“…As observações de macrocistos de Sarcocystis na musculatura (cardíaca ou diafragma) normalmente são causadas por S. hirsuta e S. hominis, porém S. cruzi é a espécie mais frequente na musculatura de bovinos, no Brasil e no mundo (Ghisleni et al, 2006;Mounika et al, 2018;Nourani et al, 2010;Nourollahi-Fard et al, 2015). Por serem intracelulares os sarcocistos de Sarcocystis estão protegidos das defesas imunes do hospedeiro, por esta razão na maioria dos casos não ocorre uma resposta inflamatória e o achado do protozoário em lâminas de músculo estriado é comum na rotina histopatológica (Tessele et al, 2013).…”

Resumo.A sarcocistose humana é adquirida pela ingestão de carne contaminada com cistos zoonóticos do protozoário Sarcocystis intramuscular, bovino ou suíno, envolvido no ciclo intestinal após o consumo de carne infectada. Esta pesquisa objetiva identificar cistos de Sarcocystis no músculo cardíaco de 146 bovinos abatidos em um frigorífico sob inspeção federal na cidade de Santa Cecília, no estado de Santa Catarina, Brasil. Corações foram selecionados e amostras da musculatura foram coletadas. Seções histológicas foram submetidas à microscopia para identificação dos cistos. Os sarcocistos basofílicos encistados entre as fibras musculares foram mensurados para determinar a espécie de acordo com critérios de forma e espessura da parede. De um total de 146 amostras de tecido cardíaco, nenhuma amostra evidenciou cistos macroscópicos e 86.6% (122) foram positivos para sarcocistos identificados pela espessura da parede (parede fina com menos de 1μm) como S. cruzi. A dificuldade de diagnosticar lesões macroscópicas deste parasito na inspeção de carne em abatedouros permite que este músculo seja comercializado.

“…The plasma sodium concentration is linked to the body's water balance, an increase in this electrolyte reflects the excess or deficit of water (hyponatremia or hypernatremia), making it necessary to ensure an adequate supply of sodium in the horse's diet and consumption of salt or electrolyte supplements (Tessele et al, 2013;Thomassian, 2005).…”

The physiological and biochemical responses of the equine athlete, before, during and after physical exercise, are studied in the exercise physiology and, for this to start and muscle contraction occurs, for this it is necessary that the organism produces energy through the production of ATP, which occur in three processes, being alactic or lactic, the alactic process occurs through the metabolism of creatine phosphokinase (anaerobic form) and glucose through the Krebs cycle (aerobic form), whereas the lactic process occurs through the metabolism of lactate. During exercise, in an attempt to re-establish equine parameters, physiological changes occur. The physiology of exercise has been studying, through stress tests, performed on an ergometric treadmill or in the field, ways of obtaining parameters to evaluate the species. This study aimed to evaluate an essential tool that is the physiology of exercise on the physical conditioning of equine athletes, through parameters that observe the performance of these animals. For the methodology, a bibliographic survey of articles was made and directed to the physiology of equine exercise, in addition, necessary tools for the evaluation of equine athletes were addressed, being these neurological, cardiovascular, skeletal, and electrolytic responses. It is concluded that the use of tests for the evaluation of the athletic performance in horses performed by treadmill or in the field together with the physiological responses obtained by the action of exercise and training, is considered a valuable tool for equine sports medicine.

“…Sarcocystis species, such as S. cruzi, S. hirsuta, and S. hominis, have been suggested to play a role in bovine eosinophilic myositis (Vangeel et al, 2013). Sarcocystis species are frequently observed as an incidental finding on the histologic exam, affecting the muscle fibers with greater blood supply, such as the heart, esophagus, and masseter muscle (Tessele et al, 2013b;Vangeel et al, 2013;Valentine & McGavin, 2012). Similarly, in the present study, lesions were observed in the skeletal and cardiac muscle.…”

In this study, we described the morphological features and unusual presentations of hydatidosis, fasciolosis, and eosinophilic myositis caused by Sarcocystis species diagnosed at the slaughterhouse lines. Twenty-seven samples of atypical parasitic lesions from distinct cattle were evaluated, of which 12 corresponded to hydatidosis, 11 to fasciolosis, and 4 to eosinophilic sarcocystosis. Hydatid cysts were observed mainly in the heart, with all cases involving the left ventricle. Fasciolosis lesions involved mainly the lungs, and were characterized by a focal nodular elevated area involving the edges of the lobes. Intralesional trematodes were observed in three cases. Sarcocystosis lesions were observed in four cases, and lesions were primarily located in the skeletal and cardiac muscles. Grossly, they presented as focal or focally extensive streaks, patches, or numerous nodules that were greenish to mildly yellowish. Histologically, all the cases had intralesional ruptured cysts of Sarcocystis that were associated with severe eosinophilic myositis and myocarditis. Parasitic lesions in atypical locations and/or with aberrant responses should be promptly identified because it may mistakenly diagnosed as other potentially zoonotic diseases, such as cysticercosis and tuberculosis.
