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.Na atualidade, a importância das serpentes extravasa a conotação em saúde pública (acidentes ofídicos), e pesquisas promissoras têm demonstrado a utilidade dos venenos das serpentes em diversas áreas como oncologia, diagnóstico, terapia anticoagulante e tratamento da dor. Ainda assim, existem lacunas no conhecimento básico sobre esses animais, tais como a caracterização histológica do seu sistema gastrointestinal, que se tornam obstáculos para estudos nos campos da histologia e patologia comparadas. Nesse contexto, o presente trabalho pretende contribuir com o avanço do conhecimento sobre histologia de serpentes a partir da descrição e análise histológica de amostras do trato gastrointestinal de exemplares das espécies Bothrops jararaca e Crotalus durissus. Para tanto, foram coletadas amostras de 12 indivíduos com até seis meses de idade, seis por espécie (distribuídos igualmente entre machos e fêmeas). A partir dos órgãos colhidos, lâminas histológicas foram preparadas e coradas pela técnica de hematoxilina e eosina, bem como PAS com Alcian Blue. As lâminas foram fotografadas por câmera de alta resolução, resultando em um portfólio representativo da histologia do sistema gastrointestinal desses animais.engUniversidade Federal de Minas GeraisUFMGBrasilVET - DEPARTAMENTO DE CLÍNICA E CIRURGIABrazilian Journal of Veterinary Research and Animal ScienceTrato gastrointestinalHerpetologiaMorfologiaSerpentesDigestive tractHerpetologyMorphologySnakesHistology of the gastrointestinal tract from Bothrops jararaca and Crotalus durissusAspectos histológicos do trato gastrointestinal de Bothrops jararaca e Crotalus durissusinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.revistas.usp.br/bjvras/article/view/133256Izabel Carolina Vargas Pinto GogoneMarcelo Pires Nogueira de CarvalhoKathleen Fernandes GregoSávio Stefanini Sant'annaFrancisco Javier Hernandez-BlazquezJosé Luiz Catão-Diasinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/68725/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALHistology of the gastrointestinal tract from Bothrops jararaca and Crotalus durissus.pdfHistology of the gastrointestinal tract from Bothrops jararaca and Crotalus durissus.pdfapplication/pdf553690https://repositorio.ufmg.br/bitstream/1843/68725/2/Histology%20of%20the%20gastrointestinal%20tract%20from%20Bothrops%20jararaca%20and%20Crotalus%20durissus.pdfe807f17cd2dc91881f06d2c85c9fbc5aMD521843/687252024-05-28 11:55:00.378oai:repositorio.ufmg.br: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Repositório InstitucionalPUBhttps://repositorio.ufmg.br/oaiopendoar:2024-05-28T14:55Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false
