Colic syndrome in horses is characterized as pain of acute abdominal origin, which can originate from various diseases in abdominal organs, however, in the vast majority of cases, the origin of the pain is disorders in the gastrointestinal tract (GIT). Among these diseases of the GIT is the displacement of the left ascending colon and its incarceration over the nephrosplenic ligament. This displacement is characterized by the entrapment of the pelvic flexure in the nephrosplenic ligament, and the main predisposing factor for this to occur are the muscles themselves. anatomical characteristics of the region. This condition can lead to mild, moderate or severe pain, causing physical changes, mainly in heart rate, respiratory rate and intestinal motility pattern. Diagnostic methods for nephrosplenic incarceration include the association of findings on physical examination, transrectal palpation and transabdominal ultrasound examination. However, it is worth highlighting that, in certain cases, only the surgical procedure confirms the diagnosis. In the case of an established clinical diagnosis, the main drug therapy applied to these cases is the administration of epinephrine in the form of an infusion, in an attempt for this alpha-2 adrenergic agent to lead to splenic contraction, and the ascending colon to return to its normal anatomical position. . In some cases, this attempt at splenic contraction does not produce positive results, leaving the surgical procedure as the only treatment. The objective of this work is to address, through a literature review, the main aspects of the nephrosplenic entrapment in horses, through a clinical and surgical approach taking into account tells current literary data.

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.
Malformações congênitas em bezerros decorrentes do consumo do bagaço de maçã na alimentação de vacas prenhes na região sul do país: Revisão de literatura

Apple pomace is widely used in cattle feed in most of the southern region of Brazil, and is composed of peels, stalks, leaves, seeds and pulp, with components such as fiber, sugars, low levels of lipids, proteins, vitamins and minerals. This product has been linked to congenital malformations in calves, resulting from the ingestion of pomace by the pregnant mother, although there is no evidence that this relationship actually exists. However, after several studies, it was found that it is not the apple pomace itself that causes the malformation, but rather the components present in this pomace, which may be pesticides used in apple production and cultivation that can cause mutagenicity, as well as mycotoxins that also cause mutagenicity. Another possible cause is manganese deficiency, due to excessive ingestion of apples, which have low levels of manganese in their pulp. The malformations caused by this are chondrodysplasia and dwarfism, and these diseases are recognized as diseases that hinder the growth and development of the animal, due to the conditions in which the animal is born, such as short, curved, rigid bones, and coarse joints. It is also possible to find malformations in organs, thus preventing their proper functioning. Thus, the objective of this work is to compile data from the literature, addressing the main causes of congenital malformations in calves from pregnant cows fed apple pomace in the southern region of the country.
Métodos diagnósticos da endocardite bacteriana em cães: revisão de literatura

Bacterial endocarditis is an infectious process that affects the heart valves, most commonly, mitral and aortic located on the left side, or the endocardium itself. The animals The most affected are medium or large male dogs, due to the occurrence of prostatitis subacute or chronic bacterial infection, which can also affect small dogs, both males and females. In most cases, the clinical signs of the disease are not specific (such as hyperthermia, weight loss, loss of appetite, polydipsia, polyuria, tachypnea, dyspnea, and exercise intolerance), which makes early diagnosis even more difficult. Positive blood culture results are used as diagnostic methods, along with the relationship between the most involved microorganisms, as well as echocardiography, electrocardiogram, radiography, blood count and necropsy. Among the treatment methods, the recommended therapeutic protocol is the use of broad-spectrum antibiotics that penetrate fibrin, always maintaining them for long periods, and can be administered intravenously and orally, always following the results of the blood culture and antibiogram, without ever forget to periodically evaluate possible coexisting problems that may appear as a result of bacterial endocarditis. Therefore, the objective of this work is to compile data from the literature, highlighting the different methods for diagnosing bacterial endocarditis.

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.
Torção de raiz do mesentério em equino isquemia e reperfusão: Revisão de literatura

Mesenteric root torsion is a disease in which the mesentery root rotates. It can be explained by the large length of the horse's intestine, its anatomical positioning and variations in the intestinal lumen. It can even be correlated with the species' own intestinal anatomy and is characterized by the rapid formation of gases in the intestinal lumen (resulting from microorganisms present in the intestine and as a consequence of the ingestion of highly fermentable substances). Another important factor is the characteristic of its diet, with the fermentation process being an important part of its digestion, indirectly promoting the distension of intestinal loops. This condition can cause severe vascular impairment and lead to severe hypoxia, which can trigger cellular damage and consequent cell death and tissue necrosis. The tissue injury caused by torsion leads to compromise of the intestinal mucosa, favoring the inflammatory process and bacterial translocation, that is, favoring the migration of bacteria from the intestinal lumen to the circulation and even to the peritoneum, with the main complications being endotoxemia, Systemic Inflammatory Response Syndrome (SIRS) and sepsis. This study aims to conduct a survey of data from the literature on the effects of ischemia and intestinal reperfusion damage in the face of mesenteric root torsion in horses.
