Numbers of animals classified as positive or negative for sheep scab based on their ELISA results throughout the outbreak. Positive animals classified as having an OD450 value > 0.06. Also shown are the mean ELISA OD450 values, the range of values across all 160 animals throughout the outbreak of sheep scab and the standard error associated with each mean.*1 animal died of an unrelated cause, other samples unavailable due to unobtainable serum samples.
