Traumatic pericarditis caused by a bamboo twig in captive waterbuck (Kobus ellipsiprymnus)

A 19-year-old captive male waterbuck (Kobus ellipsiprymnus) exhibited traumatic pericarditis at necropsy. The animal weighed 182 kg at necropsy and revealed no remarkable findings in external observation. Severe pericardial adhesions with fibrosis, hepato-diaphragmatic adhesions, straw-colored ascites and hepatosplenomegaly were observed upon examining the internal organs. Perforations made by a 12-cm-long sharp-ended bamboo twig were detected in the reticulum, diaphragm, pericardium, lung and liver. Trueperella pyogenes was identified in pericardial fluid. To our knowledge, this is the first documented case of traumatic reticulopericarditis caused by a sharp-ended bamboo twig in a captive waterbuck.
