ELISA reactions of dog sera against L1-GST fusion proteins. Panels A (CPV3 L1 antigen) and B (COPV L1 antigen) show the reactions of 229 dog sera from Switzerland and 315 dog sera from South Africa. Each serum is represented twice, once reacting with CPV3 antigen and once reacting with COPV antigen. In panel C, reference serum reactions are shown. On the x axis, the corrected OD values are shown (see Materials and Methods). Sera giving high OD values are presented on the right, where the scale of the x axis is adjusted to fit all of the results. Sera giving ODs below 0.068 (see Table 1) are in gray, and those giving ODs above 0.068 are in black. The y axis provides the number of sera with a specific OD value.
