Distribution of animals classified as positive or negative by ELISA and mean antibody levels during outbreak of sheep scab

Sampling time Positive Negative Other Mean antibody level Range Standard error (SEM)
Pre-outbreak 6 152 2 0.01 0 - 0.11 0.0016

Mid-outbreak 120 34 6* 0.12 0.01 - 1.16 0.01

Post-treatment 90 65 5* 0.08 0 - 0.47 0.0056

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.
