Otitis media and interna in dairy calves

a retrospective study of 29 cases

Abstract

Otitis media is a common disease in calves. Although its prevalence has not yet been established, it is probably underestimated. Clinical signs of otitis media include a dropped ear caused by facial paralysis, head tilt, and purulent auricular discharge. Prognosis is variable. Poor response to treatment has been reported to be associated with chronicity, intracranial invasion, multisystemic disease and etiological agent. Recently, Mycoplasma spp has been reported as a common cause of otitis in calves. The objective of this retrospective study was to review the epidemiological data, clinical findings, laboratory data, medical imaging results, and outcomes of dairy calves diagnosed with otitis media or interna that were referred to the Centre Hospitalier Universitaire Vétérinaire (CHUV) of the Université de Montréal.
