Abstract

A 14-year-old female captive Asian elephant in a Malaysian zoo with a history of positive sero-reactivity to Elephant TB

STAT-PAK assay was humanely euthanized due to chronic weight loss and poor response to treatment. Postmortem revealed

generalized congestion and emphysematous lungs. Microscopically, there were severe pulmonary emphysema, eosinophilic hyaline

membrane and infiltration of mature fibrocytes in the alveolar walls. Based on the histopathological findings interstitial pulmonary

fibrosis was diagnosed. The possible cause of which although not completely known, is most likely due to hypersensitivity. The

allergic reaction could have been caused by exposure to antigens of avian origin or the Mycobacterium gilvum, an non-tuberculous

mycobacterium (NTM), isolated from the lung. This is the second case reported in elephants globally, thought it has been well

studied in humans and reported in horses. Providing good husbandry for elephants in captivity is important to reduce the occurrence

of such condition.
