    Haemonchus Contortus como causa de atrofia gelatinosa cardíaca em caprino: Relato de caso
    (Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) TEIXEIRA, Luiza Ramos; OLIVEIRA, Braian Rombaldo de; MARTINELLI, Paulo Edson Baptista; ESTEVAM, Kamile Jorge; SANTOS, Gabriele Araújo Rodrigues dos; BIRGEL, Daniela Becker; BIRGEL JÚNIOR, Eduardo Harry
    Haemoncosis is an important parasitic disease that normally affects sheep and goats and is caused by the nematode of the genus Haemonchus, of the Trichostrongyloidea family. Its evolutionary cycle has a period of development in the host, called the parasitic phase, and another called the environmental phase. This parasite is known for its extreme resistance to anthelmintics, becoming a major problem for goat and sheep farming. The control of haemoncosis depends on early awareness by the producer, monitoring the proliferation of H. contortus and management protocols and prophylactic measures such as anthelmintic treatments. The clinical signs observed are anemia, apathy, hypoproteinemia, anorexia, dehydration, weight loss, generalized edema and decreased milk production. Among the necropsy findings, gelatinous atrophy of cardiac fat can be seen, which is normally observed in cachectic animals, or those undergoing some process of carbohydrate deprivation, or any process that results in an abrupt loss of body weight, requiring the use of lipid reserves, initiating a process of lipolysis and mobilization of this fat for ATP synthesis. The present study aims to report a case of haemoncosis in a goat in which gelatinous cardiac atrophy was observed as one of the necropsy findings.

    Retículo esplenite traumática associada á peritonite em bovino: Relato de caso
    (Centro Universitário da Fundação de Ensino Octávio Bastos, 2024-10-09) OLIVEIRA, Braian Rombaldo de; TAGLIAFERRO, Karoline Saturnino; ALVISI, Renato Duarte; FREITAS, Renan Contini de; FAGUNDES, Juliana Portela Gonçalves; MELO, Larissa Martarella de Souza; BIRGEL, Daniela Becker; BIRGEL JÚNIOR, Eduardo Harry
    The ingestion of foreign bodies by ruminants is the result of non-selective feeding, the anatomy of the fore-stomachs and the presence of sharp objects in pastures. Traumatic reticulo-splenitis is a disease with low frequency in ruminant clinical practice. It occurs due to the ingestion of sharp foreign bodies, which causes perforation of several organs in the abdominal cavity. The proximity of the reticulo-splenitis to several organs, associated with the presence of sharp objects in pastures and feeders are important factors to be analyzed, which cause several pathological processes, including traumatic reticulo-pericarditis, traumatic reticulo-peritonitis, traumatic reticulo-hepatitis and traumatic reticulo-splenitis. There are no characteristic clinical signs of traumatic reticulo-splenitis, nor specific diagnostic methods, where the spleen of cattle, for example, cannot be examined through transrectal palpation. When ingested by the animal, the sharp object follows the flow of the food bolus and remains trapped in the reticulum, where, through physiological contraction, it can perforate the organs adjacent to it. After this, the object can perforate other organs, carrying microorganisms to the site of the injury, causing an infection and malfunction of the organ. Therefore, the present study aims to report a case of traumatic reticulum splenitis in a bovine.
