WildLife Group of the SAVA External Findings • • • • Average body condition (2.5/5) Moderate tick burden No obstructions or injuries to oral cavity No visible signs of external trauma State veterinary services post mortem examination facility Internal Findings • • • • • • • • • • • • Pungent rotten smell Normal skeletal muscle colour and texture Necro-haemorrhagic tracheal lining Severe haemothorax (+- 2-3 litres un-clotted blood in thorax) Moderate haemopericardium Severely autolyzed heart muscle (pale pink in colour with putty like texture) Severe red consolidation of left cranial and caudal lung lobes and right caudo-dorsal lobe. Severely autolyzed kidneys (pulpy), with low amount of peri-renal fat. Severely autolyzed liver (clay like texture) Mildly gas distended GIT with healthy forestomach and intestinal mucosa lining. Normal rumen and intestinal contents. No signs of acidosis (pH:6). No visible internal parasites Exposed kidney in situ Further Results Histopathology showed autolytic changes which may have represented the Clostridial organisms seen on the smears. Additional smears were negative for blood-borne parasites and faecal parasitology showed a low nematode infection (less than 250 eggs per gram). Unfortunately, no aerobic or anaerobic bacterial colonies could be cultured as a result of a logistical mix up between the courier and bacteriology laboratory. This also meant that no PCR typing was possible. Conclusion Although very similar in presentation to anthrax, the clinical and post mortem findings suggested that a Clostridial organism was responsible for the kudu’s death. However, no species could be established definitively and the true cause of death was unknown. Lessons Learnt for Future Investigations Trachea and lungs on cut surface 14 In this investigation, Clostridium spp. was the most likely aetiological agent responsible for the death of the kudu. These bacteria can be cultured and typed provided the samples reach the diagnostic laboratory in sufficient time and under the right transport conditions. In this case study, the correct transport
