FMDV serotype specific (O or A) antibody response in serum expressed as blocking percentage derived from solid phase blocking ELISA. Diagnostic cut-off level is 50% for serotype O and 45% for serotype A. Inoculated pigs = filled symbols and solid lines, in-contact pigs = open symbols and dotted lines. Blood samples were collected on dpi 0, 1, 2, 3, 4, 5, 7 and 10 for inoculated pigs and on dpi 0, 4, 5, 6, 7, 8, 9 and 10 for contact pigs. † indicates death or euthanasia for welfare reasons. Panel A: Group 1 (O1K B64), panel B: Group 2 (O1K/A-TUR), panel C: Group 3 (O1K/O-UKG), panel D: Group 4 (O-UKG/34/2001).
