^aClinical score was established after the challenge and was determined by the number of feet presenting FMD lesions plus the presence of vesicles in the snout and/or mouth, 6 being the maximum score. ^bAnimals with no lesions on the feet were PPG. Animals with a delay in the onset of symptoms of disease were PP, and animals with lesions on their feet before 7 dpc were considered NP.
