Passage history and origin of FMDVs used in this study derived from a field isolate, Asia1/JS/CHA/05. The Asia1/JSp1c8 and Asia1/JSM4 population with alternative RGD motifs were occasionally found by two different passage strategies (A and B). Nomenclature used for the passaged viruses is as follows: "p" denotes passage number in pig; "M" denotes passage number in suckling mice and "c" denotes passage number in BHK-21 cells. The virus used for construction of full-length infectious cDNA clone is underlined.
