Comparison of difference in SAA levels in serum between healthy controls and scrapie infected sheep from six to 23/24 weeks of age. Each of the individual five scrapie samples (red dots) and four control samples (blue dots) are presented individually as a single dot to indicate the measured serum amyloid A (SAA) level which is presented on y-axis in μg/ml. At most time points, individual samples in both groups were below the detection range of the SAA kit, and thus the dots appear on top of each other as one single dot at 0.0 μg/ml.
