Atividade de extratos vegetais in vitro sobre ovos de nematóides gastrintestinais de ovinos.

Atualmente o uso indiscriminado de antiparasitários na ovinocultura se tornou rotina na maioria das propriedades e existe uma preocupação com relação aos resíduos dessas drogas nos produtos de origem animal e no ambiente. Além disto, a necessidade de se encontrar novos princípios ativos faz com que pesquisas com fitoterápicos se tornem cada vez mais freqüentes e assumam um caráter científico mais rigoroso. Esse estudo teve por objetivo avaliar a ação ovicida de extratos vegetais brutos sobre nematóides gastrintestinais de ovinos. Realizou-se testes in vitro por meio de metodologia padronizada de inibição de eclodibilidade. Foram avaliadas as seguintes espécies vegetais: extrato hidrometanólico das cascas do fruto (20 mg) e da semente (22 mg) de Trichilia elegans e partição metanólica das folhas de Euxylophora paraensis (20 mg). Os extratos foram produzidos no Departamento de Química da Universidade Federal de São Carlos e os testes foram realizados de acordo com a disponibilidade dos parasitas no Laboratório de Sanidade Animal da Embrapa Pecuária Sudeste (São Carlos, SP). Os ovos foram recuperados de fezes contaminadas por meio do uso seqüencial de peneiras e foram incubados (cerca de 100 ovos/poço) com os extratos em placas de 24 poços em B.O.D. a 25°C por 72 horas, quando foi realizada a contagem das larvas eclodidas. Os extratos tiveram seus solventes evaporados e depois testados a 100%, 50% e 25% da massa inicial, adicionando-se água destilada. Foram feitas três repetições e o controle contendo água destilada. Os extratos não apresentaram ação ovicida nas concentrações testadas, exceto o extrato hidrometanólico das cascas do fruto T. elegans a 100%. Enquanto no controle ocorreu eclodibilidade de 88,2% das larvas, neste tratamento a eclodibilidade foi de 21,5%, indicado a possibilidade de seu uso no controle desses parasitas

A case of feline gastrointestinal eosinophilic sclerosing fibroplasia associated with phycomycetes

Feline gastrointestinal eosinophilic sclerosing fibroplasia (FGESF) is a recently described inflammatory condition of domestic cats with unknown aetiology. A proportion of cases of FGESF are associated with bacteria, but antibiotic treatment is ineffective. It has been hypothesized that genetically predisposed cats may develop FGESF in response to the introduction of bacteria or other antigens into the intestinal wall. A 9- month-old male Persian cat presented with a history of marked acute haematemesis. A mass (10 cm diameter) was detected within the pylorus and proximal duodenum and this was not surgically accessible. On necropsy examination the duodenal wall was seen to be markedly thickened with extensive mucosal ulceration. Microscopically, there were haphazardly oriented trabecular bands of dense eosinophilic collagen,separated by wide, clear areas containing variable numbers of fibroblasts, eosinophils, mast cells, neutrophils,macrophages, lymphocytes and plasma cells. Numerous pleomorphic, non-parallel walled, sparsely septate hyphae, characteristic of phycomycetes, were present within the collagen matrix. Colonies of gram-positive and gram-negative rods were also present within the lesion. This is the first description of FGESF with intralesional fungi

Doc management: Proposal for a doctoral management system

Control is an essential function for good management, for which a bureaucratic organization, that is, a system of rules, regularized procedures, division of responsibilities, and hierarchy, contributes. This paper addresses the issues related to a problem encountered in the management of doctorate students. Traditionally manual, this process is no longer efficient. This brings problems such as difficulty in searching a student’s file and its information, difficulty in noticing if a student is undocumented, or in figuring out what tasks must be completed and turned in and what dates to do so. The current system is prone to delays, errors and requires unnecessary effort. The goal of this work was to develop a proposal to solve the problems described, by means of an application, with a simple interface, that can manage, create and edit students, their information, their grades and their deliveries, manage, create and edit curricular units and the related information, manage create and edit academic teachers and their functions. In other words, it is intended that the application is able to facilitate the management of all course processes and document a student's academic path. This will provide workers with a better quality of life, reducing the probability of error and generating gains in quality and efficiency in the management of student processes, thus improving the professional life of those who use the application.info:eu-repo/semantics/acceptedVersio

Six-year follow-up of slaughterhouse surveillance (2008-2013): the Catalan Slaughterhouse Support Network (SESC)

Meat inspection has the ultimate objective of declaring the meat and offal obtained from carcasses of slaughtered animals fit or unfit for human consumption. This safeguards the health of consumers by ensuring that the food coming from these establishments poses no risk to public health. Concomitantly, it contributes to animal disease surveillance. The Catalan Public Health Protection Agency (Generalitat de Catalunya) identified the need to provide its meat inspectors with a support structure to improve diagnostic capacity: the Slaughterhouse Support Network (SESC). The main goal of the SESC was to offer continuing education to meat inspectors to improve the diagnostic capacity for lesions observed in slaughterhouses. With this aim, a web-based application was designed that allowed meat inspectors to submit their inquiries, images of the lesions, and samples for laboratory analysis. This commentary reviews the cases from the first 6 years of SESC operation (2008–2013). The program not only provides continuing education to inspectors but also contributes to the collection of useful information on animal health and welfare. Therefore, SESC complements animal disease surveillance programs, such as those for tuberculosis, bovine cysticercosis, and porcine trichinellosis, and is a powerful tool for early detection of emerging animal diseases and zoonoses
