O presente relatório foi desenvolvido no âmbito do Estágio Curricular da Licenciatura
em Enfermagem Veterinária, realizado na empresa VetManos, Lda., entre 23 de fevereiro
e 18 de maio de 2026. O estágio decorreu em contexto de medicina veterinária de
produção, permitindo o acompanhamento de atividades relacionadas com medicina
preventiva, sanidade animal e clínica médica de espécies pecuárias. Durante o período
de estágio foram registados 22 666 procedimentos, dos quais 99,73% corresponderam
a ações de medicina preventiva, com predominância das espécies bovina e ovina. Entre
as atividades desenvolvidas destacou-se a participação em duas necrópsias de bezerros
com diagnóstico presuntivo de leptospirose, que constituíram a base do presente
trabalho. Foram observadas alterações macroscópicas compatíveis com um processo
sistémico grave, nomeadamente icterícia generalizada, hemoglobinúria, nefromegália e
alterações hepáticas. A observação destes achados permitiu relacionar as lesões
identificadas com os mecanismos patogénicos da leptospirose bovina e compreender a
relevância da necrópsia como ferramenta de apoio ao diagnóstico presuntivo em
situações de morte súbita. O estágio contribuiu para o desenvolvimento de
competências técnicas e científicas em enfermagem veterinária, promovendo a
integração entre os conhecimentos teóricos adquiridos ao longo da formação e a prática
profissional. Conclui-se que a necrópsia constitui um procedimento fundamental para a
investigação de surtos, para a implementação de medidas sanitárias adequadas e para a
proteção da saúde animal e da saúde pública.
This report was developed within the scope of the Veterinary Nursing Degree internship carried out at VetManos, Lda., between 23 February and 18 May 2026. The internship took place in a production animal veterinary setting, providing exposure to activities related to preventive medicine, animal health programmes and clinical practice involving livestock species. During the internship, 22,666 procedures were recorded, of which 99.73% corresponded to preventive medicine activities, predominantly involving bovine and ovine species. Among the activities performed, participation in two calf necropsies with a presumptive diagnosis of leptospirosis was particularly noteworthy and formed the basis of the present report. Macroscopic lesions consistent with a severe systemic disease process were observed, including generalized jaundice, haemoglobinuria, nephromegaly and hepatic alterations. These findings enabled the association of the observed lesions with the pathogenic mechanisms of bovine leptospirosis and highlighted the relevance of necropsy as a valuable tool supporting presumptive diagnosis in cases of sudden death. The internship contributed to the development of technical and scientific competencies in veterinary nursing, promoting the integration of theoretical knowledge acquired throughout the degree programme with professional practice. It can be concluded that necropsy represents a fundamental procedure for outbreak investigation, the implementation of appropriate sanitary measures and the protection of both animal and public health.
