Abstract

Snake venoms are the most studied animal toxins. The variability of venom composition was described not only intra- and interspecies but also according to sex, age and geographical distribution of the snakes, and in most studies the diet of snakes was considered as the triggering factor for this variation. The Herpetology Laboratory of the Butantan Institute provides venoms for antivenom production and for scientific research not only for the Institute, but to other institutions as well. Currently, it is observed that the number of snakes donated to the Institute has been steadily decreasing. This fact has stimulated the Herpetology Laboratory, where the snakes are kept, to develop technics to reproduce snakes in captivity and to become self-sufficient in creating these animals. Thus, the snake's colony of Herpetology Laboratory is composed mostly by animals born and/or kept in captivity for a long period of time and fed exclusively with mice and/or rats. Considering that the presence of changes in venom composition of snakes kept in captivity has not yet been investigated, the aim of this study is to evaluate the influence captivity maintenance on composition of B. jararaca snake from Herpetology Laboratory of Butantan Institute. This study involves the biological and biochemical characterization and comparison of venoms from captive and wild snakes.
