Bronchopneumonia caused by Streptococcus equi in a North Atlantic pilot whale (Globicephala melaena)

Bronchopneumonia was observed at the necropsy of a North Atlantic pilot whale (Globicephala melaena). The areas of necrosis were well circumscribed clusters, disseminated throughout the left lung. Streptococcus equi was isolated in pure culture from the lung parenchyma, pharynx and pericardial fluid.
