Survival times in relation to ages at infection. Survival time (X axis in days, mean ± SD) of orally dosed sheep (solid symbols; squares, 5 g dose and circle, 1 g dose) and naturally exposed progeny (open symbols) in relation to their age at exposure (Y axis in days, mean ± SD; for naturally exposed progeny, the age has been arbitrarily defined as around birth). Black, ARQ Suffolk sheep; blue, ARQ Romney sheep, green, VRQ Cheviot sheep; red, AHQ Cheviot sheep. Note that (1) the survival times of orally dosed AHQ Cheviot sheep are similar (low standard deviation) despite noticeable differences in age at exposure (see Table 1 for details) and (2) the survival times of orally dosed sheep are similar to those of naturally exposed progeny of the same breed and genotype.
