Campilobacteriose em bovinos de carne no Alentejo – avaliação preliminar

The aim of this study was to assess the prevalence of infection by Campylobacter fetus in beef cattle reared in extensive systems in Alentejo region by direct fluorescent antibody test (DFAT), a technique widely used for determining the prevalence of this disease.

An Assessment to Toxicological Risk of Pesticide Exposure

On the one hand, pesticides may be absorbed into the body orally, dermally, ocularly and by inhalation and the human exposure may be dietary, recreational and/or occupational where toxicity could be acute or chronic. On the other hand, the environmental fate and toxicity of the pesticide is contingent on the physico-chemical characteristics of pesticide, the soil composition and adsorption. Human toxicity is also dependent on the exposure time and individual’s susceptibility. Therefore, this work will focus on the development of an Artificial Intelligence based diagnosis support system to assess the pesticide toxicological risk to humanoid, built under a formal framework based on Logic Programming to knowledge representation and reasoning, complemented with an approach to computing grounded on Artificial Neural Networks. The proposed solution is unique in itself, once it caters for the explicit treatment of incomplete, unknown, or even self-contradictory information, either in terms of a qualitative or quantitative setting.

Clínica e cirurgia de pequenos animais

Este relatório foi elaborado na sequencia do estágio curricular realizado pelo autor, ente 28 de setembro de 2015 e 28 de março de 2016, no Hospital Clínico Veterinario de la Universidad CEU Cardenal Herrera (HCV CEU-UCH), em Alfara del Patriarca, Valência, Espanha. A infeciologia foi a área da clínica médica mais representativa (28%), sendo o vírus da imunodeficiência felina (FIV) o agente infecioso registado mais frequentemente (19%). É importante reconhecer e diagnosticar esta infeção de forma a aplicar um maneio adequado aos pacientes infetados, melhorando a sua qualidade de vida e prevenindo a propagação do vírus. A infeção provocada pelo FIV raramente provoca uma síndrome severa, porém, várias alterações podem decorrer. Apesar do FIV provocar uma infeção crónica, com os cuidados adequados, os pacientes infetados poderão viver vidas longas, com uma boa qualidade de vida, e eventualmente acabar por morrer de causas não relacionadas com o FIV; Abstract: Small Animal Medicine and Surgery This report was elaborated following the externship performed by the author, between September 28th 2015 and March 28th 2016, at the Hospital Clínico Veterinario de la Universidad CEU Cardenal Herrera (HCV CEU-UCH), in Alfara del Patriarca, Valencia, Spain. The most frequent specialty field within the area of internal medicine was infectiology (28%), with feline immunodeficiency virus (FIV) being the infectious agent most frequently registered (19%). It is important to recognize and diagnose the infection caused by this agent accurately, so that the right measures of management can be applied, improving the life’s quality of the patient and reducing the risk of viral spreading. The infection by FIV rarely produces a severe syndrome, however many clinicopathologic disorders may occur. FIV causes a chronic infection, however, with the proper care, the infected cats may live long lives, with a fair quality, eventually ending up dying from causes unrelated to FIV.
