SUMMARY:

This thesis was divided into a literature review (Chapter 1) and five scientific articles. The general results of the thesis are presented in scientific article 1 and 2. In scientific article 1, 204 white-eared opossum necropsy protocols from the routine of the Veterinary Pathology Laboratory of the University of Brasília (LPV-UnB) and from the veterinary hospital for wild animals at UnB from January 2010 to June 2020. The main causes of death were traumatic, infectious, parasitic and metabolic, respectively. A case of brain toxoplasmosis and a pleomorphic sarcoma were recorded and diagnosed by immunohistochemistry. In scientific article 2, anatomical aspects, lesions of little clinical significance and post-mortem changes recorded in the necropsy routine from August 2018 to June 2020. The following anatomical aspects were listed as baby carrier, mammary papillae, epipubic bone, bifid reproductive tract, scrotal pouch in the inguinal location and cranial to the penis, semi-prehensile tail, absence of claws on the first digit of the pelvic limb, absence of the quadrate hepatic lobe, filiform tongue papillae, absence of hair and labial structure in puppies. As lesions of little clinical significance, infestations by helminths and protozoa such as Physaloptera sp., Sarcocystis sp. and Cruzia tentaculata, smooth muscle hyperplasia in pulmonary arterioles, evidence of the hepatic lobular pattern, body skin abrasions and tail end laceration. As the most common autolytic and putrefactive post-mortem alterations, pulmonary emphysema, intestinal tympanism and pseudomelanosis, pallor of organs and detachment of the epidermis (maceration) were mentioned. Scientific articles 3, 4 and 5 are case reports of specific conditions found in the period and mentioned in scientific article 1. It is concluded that trauma, septicemia and neonatal triad are important causes of death in white-eared skunks in the District Federal. White-eared opossums are susceptible to Toxoplasma gondii and may act as amplifiers of the zoonotic agent in the environment. Finally, the knowledge of anatomical particularities, lesions of little clinical significance and post-mortem changes in domestic and wild animals are useful for the correct diagnostic interpretation and forensic investigations in these animals. However, further characterization work is also needed through the sharing of routine diagnostic experiences.
