The distribution of Neospora caninum, an important agent of reproductive disorders in cattle, has been frequently reported in dairy cattle in Brazil and worldwide. Records of infection are less frequent in beef cattle. To determine the seroprevalence of bovine neosporosis, 507 beef cattle blood samples were collected from

Fasciola hepatica is reported as a trematode of great importance, causing fasciolosis, one of the most neglected zoonotic parasitic diseases in the world. In Brazil, potential losses of around US$ 210 million per year were calculated, with bovine fasciolosis alone. The State of Santa Catarina is located in the South Region of Brazil, with a herd of more than 4 million ruminants. The Serrana Mesoregion, historically free of fasciolosis, is composed of 30 municipalities, which have a consolidated agricultural tradition, mainly in extensive ruminant livestock. The objective of the present work was to investigate the occurrence and distribution of autochthonous cases of bovine fasciolosis in the region. For this, different analyzes were carried out in rural properties from eight municipalities, and in three slaughterhouses under the State Inspection Service (SIE), which received animals from all the Serrana Mesoregion. The rural properties were randomly selected, and up to 20 fecal samples were collected from random cattle older than 1 year, for analysis by coproparasitological sedimentation test. The traceability records of the positives were checked, for identifying autochthonous cases. Additionally, the tracking data of cattle slaughtered between the years of 2018 and 2021, which presented liver condemnations, were analyzed for defining autochthonous cases of bovine fasciolosis. In total, there were fecal samplings in 106 farms, with 1,927 tested cattle. From these, 178 (9.2%) were positive and autochthonous, but the overall result did not reflect the heterogeneity found between the evaluated municipalities. During the analyzed period, 11,556 cattle were slaughtered, with 1,744 (15.1%) liver condemnations due to fasciolosis in animals that never left the Serrana Mesoregion. The present study confirmed the presence of autochthonous cases of bovine fasciolosis in municipalities of the Serrana Mesoregion, and verified a high rate of positivity in animals slaughtered in the regional slaughterhouses. When the prevalence of bovine fasciolosis in vivo was compared with the postmortem positivity index in five municipalities, the results disagreed in four municipalities (p-value < 0.05), emphasizing the need for field investigation for the better understanding of the distribution and frequency of the parasitosis.

Bovine cysticercosis disease is prevalent worldwide, and is diagnosed frequently in slaughterhouses. This disease has an impact on animal production and public health due to Taenia saginata. In order to investigate the occurrence of bovine cysticercosis in the mountainous region of Santa Catarina state, Brazil, we performed a retrospective survey of beef carcasses that were positive for the parasite. We tabulated and analyzed the records of cattle that were slaughtered from 2003 to 2013, under the state inspection in Lages, Santa Catarina. These records were provided by Companhia Integrada de Desenvolvimento Agrícola de Santa Catarina (CIDASC). The data were analyzed using Chi-square test (P ≤ 0.05) to correlate the cysticerci occurrence with the independent variables. The animals were from the 18 municipalities that represent Associação dos Municípios da Região Serrana (AMURES). Among the animals that were slaughtered during the study period, 7.06% (1698/24055) were confirmed positive for cysticercosis during the visual inspection. Among the total cysts that were inspected, 25.79% and 74.20% were classified as viable and calcified, respectively. The most frequently parasitized organs were the head, with 876 cases (51.59%) positive for cysticerci (321 [36.64%] . In addition to the generalized infection (4.48%), the tongue and the diaphragm were the next most commonly parasitized organs, with 3.71% and 2.47% cases positive for cysticerci, respectively. There was no correlation (P > 0.05) between sex or age, and positive infection or cyst location. We identified statistical variations among the results for each of the evaluated years (P < 0.01). These reports indicated a significant increase in the infection rate over time, from 4.58% (2005) to 9.94% (2013). We analyzed the correlation (P < 0.01) between the occurrence of cysticercosis and the origin of the animals as well as between the viability of cysts and their location in the body. These results suggest that the occurrence of bovine cysticercosis in the mountainous region of Santa Catarina is high and at an alarming rate. Bovine cysticercosis can lead to an economic loss and can endanger public health. Therefore, government agencies need to plan and implement measures in order to control this disease. 36%)], e coração com 641 notificações (37,75%) [sendo 54 cisticercos viáveis (8,42%) e 587 inviáveis (91,58%)], seguidos de localização generalizada, língua e diafragma com 4,48%, 3,71% e 2,47%, respectivamente. Não foi observada correlação (P > 0,05) entre sexo ou idade com a positividade e a localização dos cistos. Diferença estatística foi observada entre anos avaliados (P < 0,01), tendo a ocorrência variado de 4,58% (2005) a 9,94% (2013), indicando um aumento dos registros ao longo do tempo. Foi verificada correlação (P < 0,01) entre a ocorrência de cisticercose e a procedência dos animais assim como entre a viabilidade dos cistos e sua localização. A ocorrência da cisticercose bovina na região serrana de Santa Catarina é alta e alarmante, que po...
