Abstract

We characterized the hemorrhagic, coagulant and defibrinogenant activities of Lachesis muta venom and evaluated the capacity of the Brazilian antivenoms in neutralizing these activities. The hemorrhagic activity of L. muta venom was similarly neutralized by Bothrops, Bothrops-Lachesis and Bothrops-Crotalus antivenoms. The coagulant and defibrinogenant activities were better neutralized by the Bothrops-Lachesis antivenom. Bothrops-Crotalus antivenom also neutralized these activities, indicating that it can be an alternative to treat Lachesis envenomations when Bothrops-Lachesis antivenom is unavailable.
