  1. The approximate depth of the hypoechoic area was determined from videos of the sonograms. Visible lesions indicative of OPA at PME were classified as follows: affecting > 40% of the lung (Adv), affecting 10–40% of the lung (Mod), affecting < 10% of the lung (Early), > 3 consolidated lesions (Pos?), 1–3 discrete consolidated lesions < 1 cm (Neg?), No visible lesions (Neg). LF: Volume of lung fluid collected by tipping after euthanasia. BCS: body condition score (scale 1–5). OPA histo: histological confirmation of OPA status. Other path: signs of bacterial (b) or parasitic (p) pathologies by gross PME and/or histopathology, pleurisy (pl)
