A 7-year-old Thoroughbred gelding presented with muscle fasciculation, reluctance to move, profuse sweating, tachycardia, tachypnoea and a localised, unilateral swelling on the muzzle. History and physical examination were suggestive of snake envenomation.
A sandwich ELISA for the detection of snake venom was performed on serum and urine samples.
The test performed on urine confirmed a diagnosis of tiger snake envenomation.
The response to treatment with antivenom and supportive medical therapy was excellent.
