNA-recovered virus (O Manisa-FG) against FMD viruses originated in East Asia

FMD, foot-and-mouth disease; VNT, virus neutralization test; ME-SA, Middle Eastern-South Asian; SEA, South East Asian; ID, identity.

^a)r₁ values were calculated by division between reciprocal arithmetic titers (serum antibody titer against viruses using for VNT/serum antibody titer against vaccine viruses in the vaccination groups). This experiment was repeatedly tested three times.

^b)Booster at four weeks after first vaccination of commercial monovalent vaccine (high dose of > 6 PD₅₀, Merial Co. Ltd.) and inactivated and oil-adjuvanted O Manisa-FG.

^c)O/ASP/Cathay (phenotype of Genbank accession No. HQ412603).
