“…The lesions found in this research are reported to be the most common form of disease observed at post-mortem inspection in cattle (Bica et al, 2018). In a similar study carried out by Ramos et al (2016), at the post-mortem inspection, lesions suggestive of tuberculosis were characterized by focal, multifocal or diffuse nodules, with a caseous appearance and a gritty cut surface in various organs and tissues.…”

Between November 2017 and August 2018, in order to determine the occurrence of tuberculosis in cattle slaughtered in the semi-arid region of Rio Grande do Norte, 11,610 bovine carcasses underwent a routine post-mortem inspection. One animal presented suggestive lesions and samples from lung, spleen and heart were submitted to microbiological culture in Stonebrink medium for 90 days and molecular analysis by nested-PCR. For histopathological examination and Ziehl Neelsen staining, the omentum was used. In the cultured samples, two of them (heart and spleen) showed growth, but were not confirmed as M. bovis by conventional PCR. At nested-PCR, the samples showed amplification for the TbD1 region. The presence of numerous granulomas was detected in the histopathological examination characterized by a necrotic center and areas of mineralization, as well as the presence of acid-fast bacilli (AFB) in the Ziehl-Neelsen stain. Microbiological culture can show false negative results, despite being considered a gold standard technique, although it takes time. Nested-PCR and histopathology show fast and effective results for the diagnosis of the disease. The presence of positive animals represents a public health risk in the studied region. Therefore, one of the essential systems applied to the control of bovine tuberculosis is the epidemiological surveillance of animals in slaughterhouses.

“…Hydatidosis, fasciolosis, and eosinophilic myositis by Sarcocystis species are parasitic diseases diagnosed at the slaughterhouse lines (Bica et al, 2018;Tessele et al, 2013a, b;Vangeel et al, 2013). These conditions may present as atypical lesions with exacerbate immune responses and/or involving unusual locations.…”

“…The diagnosis of fasciolosis, hydatidosis, and eosinophilic myositis caused by Sarcocystis species in this study was based on the gross and microscopic features of each condition. These parasitic diseases are commonly detected in cattle at the slaughterhouse lines in the Rio Grande do Sul state (Bica et al, 2018;Tessele et al, 2013a, b), as well as in other locations, in which hydatidosis stands out (Cardona & Carmena, 2013). Apart from being a health issue for consumers, these conditions cause economic losses for the cattle industry and producers (Cardona & Carmena, 2013;Costa et al, 2019).…”

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.
