Resumo: |
Amongst the several parasite-diseases that may be found on the bovine species slaughter line, cysticercosis surely is the most frequent one. Besides being a zoonosis and a public health issue, it also causes great economic losses on the Brazilian meat productive chain. On the other hand, fasciolosis, also considered a zoonosis, has a lower occurrence when compared to cysticercosis, fact that may be due to its epidemiologic dynamics. Aiming to learn the level of infection of these zoonosis in the bovine herd of the state of Goiás, this project was undertaken with the scope of determining the prevalence and spatial distribution, as well to evaluate the association with some epidemiologic variables with the occurrence of these diseases and also to estimate economic losses inflicted on the producers and industries. A retrospective study was carried out on a total of 23.255.979 animals slaughtered per year, mesoregions and microregions. The data were used to create one epidemiologic map for bovine cysticercosis and one for bovine fasciolosis, gathering all cities of the state of Goiás. A prevalence of bovine cysticercosis on the state of Goiás of 0,53% (CI 95% 0,5295 – 0,5354), where the percentage of viable cysticercosis was 42,31%, non-viable cysticercosis 57,69% and the presence of bovine fasciolosis was de 0,0026% (CI 95% 0,0024 – 0,0028). The mesoregion Centro presented a greater chance (OR = 4,44) of finding positive cattle for cysticercosis when compared to the mesoregions Norte (OR = 1) and Nordeste (OR = 1,02), whilst the mesoregions diagnosed with greater chances of finding animals positive for fasciolosis, due to having a greater effective herd (p ≤ 0,05), were Noroeste, Sul, part of the region Centro and two cities of the region Leste of the state. The losses estimated for the evaluated period, from 2007 to 2014, ranged from R$ 64.809.817,50 (US$ 20.574.545,24) due to the presence of cysticercosis, and around R$ 15.072,75 (US$ 4.785) due to the presence of Fasciola hepatica in bovine liver. Such results outline the importance of developing strategic measures and action policies to try and control the spreading of these relevant zoonosis. |
