From: Capsid coding sequences of foot-and-mouth disease viruses are determinants of pathogenicity in pigs
Viral RNA in oral swab samples, from individual pigs, measured by quantitative real-time RT-PCR and expressed as threshold cycle (Ct) values (note when no Ct value was obtained by 50 cycles then a value of 50 was used). Inoculated pigs = filled symbols and solid lines, in-contact pigs = open symbols and dotted lines. Swab 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 and selected samples were assayed. † 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).
