Abstract

The current report describes granulomatous pneumonia due to Spirocerca lupi in 2 free-ranging maned wolves ( Chrysocyon brachyurus). Both wolves had multiple, white, 1–1.5 cm in diameter, soft, encapsulated granulomas in the caudal lung lobes, which contained centrally placed parasites on cut sections. Microscopically, there was granulomatous inflammation with numerous intralesional sections of spirurid nematodes. Representative complete adult specimens of nematodes derived from these lesions were submitted for parasitological exam and identified as the spirurid S. lupi. To the authors’ knowledge, there have been no published reports of S. lupi in maned wolves.
