title: Bilateral Granulomatous and Fibrinoheterophilic Otitis Interna due to Pseudomonas aeruginosa in a Captive Little Bustard ( Tetrax tetrax ).
abstract: A captive juvenile little bustard ( Tetrax tetrax ) was presented for acute onset of right head tilt and right circling. The bird failed to respond to supportive care and systemic antibiotic therapy. A bilateral granulomatous and fibrinoheterophilic otitis interna due to Pseudomonas aeruginosa was diagnosed postmortem by histopathologic examination and bacterial culture. In bustards, Pseudomonas species have been documented in the normal bacterial flora of the oropharynx and are frequently reported in upper respiratory tract infections. This is the first report of a peripheral vestibular syndrome due to P aeruginosa otitis interna in a bustard species. Pseudomonas aeruginosa should be included as a possible cause of otitis and peripheral vestibular syndrome in bustards.
