Pictures of the lesion scores according a 0-3 scale presented by Beer et al. (2020), where in the ceca 0 = no macroscopic alterations; 1 = detectable thickening of the ceca and small lesions on the mucosa, but normal architecture and cecal content; 2 = meaningful cecal wall thickening with some areas of the mucosa presenting hemorrhages and erosions, abnormal architecture of some portions of the ceca, fluid, and yellowish cecal content; 3 = classic typhlitis with thickened cecal walls, severe inflammation, erosions, and total loss of the normal cecal architecture, presence of caseous cores; and in the liver: 0 = no macroscopic alterations; 1 = few localized necrotic areas; 2 = inflammation and presence of circular necrotic areas in some regions of the liver; 3 = severe inflammation and circular necrotic areas approaching confluency on the surface of the liver consistent with the classic “target-like” lesions characteristic of histomoniasis.
