The bites of six species of venomous elapid snakes in Central Province Papua New Guinea produce similar clinical syndromes. Optimal management of envenomed patients involves the use of monospecific antivenom. In this study, Venom Detection Kits (VDKs) (CSL Diagnostics, Melbourne) were used to try to make a specific diagnosis in envenomed patients at their admission. VDKs detected venom in admission bite site swabs from 39 to 46 patients (85%). Thirty-eight of these patients were shown to have been bitten by taipans. In all cases where venom was detected by the VDK, this correlated with subsequent laboratory enzyme immunoassay results. Selective use of VDKs in Central Province could allow more widespread use of monospecific antivenoms and produce considerable financial savings.
It was found that bee (Apis mellifera) venom, red-back spider (Latrodectus mactans) venom, blue-ringed octopus (Hapalochlaena maculosa) venom, ten different snake venoms, phospholipase A2 and four snake toxins caused sphero-echinocytosis of human red blood cells at 200 ng/ml. Most venoms and toxins lost the ability to deform human red blood cells when their components of less than mol. wt 10,000 were applied. In a number of cases the sphero-echinocytotic effect was also inhibited by blood sera of Notechis scutatus and Pseudonaja textilis.
