Envenomation by a spotted black snake (Pseudechis guttatus), following multiple bites on the buccal mucosa of a captive maned wolf (Chrysocyon brachyurus), caused the animal's collapse, hemolysis, rhabdomyolysis, local tissue necrosis, hepatic and renal failure, and subsequent death. The wolf died despite intensive supportive care including antivenom administration, fluid support, and a blood transfusion. Gross necropsy findings included myocardial and intestinal hemorrhage, pulmonary congestion, hepatomegaly, and splenomegaly. Microscopic examination of formalin-fixed tissues demonstrated pulmonary and abdominal visceral hemorrhage, acute nephrosis with casts, multifocal hepatic necrosis, and splenic congestion.
