Envenomation by the Malagasy colubrid snake Langaha madagascariensis

This report documents a case of envenomation by a Malagasy opisthoglyphous snake, Langaha madagascariensis. The snake bit the finger of a healthy adult man who was attempting to record its morphological measurements as part of a biodiversity survey which was being conducted in the extreme north of Madagascar. Symptoms of this case included severe local pain accompanied by observable swelling which lasted for several days. The present observations indicate that bite by L. madagascariensis potentially causes notable physiological effects in humans although the snake is generally calm and reluctant to bite unless provoked.(AU)

Envenomation by the madagascan colubrid snake, Ithycyphus miniatus

We report two cases of envenomation by a Madagascan opisthoglyphous snake, Ithycyphus miniatus. In both cases, the snake bit the finger of a human who was preparing an experiment by tying a string around the snake body. Symptoms of the first case included temporal severe local pain and extensive bleeding. In the second case, severe pain accompanying obvious local swelling was caused and lasted for several hours. The present observations indicate that bite by I. miniatus potentially causes serious physiological effects in humans although the snake is basically calm and reluctant to bite.
