Abstract

Recent studies have discussed the importance of snakes, going beyond the context of Public Health (snakebites). Promising research demonstrates the utility of snake venom in several fields, including oncology, diagnosis, anticoagulant therapy, and pain treatment. Nevertheless, there are still gaps in the basic knowledge on these animals, specifically regarding the histological characterization of the gastrointestinal tract, which ultimately hinder comparative histology and pathology studies. In this context the present study intends to contribute with the advance of current knowledge on snake histology by describing and analyzing histological samples of the gastrointestinal tracts of Bothrops jararaca and Crotalus durissus. Samples were collected from 12 individuals (six from each species), up to 6 months of age and equally distributed between males and females. Histological slides were prepared from the organs collected and were stained with hematoxylin and eosin, periodic acid-Schiff and alcian blue. The slides were photographed with a high-resolution camera to create a portfolio representative of the histology of the gastrointestinal systems of these animals.
