Necropsy and histopathological research in swine salmonellosis

The study was conducted between October 2021 and February 2023 through the necropsy at the Discipline of Forensic Medicine and Necropsy Diagnosis of F.M.V. Timisoara of 87 pig cadavers aged between one week and 12 weeks, sampled from the intensive breeding system, in order to elucidate. the cause of death, of which 61 presented gastrointestinal lesions of an inflammatory nature. After evisceration, a thorough macroscopic examination of the organs under study was carried out. We took samples from the gastrointestinal mass for histopathological examination. This examination involved the recording of modified structural features (shape, size, colour, appearance, lobulation, consistency, and section examination) and the collection of samples for microscopic examination. The obtained histopathological preparations were examined under an Olympus Cx41 microscope with increasing magnifications (x6, x10, x20, and x40), the most significant lesions were microphotographed. Of the 87 necropsied pig carcasses aged between one week and 12 weeks, 61 (70.11%) presented gastrointestinal lesions of an inflammatory nature, and 48 (55.17% of the carcasses and 78.68% of corpses with gastroenteropathies) took on the appearance of haemorrhagic and fibrino-haemorrhagic inflammation. For an even more accurate diagnosis of salmonellosis, as well as to confirm the diagVeterinary Medicine in Timisoara.
