Fatal self-envenomation in a brown tree snake, Boiga irregularis, from south-east Queensland.

The case history and clinical signs of a fatal self-envenomation event by a brown tree snake, Boiga irregularis, in South-east Queensland, Australia, are presented. Clinical signs began 20 minutes post-envenomation with muscle twitching, ataxia, and heat seeking behavior which progressed to partial paralysis by 6 hours, generalised paralysis and respiratory arrest at 10 hours and cardiac arrest by 12 hours post-envenomation. Clinical signs are suggestive of potent neurotoxicity for B.

Exercise-induced deep pectoral necrosis in white-headed pigeons (Columba leucomela).

Abstract: Two white-headed pigeons (Columba leucomela) developed deep pectoral myopathy 2 days after vigorous exercise associated with capture. Clinical signs included lethargy and an inability to raise the wings above the head. Gross pathology consistently revealed marked pallor and edema of the supracoracoideus muscle, and histopathology revealed severe myofiber degeneration.
