Left panel depicts typical delayed-type hypersensitivity (DTH) reaction appearance on dorsum of cat. Triplicate series of each antigen were injected (0.1 ml/injection). From left to right: ovalbumin (OVA), PBS, keyhole limpet hemocyanin (KLH). Right panel shows DTH scoring algorithm, with each reaction scored from 0–5. Mean DTH score was calculated for each antigen for each cat.
