Scientific determination and wood anatomical features of species know in Brazilian Amazonia as matá-matá (Eschweilera spp.).
Despite the large diversity, logging on Brazilian Amazon is restricted to a small number of species. On relating the local biodiversity to the density, region of occurrence and logging of traditional species, we verified the increment of their shortage. One way to minimize this problem is by introducing new species in the market. Based on these considerations, we sought to identify in the field, woods known as matá-matá (Eschweilera Mart. Ex DC. ? Lecythidaceae) of high frequency in the Brazilian Amazon. For this, eleven trees were collected for scientific identification, and for anatomical, physical and chemical analyses. During the identification, we verified the presence of six species (Eschweilera amazonica, Eschweilera coriacea, Eschweilera grandiflora, Eschweilera idatimon, Eschweilera ovata and Eschweilera sp.) which may be identified in the forest by their rytidomes and live bark characteristics. By organoleptic properties, we grouped the woods into three groups with distinct colours, which permitted the identification of two species by their characteristics of taste and smell. Macroscopically, all woods seemed similar, while microscopically, the species presented few differences which made their partial separation possible
Energetic characterization of Matá-Matá wood from the brazilian rainforest (Eschweilera Mart Ex Dc).
Apesar da grande diversidade da Floresta Amazônica, apenas um número restrito de espécies arbóreas é explorado, resultando em um aproveitamento parcial das áreas florestais em exploração, com conseqüências técnicas, econômicas e ambientais desvantajosas. Muitas espécies de grande freqüência na Amazônia brasileira, aptas ao manejo florestal, algumas vezes não são comercializadas por desconhecimento de suas propriedades, entre estas, cita-se o gênero Eschweilera Mart. Ex DC. ? Lecythidaceae, popularmente conhecido como matá-matá. Tendo isto em vista, o presente trabalho objetivou caracterizar física e quimicamente, e avaliar o potencial energético da madeira de Eschweilera. Para tanto, determinou-se os teores dos principais componentes químicos, poder calorífico superior (PCS), densidade básica (DB) e a densidade energética (DE) da madeira de 11 indivíduos de matá-matá. Os resultados observados foram comparados com os obtidos a partir de um clone de Eucalyptus comumente utilizado como fonte energética. As madeiras de Eschweilera sp., comparativamente ao Eucalyptus, apresentaram maiores valores de DB, DE, teor em lignina e minerais. A madeira de matá-matá apresenta características químicas e física superiores às espécies comumente utilizadas como fonte de energia
Rapid diagnosis of coccidioidomycosis by nested PCR assay of sputum
Coccidioidomycosis is a deep infection caused by two dimorphic fungi, Coccidioides immitis and Coccidioides posadasii. Diagnosis of the disease requires culture of suspicious clinical samples on mycological media. However, as these species are virulent pathogens, handling of their cultures is a high-risk activity, and is limited to Biosafety Level 3 laboratories. This study describes the direct detection of C. posadasii DNA in an inappropriate sputum sample by PCR amplification of the highly specific Ag2/PRA antigen gene. the results obtained suggest that direct detection of the Ag2/PRA sequence in sputum is an excellent method for rapid and specific diagnosis of coccidioidomycosis.Fed Univ Ceara, Med Mycol Specialized Ctr, Fortaleza, Ceara, BrazilFed Univ Ceara, Postgrad Program Med Sci, Fortaleza, Ceara, BrazilState Univ Ceara, Postgrad Program Vet Sci, Fortaleza, Ceara, BrazilState Univ Ceara, Dept Sci Biol, Fortaleza, Ceara, BrazilUniversidade Federal de São Paulo, Dept Microbiol Immunol & Parasitol, São Paulo, BrazilUniversidade Federal de São Paulo, Dept Microbiol Immunol & Parasitol, São Paulo, BrazilWeb of Scienc
Equine infectious anaemia in equids of Southern Pantanal, Brazil: seroprevalence and evaluation of the adoption of a control programme.
The working equid population in Corumbá, Southern Pantanal, is very large and has a crucial role in the main economic activity of the State of Mato Grosso do Sul, the beef cattle industry. The aim of the present study was to estimate the prevalence of equine infectious anaemia (EIA) in working equids of ranches in the municipality of Corumbá, by the official agar gel immunodiffusion (AGID) test, and evaluate the adoption of the Programme for the Prevention and Control of Equine Infectious Anaemia proposed by Embrapa Pantanal and official entities in the 1990s. From September to November 2009, forty ranches distributed through the area of the municipality were visited, and serum samples were obtained from 721 equines and 232 mules. According to previous publications and the present data, it was concluded that the prevalence of EIA in this population has increased from 18.17% to 38.60%, which represents at this time approximately 13,000 infected animals. There was no significant difference between the apparent prevalence of equines and mules. It was also verified that the control programme was not known by the greater part of the interviewed ranch owners, managers and foremen and, in their perception, EIA is not a primary threat to address. Among the studied variables, the serologic testing practice significantly reduced the risk for the presence of EIA seropositivity, as well as the separation of riding equipment and segregation of seropositives.Título em português: Anemia infecciosa equina em equídeos do Pantanal Sul, Brasil: soroprevalência e avaliação da adoção de um programa de controle
Measles outbreak after 12 years without endemic transmission, Portugal, February to May 2017
We report a measles outbreak in two Portuguese health regions (Algarve and Lisbon and the Tagus Valley) since February 2017, and which by 31 May resulted in 28 confirmed cases, of which 16 were unvaccinated. Thirteen cases were healthcare workers. One unvaccinated teenager died. Genotype B3 was identified in 14 cases from both regions. This outbreak occurs after 12 years without endemic measles transmission, and in a context of high measles vaccination coverage and immunity.info:eu-repo/semantics/publishedVersio
