Cadeia produtiva da pecuária de corte do município de Tailândia, estado do Pará: estrutura e caracterização sanitária dos abates
(Universidade Federal do Pará, 2015) NORONHA, Gerlane Nunes; CASSEB, Alexandre do Rosário; http://lattes.cnpq.br/6525374874057337; PEREIRA, Washington Luiz Assunção; http://lattes.cnpq.br/9266281009742277; LOURENÇO JÚNIOR, José de Brito; http://lattes.cnpq.br/2919433679918544
This work aims to characterize the productive chain of beef cattle in the town of Tailândia, Pará, Mesoregion Northeast Pará, in order to identify the state of the art and emphasize the slaughter stage and prevalence of economic losses carcasses of convictions and cattle organs and confirmation by microbiological analysis of lesions suggestive of bovine tuberculosis. For evaluations, secondary data on government and institutional sites, primary data through interviews with producers, cold slaughterhouse owner, community leaders and experts from public entities were used. In second phase, primary data through spreadsheets slaughtering records and convictions of carcasses and viscera were evaluated, from March 2010 to October 2014 and found that bovine tuberculosis was one of the highest conviction pathologies (2.98%) and generating greater economic loss (71.48%). Given these results, we sought confirmation by histopathological analysis and polymerase chain reaction - PCR in order to characterize the lesions and identify the presence of Mycobacterium bovis. The histopathology showed that only 1.96% of the samples corresponded to the inflammatory process characteristic of tuberculosis and 4.25% with amplification profile for the species of M. bovis. The results of this study allow us to conclude that there is need to use complementary methods to improve diagnostic of bovine tuberculosis in slaughterhouses to increase the epidemiological disease control, streamline the inspection service and reduce economic losses generated, which will make the strongest production chain.

Fauna microparasitária de Brachyplatystoma rousseauxii e Mugil curema desembarcados na Amazônia oriental
(Universidade Federal do Pará, 2013-11-29) DIAS, Lilian de Nazaré Santos; MATOS, Edilson Rodrigues; http://lattes.cnpq.br/7895814591867510; PAIVA, Rosildo Santos; http://lattes.cnpq.br/0510818763187669; FREITAS, José de Arimatéa; http://lattes.cnpq.br/2382745365421156
The gilthead bream Brachyplatystoma rousseauxii and white mullet Mugil curema are species of fish consumption and considerable commercial value found in estuarine cost of Pará The microparasites phyla Apicomplexa, Microspora and Myxozoa are organisms that can be found parasitizing vertebrates and invertebrates, including the fish, some pathogenic potential and even zoonotic and economic impact. To discover the fauna microparasites affecting fish , 62 specimens of B. rousseauxii and 58 M. curema estuarna captured on the coast of the city of Vigia de Nazare and Mosqueiro District, in Belem, Para state were examined as methods and techniques for morphological analysis (microscopy light), ultrastructural (transmission electron microscopy, TEM) and molecular biology (phylogenetic analysis). It was observed that there are three phyla (three in B. rousseauxii and two in M. curema) captured hosts in the two locations , plus the largest parasitic index was determined in specimens of both captured on the coast of the estuarine Vigia de Nazare , higher incidence of co microparasites phyla Apicomplexa and Myxozoa, beyond multiparasitism in B. rousseauxii Morphological analysis revealed the presence of Calyptospora sp. (Apicomplexa), Ellipsomyxa sp., Henneguya sp., Myxobolus sp. and Meglishcha sp. (Myxozoa) and Kabatana sp. (Microspora) in B. rousseauxii and Ellipsomyxa sp., Myxobolus sp. and Microspora phylum microparasito in M. curema. The data analysis of morphological and ultrastructural Myxospora found in B. rousseauxii and M. curema are suggestive of new species microparasites these two hosts. Phylogenetic analysis of the data did not provide results that allow the classification of Kabatana sp. (Microspora) and Henneguya sp. (Myxozoa) found parasitizing B. rousseauxii microparasites as new species in this host due to low bootstrap value, but by analyzing the distance p was possible to suggest that these are new species. Studies about microparasites in Amazonian fish are needed for the knowledge of the occurrences, characterization d new species, the pathogenic potential hosts and possible risk to the consumer.
