An adult female sloth, rescued after being electrocuted, was housed at the Wildlife Section of the Veterinary Hospital (WSVH) of the Institute of Veterinary Medicine (IVM) at the Universidade Federal do Par\u00e1 (UFPA). It was fed a diverse diet that included animal protein, fruits, vegetables, and greens, with vitamin and mineral supplementation. After five years, the sloth was found in its enclosure hyporesponsive, dehydrated, hypothermic, and hyperventilating, with an abdominal dilation of firm consistency. During emergency care, the animal died. Fecal samples collected two days before death were positive only for Clostridium perfringens type A. Necropsy findings included dilatation of the squamous gastric compartment due to gas accumulation, with necrotic and hemorrhagic mucosa, a 180\u2013270\u00b0 volvulus obstructing the gastroesophageal region, and intestinal mucosal hyperemia. Histopathology revealed marked congestion with hemorrhage and gastric mucosal necrosis, along with tertiary lymphoid follicles in the submucosa. To the authors\u2019 knowledge, this is the first report of GDV in a sloth in Brazil. Further research is needed to develop appropriate approaches to GDV in captive sloths.<\/jats:p>","DOI":"10.3390\/ani14233527","type":"journal-article","created":{"date-parts":[[2024,12,6]],"date-time":"2024-12-06T03:44:47Z","timestamp":1733456687000},"page":"3527","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Acute Fatal Gastric Dilatation and Volvulus in a Captive Adult Linnaeus\u2019s Two-Toed Sloth (Choloepus didactylus) in Amazon Biome"],"prefix":"10.3390","volume":"14","author":[{"given":"Hanna Gabriela da Silva","family":"Oliveira","sequence":"first","affiliation":[{"name":"Instituto de Medicina Veterin\u00e1ria, Universidade Federal do Par\u00e1, Castanhal 68740-970, PA, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cinthia T\u00e1vora de Albuquerque","family":"Lopes","sequence":"additional","affiliation":[{"name":"Instituto de Medicina Veterin\u00e1ria, Universidade Federal do Par\u00e1, Castanhal 68740-970, PA, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Let\u00edcia Yasmin Silva","family":"Correa","sequence":"additional","affiliation":[{"name":"Instituto de Medicina Veterin\u00e1ria, Universidade Federal do Par\u00e1, Castanhal 68740-970, PA, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Roberta Martins Crivelaro","family":"Thiesen","sequence":"additional","affiliation":[{"name":"Instituto de Medicina Veterin\u00e1ria, Universidade Federal do Par\u00e1, Castanhal 68740-970, PA, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0074-2488","authenticated-orcid":false,"given":"Rodrigo Otavio Silveira","family":"Silva","sequence":"additional","affiliation":[{"name":"Laborat\u00f3rio de Bacterioses e Pesquisa da Escola de Veterin\u00e1ria, Universidade Federal de Minas Gerais, Belo Horizonte 31270-901, MG, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francisco Alejandro","family":"Uzal","sequence":"additional","affiliation":[{"name":"School of Veterinary Medicine, University of California, Davis, CA 95616, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6017-7647","authenticated-orcid":false,"given":"Sheyla Farhayldes Souza","family":"Domingues","sequence":"additional","affiliation":[{"name":"Instituto de Medicina Veterin\u00e1ria, Universidade Federal do Par\u00e1, Castanhal 68740-970, PA, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7711-6437","authenticated-orcid":false,"given":"Felipe Masiero","family":"Salvarani","sequence":"additional","affiliation":[{"name":"Instituto de Medicina Veterin\u00e1ria, Universidade Federal do Par\u00e1, Castanhal 68740-970, PA, Brazil"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2024,12,6]]},"reference":[{"key":"ref_1","unstructured":"Eisenberg, J.F., and Redford, K.H.
