About Prof Lizelle Piater

Envenoming is currently a seriously neglected health issue, especially in Africa, Asia and Latin America, where anti-venoms are not as readily available or reliable as would be believed. In this regard, the World Health Organization estimates that there are approximately 2.5 – 5.4 million snakebites p.a., resulting in roughly 50% envenomation. Of these result in ~ 100 000 deaths p.a., and this figure is roughly a mere third of that relating to secondary injuries including amputations and permanent disabilities. Numbers pertaining to envenoming in Africa account about 22% (580 000) of the global figure – which only relate to reported cases, with 32 000 deaths alone in Sub-Saharan Africa, and not inclusive of the countless numbers of victims who suffer permanent disabilities. As such, our research focusses on the proteomic and biochemical analyses of African venom from various snake species to identify inter- and intra-species profile variations, and subsequently provide greater insight into the manufacturing of anti-venoms. Furthermore, another important point regarding snake venom which ought to be noted, is the fact that not all of the venom composition is toxic. From literature it has been reported that some derivatives thereof can be harnessed and utilised in biomedical applications, in particular anticancer therapeutics.
