摘要：

Bothrops lanceolatus is an endemic viperid species in the Lesser Caribbean island of Martinique. Envenomings by this species are characterized by local and systemic effects, among which the development of thrombosis in various organs is the most severe complication. An experimental toxicological characterization of this venom was performed using in vivo mouse tests and various in vitro assays. The venom induced lethal, local and systemic hemorrhagic, edema-forming, myotoxic, thrombocytopenic, proteinase and phospholipase A(2) activities. The preclinical efficacy of a batch of monospecific Bothrofav antivenom currently in use in Martinique was assessed. The antivenom was highly effective in the neutralization of all activities tested, in agreement with its described clinical efficacy. This batch of antivenom showed a higher preclinical efficacy as compared to a previous batch used in the past. (C) 2018 Elsevier Ltd. All rights reserved.
