Nervous signs associated with otitis and cranial osteomyelitis and with Ornithobacterium rhinotracheale infection in red-legged partridges (Alectoris rufa)
A case of nervous signs in red-legged partridges (Alectoris rufa) associated with a severe otitis and osteomyelitis is reported. The outbreak was characterized by abnormal head position, torticollis and difficulty in standing, walking and flying. Pathological, microbiological and molecular
genetic data supported an association with Ornithobacterium rhinotracheale (ORT) infection. Clinical signs persisted for several days and were accompanied by weight loss leading to death. Morbidity was approximately 20% and most birds died if untreated. Lesions were mainly characterized by
a severe osteomyelitis of the cranial bones and purulent inflammation of the external, middle and inner ears. O. rhinotracheale was isolated from ear samples, skull and brain stem in pure culture. Genetic characterization by pulsed-field gel electrophoresis of the clinical isolates showed
that the outbreak was caused by a single strain of ORT. This appears to be the first report of otitis associated with ORT in an avian species.
