Figure 2. West Nile virus (WNV) Absorbance attributed to specific WNV antigen immuglobulin (Ig) M interaction in the West Nile Equine IgM Capture enzyme-linked immunosorbent assay (ELISA) on individual horses. The open circle (o) is the a.m. reading, the plus (+) is the p.m. reading, and the filled-in circle is the last reading (all a.m., hence the circle) before the horse was euthanized. Each number corresponds to the horse number.
