Brown snake (Pseudonaja spp.)-induced early cardiovascular collapse is a life-threatening medical emergency in Australia. We have previously shown that this effect can be mimicked in animals and is mediated via the release of endogenous mediators. In the present study, we aimed to purify and characterize the component in Pseudonaja textilis venom which induces cardiovascular collapse following envenoming...
We report a 60 year old male bitten by snakes from the Acanthophis genus (Death adder) on two occasions who developed high titres of human IgG antibodies to Acanthophis venom detected at the time of the second bite. The patient was bitten by Acanthophis antarcticus (common death adder) on the first occasion, developed non-specific systemic effects and did not receive antivenom. Three months later...
Monovalent antivenoms have a lower volume of specific antibodies that may reduce reactions but require accurate snake identification to be used. Polyvalent antivenoms are larger volume and may have a higher reaction rate. However, they avoid the problem of snake identification and may be more cost-effective to manufacture. We have previously shown cross-neutralisation of two Australian elapid venoms,...
Tetrodotoxin (TTX) poisoning is an infrequent but important problem in South-eastern Asia. Despite it being a considerable public health issue in some countries and its potential lethality there continues to be no readily available method for measuring TTX in urine or serum. Previously published methods have used immunoaffinity chromatography, or the conversion of TTX to its C9-base derivative for...
