title: Otitis interna as a result of Pasteurella multocida infection in a laboratory woodchuck.
abstract: A laboratory woodchuck presented clinically with left-sided torticollis and a purulent exudate within the external auditory meatus of the left ear. Bacterial culture of the exudate resulted in a heavy growth of Pasteurella multocida. Treatment was initiated with topical and systemic antimicrobial compounds. There was no clinical improvement after 72 h of treatment, and euthanasia was elected. Radiographs correlated well with necropsy findings, confirming a diagnosis of otitis media; otitis interna was not confirmed but was suggested by the clinical presentation. To the authors  knowledge, this is the first description of otitis media/interna as a result of P. multocida infection in a laboratory woodchuck.
