Specific humoral immune response induced by FMDV infection. Neutralizing antibody titers in log₁₀ (A) and presence of antibody levels against FMDV non-structural proteins (NSP) (B), induced by SAT1, SAT2 and SAT3 FMDV infected animals by needle infection (blue lines, round symbol) or by contact challenge (pink, square symbol). NSP results are expressed by percentage of inhibition (PI) and cut-off is determined at 50% (dash line). Graphs represent the mean and SEM for each group at each time point.
