ASPIRATION BRONCHOPNEUMONIA BY ACINETOBACTER BAUMANNII IN A WILDLIFE EUROPEAN HARE (LEPUS EUROPAEUS) IN BRAZIL

Acinetobacter baumannii is a major cause of illness in hospitalized patients and the most important and common pathogen in nosocomial outbreaks worldwide. In animals, A. baumannii has been associated with respiratory infections in a group of minks, leading to pneumonia and acute mortality. This report documents a case of aspiration bronchopneumonia in a wild European hare caused by A. baumannii. A free-ranging, adult male European hare was submitted to necropsy after acute trauma due to being hit by a car. Its lungs showed consolidation with abscess in the middle and cranial lobes. Histopathologic evaluation revealed liquefactive necrosis associated with neutrophilic infiltration, cellular debris, plant material, and bacterial myriads surrounded by moderate neutrophils, macrophages, multinucleated giant cells, lymphocytes, and plasma cell inflammation. Acinetobacter baumannii was isolated from lung tissue.
