Which form(s) of African Horse Sickness are described based on postmortem lesions?

At necropsy, African Horse Sickness forms are characterized by the pattern of lesions seen, allowing three forms to be described. The pulmonary form shows heavy, congested lungs with edema and air-space changes; the cardiac form features myocarditis and pericardial/epicardial involvement with heart edema; the mixed form displays a combination of both pulmonary and cardiac lesions. Because necropsy can reveal either or both sets of lesions, all three forms—pulmonary, cardiac, and mixed—can be described on postmortem examination.
