INTRODUCTION:

Bothrops snakes are responsible for most of the envenomations in Pará State and Brazil, with acute inflammatory activity and coagulation changes as the main manifestations.

OBJECTIVE:

To report a severe case of envenomation by Bothrops snake occurred in the City of Afuá, Ilha de Marajó, Pará State, in 2015.
