Heatmap of (Right and Left) ear necrosis scores throughout the experimental period of Trial 2, using Fusobacterium necrophorum as the inoculum delivered to the left ear of inoculated pigs (n = 10).
Score 0) no visual abnormalities; 1) edema and hyperemia visible, initial lesions, no epithelial erosion or ulceration; 2) the initial swelling erodes through the skin surface to form a scab; 3) necrotic tissue is present; 4) healed lesions with loss of ear tissue.
