An 8-wk-old male, hand-raised, cliff swallow housed in an outdoor aviary had progressive nonspecific clinical signs for 12\u2009d. The bird was euthanized because of poor prognosis. Histologically, histiocytic, lymphocytic, and plasmacytic myocarditis and necrotizing pectoral myositis were noted, with intralesional protozoa in macrophages, myocytes, and the interstitium. Mononuclear mural arteritis in the ascending aorta had similar intralesional protozoa. Ovoid-to-spherical, pale-eosinophilic structures, presumed to be meronts, were found within the endothelial cells of the ascending aorta.
