Serological detection of antibodies against Paracoccidioides brasiliensis in dogs with leishmaniasis

The aim of this study was to detect antibodies against Paracoccidioides brasiliensis in dogs seropositive and seronegative for leishmaniasis. Sera from 836 dogs (449 positive and 387 negative to leishmaniasis) were analysed by ELISA and the immunodiffusion test using gp43 and exoantigen, respectively. The analysis of the 836 serum samples by ELISA and the immunodiffusion test showed a positivity of 67.8 % and 7.3%, respectively, for P. brasiliensis infection. The dogs positive to leishmaniasis showed a higher reactivity to gp43 (79.9%) and exoantigen (12.7%) than the negative ones (54.0% and 1.0%, respectively). The higher reactivity to P. brasiliensis antigens may be due to cross-reactivity or a co-infection of dogs by Leishmania and P. brasiliensis. The lower correlation (0.187) observed between reactivity to gp43 and Leishmania antigen reinforces the latter hypothesis

Um cenário de possibilidades para o estágio curricular supervisionado no contexto de um instituto federal

Este artigo trata da pesquisa acerca da formação inicial de professores, focando o Estágio Curricular Supervisionado (ECS). O objetivo foi investigar o processo de estágio e buscar novas alternativas de atuação do docente recém-formado pelo viés da pesquisa. Neste texto, apresenta-se um recorte da pesquisa, que trata do atual modelo de prática do ECS e apresenta uma proposta de alteração pelo viés da pesquisa. Para tanto, utilizou-se, como metodologia, a análise de documentos, de fontes escritas e orais, além da observação in loco nas escolas em que os estudantes realizaram os estágios. Participaram quatro professores orientadores de estágio e quatro estagiários. Os resultados revelam que o estágio vem sendo realizado numa concepção de racionalidade técnica e, para a sua superação, é preciso que seja tratado como elemento articulador que perpassa as diferentes disciplinas que compõem a matriz curricular, e que ocorram reflexões coletivas para estudo, planejamento, execução e avaliação das ações.Este artículo trata de la investigación acerca de la formación inicial de maestros, enfocada en la Pasantía Curricular Supervisada (PCS). El objetivo fue investigar el proceso de pasantía y buscar nuevas alternativas de actuación del docente recién graduado por la tendencia de la investigación. En este texto, se presenta un recorte de investigación que trata del modelo actual de práctica de la PCS y presenta una propuesta de alteración por la tendencia de la investigación. Para tanto, se ha utilizado como metodología el análisis de documentos, fuentes escritas y orales, además de la observación in loco en las escuelas en las que los estudiantes realizaron sus pasantías. Participaron cuatro profesores orientadores de pasantía y cuatro pasantes. Los resultados revelan que la pasantía es realizada en una concepción de racionalidad técnica y, para su superación, es necesario que sea tratada como un elemento articulador que permea las diferentes asignaturas que componen la matriz curricular, y que ocurran reflexiones colectivas para estudio, planeamiento, ejecución y evaluación de las acciones.This article reports of the research about the initial formation of teachers, focusing on the Supervised Curricular Internship (SCI). The main goal was to investigate the internship process and search for new alternatives of action for the recently graduated teacher. In this paper, we present a framed research about the current SCI model and proposes an alteration through research bias. For this purpose, we accessed action research methodology, analyzing written documents, oral sources and on-site observation in schools where teaching students perform internships. Four teachers and four interns took part on the research. The results show that the internship has taken place in a technical rationality conception. For its overcoming, internship has to be treated as an articulating element that crosses the different disciplines that are part of the curricular matrix. It’s also necessary that collective reflections are made about study, planning, implementation and evaluation of actions.Apoio financeiro do CIEC (Centro de Investigação em Estudos da Criança, IE, UMinho; UI 317 da FCT, Portugal) através do Projeto Estratégico UID/CED/00317/2013, financiado através dos Fundos Nacionais da FCT (Fundação para a Ciência e a Tecnologia), cofinanciado pelo Fundo Europeu de Desenvolvimento Regional (FEDER) através do COMPETE 2020 – Programa Operacional Competitividade e Internacionalização (POCI) com a referência POCI-01-0145-FEDER-007562info:eu-repo/semantics/publishedVersio

Epidemiology of Invasive Fungal Infections in Latin America

The pathogenic role of invasive fungal infections (IFIs) has increased during the past two decades in Latin America and worldwide, and the number of patients at risk has risen dramatically. Working habits and leisure activities have also been a focus of attention by public health officials, as endemic mycoses have provoked a number of outbreaks. An extensive search of medical literature from Latin America suggests that the incidence of IFIs from both endemic and opportunistic fungi has increased. The increase in endemic mycoses is probably related to population changes (migration, tourism, and increased population growth), whereas the increase in opportunistic mycoses may be associated with the greater number of people at risk. In both cases, the early and appropriate use of diagnostic procedures has improved diagnosis and outcome
