Anatomopathological findings of Testudines necropsied in the Distrito Federal, Brazil

Abstract

In order to determine the main anatomopathological findings of Testudines necropsied in the Distrito Federal, all necropsy records performed at the “Laboratório de Patologia Veterinária” of the “Universidade de Brasília” (LPV-UnB) on Testudines during the period from January 2008 to July 2020 were reviewed. The 72 cases reviewed were grouped and classified according to species, sex, origin, season of occurrence, and diagnosis. In 69.44% of the cases the species was informed in the necropsy protocols, which included Phrynops geoffroanus (38%), Trachemys dorbigni (36%), Chelonoidis carbonaria (14%), Chelonoidis denticulata (10%) and Podocnemis expansa (2%). In 30.55% of the cases this parameter was not informed and were classified only as Testudines. In 41.66% of the cases the sex was informed, being female 22.22%, male 19.44%, and 58.33% were not informed. Of these animals 79.16% were from environmental agencies and 20.84% from zoos and/or guardians. In 70.83% of the animals analyzed they were directly related to the autumn and winter seasons, with June being the most frequent month (29.17%). The conclusive diagnosis was possible in 68.05% of the cases. The category of disorders caused by injurious agents (48.97%) was the most prevalent, followed by inflammatory disorders (32.65%) and nutritional and metabolic disorders (28.57%). The main diagnoses were carapace and/or plastron fracture with 30.61%, hepatic steatosis (20.40%) and pneumonia (10.22%). Most cases of carapace or plastron fracture and hepatic steatosis occurred in animals from environmental agencies.

Histopathological Perspectives of Multiple Organs in a Red- Footed Tortoise (Chelonoidis carbonaria) with Suspected Metabolic Bone Disease: A Case Report

“…Some of the health issues that tortoises in captivity can face include respiratory ailments caused by bacterial or viral infection, [7][8][9][10] gastro-intestinal disease caused by parasite or viral infection, 8,11,12 and nutritional and metabolic disorders. [13][14][15] Metabolic bone disease (MBD) is one of the metabolic disorders commonly seen in captive reptiles, particularly in Chelonia (turtles, tortoises, and terrapins) and lizards, occasionally in snakes. 16 In veterinary medicine, MBD refers to a group of pathological conditions that affect the integrity and function of multiple bones.…”

Multiple hoof fractures in a water tiger (Trachemys dorbigni): case report

“…Quando atingem a fase adulta esses valores mudam bruscamente passando a ser aproximadamente 90% de origem vegetal e 10% carnívora (Bager, 2003). Santos et al (2022) determinando os principais achados anatomopatológicos de morte em Testudines no Distrito Federal, observou que fraturas de carapaça causadas por agentes físicos foram os diagnósticos com maior frequência em necrópsias. Segundo Barten (2006) e Melidone & Selleri (2008), as alterações traumáticas que causaram fraturas de casco em Quelônios foram as mais representativas em seus estudos, sendo consequência de acidentes automobilísticos, mordidas por animais predadores, e quedas.…”
