[Venomous and poisonous animals--I. Overview]

Abstract

Venomous animals that are able to innoculate or inject venom and poisonous animals that cannot inject venom but are toxic when ingested belong to all zoological groups. They can be encountered worldwide in any ecosystem on land and at sea but they are more common and more dangerous in tropical areas. This first article of a series to appear in the next issues of Medecine Tropicale presents an overview of species involved in envenomations and poisonings. In addition to a brief reviewing geographic risks and circumstances in which bites, stings or ingestion occur, some information is provided about antivenim therapy, the only etiological treatment.
