Clustering Of Water Bodies In Unpolluted And Polluted Environments Based On Escherichia Coli Phylogroup Abundance Using A Simple Interaction Database.

Different types of water bodies, including lakes, streams, and coastal marine waters, are often susceptible to fecal contamination from a range of point and nonpoint sources, and have been evaluated using fecal indicator microorganisms. The most commonly used fecal indicator is Escherichia coli, but traditional cultivation methods do not allow discrimination of the source of pollution. The use of triplex PCR offers an approach that is fast and inexpensive, and here enabled the identification of phylogroups. The phylogenetic distribution of E. coli subgroups isolated from water samples revealed higher frequencies of subgroups A1 and B23 in rivers impacted by human pollution sources, while subgroups D1 and D2 were associated with pristine sites, and subgroup B1 with domesticated animal sources, suggesting their use as a first screening for pollution source identification. A simple classification is also proposed based on phylogenetic subgroup distribution using the w-clique metric, enabling differentiation of polluted and unpolluted sites.

Fish Biodiversity Of The Vitória-trindade Seamount Chain, Southwestern Atlantic: An Updated Database.

Despite a strong increase in research on seamounts and oceanic islands ecology and biogeography, many basic aspects of their biodiversity are still unknown. In the southwestern Atlantic, the Vitória-Trindade Seamount Chain (VTC) extends ca. 1,200 km offshore the Brazilian continental shelf, from the Vitória seamount to the oceanic islands of Trindade and Martin Vaz. For a long time, most of the biological information available regarded its islands. Our study presents and analyzes an extensive database on the VTC fish biodiversity, built on data compiled from literature and recent scientific expeditions that assessed both shallow to mesophotic environments. A total of 273 species were recorded, 211 of which occur on seamounts and 173 at the islands. New records for seamounts or islands include 191 reef fish species and 64 depth range extensions. The structure of fish assemblages was similar between islands and seamounts, not differing in species geographic distribution, trophic composition, or spawning strategies. Main differences were related to endemism, higher at the islands, and to the number of endangered species, higher at the seamounts. Since unregulated fishing activities are common in the region, and mining activities are expected to drastically increase in the near future (carbonates on seamount summits and metals on slopes), this unique biodiversity needs urgent attention and management.

Formação de profissionais de saúde no Brasil: uma análise no período de 1991 a 2008

Estudo conduzido com o objetivo de contribuir para o planejamento e implementação de políticas de qualificação profissional no campo da saúde. Foram analisados 14 cursos de graduação da área da saúde: biomedicina, ciências biológicas, educação física, enfermagem, farmácia, fisioterapia, fonoaudiologia, medicina, medicina veterinária, nutrição, odontologia, psicologia, serviço social e terapia ocupacional, no período de 1991 a 2008. Dados sobre número de ingressantes, taxa de ocupação de vagas, distribuição de concluintes por habitante, gênero e renda familiar foram coletados a partir dos bancos do Ministério da Educação. Para o curso de medicina, a relação foi de 40 candidatos por vaga nas instituições públicas contra 10 nas privadas. A maioria dos ingressantes era composta por mulheres. A região Sudeste concentrou 57% dos concluintes, corroborando o desequilíbrio de distribuição regional das oportunidades de formação de profissionais de saúde e indicando a necessidade de políticas de incentivo à redução dessas desigualdades.

First record of Stygnidae for the state of Espírito Santo and description of a new Protimesius (Arachnida: Opiliones: Laniatores)

Protimesius osvaldoi sp. nov. is described from the Reserva Biológica de Sooretama, state of Espírito Santo, southeastern Brazil, being the first record of Stygnidae from this State and the southernmost record of the family in the Brazilian Atlantic Forest (hitherto, the family was recorded down to Bahia only), extending in 210 km south of the previously known distribution. This is a large species, with armature of leg IV very reduced and penial morphology differing from the closest counterparts mainly in the ventral plate, which recedes deeply at the lateral borders and has the distal margin curved ventrally and by the presence of two small intermediate setae. Protimesius Roewer, 1913 consisted hitherto of 17 species, recorded from northern/northeastern Brazil and Amazonia of adjacent countries. A key is given for the 17 species of Protimesius for which males are known.

Second record of bioluminescence in larvae of Xantholinus Dejean (Staphylinidae, Xantholinini) from Brazil

Second record of bioluminescence in larvae of Xantholinus Dejean, (Staphylinidae, Xantholinini) from Brazil. Bioluminescent Xantholinus larvae (Xantholinini, Staphylinidae) were collected in the Cerrado biome of Mato Grosso state, Brazil. These larvae are morphologically similar to the first bioluminescent larvae of this genus collected in the Atlantic Forest in São Paulo state; however they differ by their bioluminescent emission.

First Record of Culex (Culex) brethesi (Dyar) (Diptera: Culicidae) in Rio Grande do Sul State, Brazil

This is the first record of Culex (Culex) brethesi (Dyar) in Rio Grande do Sul state, Brazil. The species was identified from specimens collected in a sand bar vegetation with the aid of a Nasci's trap, during an expedition for surveillance of the West Nile Virus in July of 2006, in the city of Mostardas, Rio Grande do Sul, Brazil.

Vinculação determinística de Bancos de Dados sobre mortalidade por Aids

A vinculação determinística de bancos de dados sobre mortalidade por aids tem apresentado problemas causados por falhas nos arquivos. Assim, os objetivos deste estudo foram: avaliar o desempenho da vinculação determinística em bancos de óbito por aids do Programa de Aprimoramento das Informações de Mortalidade no Município de São Paulo (PRO-AIM) e da Fundação SEADE entre os anos de 2000 e 2004 e estimar a cobertura de cada banco. Utilizou-se a rotina merge de um software para vincular os bancos. A primeira etapa pareou os registros automaticamente e, na segunda etapa, cada banco foi conferido para localizar novos pares. Estimaram-se os óbitos pela soma entre casos pareados e não pareados para calcular a cobertura dos bancos. A primeira etapa da vinculação identificou 91,6% dos pares. A segunda etapa adicionou 457 pares. O total de óbitos foi estimado em 5.855, com cobertura de 97,1% do PRO-AIM e 96% do SEADE. O uso da vinculação determinística cobriu grande parte dos casos. O banco do PRO-AIM proporcionou a maior cobertura, com maior quantidade de informações completas e melhor localização geográfica dos casos.

Atenção farmacêutica em farmácias e drogarias: existe um processo de mudança?

Para se conhecer a prática profissional de farmacêuticos que atuam em farmácias e drogarias, seus conhecimentos e percepções acerca da Atenção Farmacêutica (AF), realizou-se estudo descritivo com 91 farmacêuticos do município de Jundiaí-SP. A maioria era jovem (62,6% entre 20 e 29 anos), do sexo feminino (63,7%), graduada em instituições privadas (90,1%) e não proprietária do estabelecimento (87,9%). Desenvolviam atividades administrativas, técnicas e de atenção ao usuário, principalmente dispensação de medicamentos e orientação; 67,0% acompanhavam o tratamento farmacoterapêutico dos usuários, mas sem registrar informações. Para 62,7%, AF relacionava-se apenas à orientação e atendimento dispensados, mas tais atividades não eram realizadas de forma sistemática e organizada, como preconizado. Muitos (91,2%) consideravam necessário realizar trabalho mais intenso com os usuários, porém apontaram dificuldades como falta de tempo e de apoio dos proprietários e desinteresse dos usuários. Várias dessas dificuldades têm sido verificadas também em outros países, sugerindo que a prática da AF: (a) requer uma mudança estrutural e rearranjo de funções, uma vez que, atualmente, a estrutura e as atividades são adequadas à atividade comercial; (b) reflete uma crise de identidade profissional e, em consequência, falta de reconhecimento social e pouca inserção na equipe multiprofissional de saúde. O conhecimento sobre AF mostrou-se limitado, mas a situação pode vir a alterar-se à medida que as mudanças curriculares em curso surtam efeito na formação dos novos farmacêuticos.

Resurrection of Anopheles goeldii from synonymy with Anopheles nuneztovari (Diptera, Culicidae) and a new record for Anopheles dunhami in the Brazilian Amazon

Nucleotide sequences of the internal transcribed spacer 2 (ITS2) rDNA and partial sequences of the cytochrome coxidase subunit I (COI) mtDNA and white gene nDNA were obtained from specimens of Anopheles nuneztovari A collected in Macapá (state of Amapá), Óbidos, Prainha and Almeirim (state of Pará), Itacoatiara and Parintins (state of Amazonas), Brazil, and compared with previously published sequences of A. nuneztovari s.l. Results of the Bayesian phylogenetic analyses performed using either COI or combined ITS2, COI and white gene sequences suggest that An. nuneztovari B/C is distinct from specimens obtained in the Amazonas/Solimões River basin. Anopheles goeldii, currently in synonymy with An. nuneztovari, was described from individuals collected in Belterra (= Fordlândia) in the Tapajós River, state of Pará, Southern Amazonas River. Morphological comparisons of the characteristics of the male genitalia indicated that An. nuneztovari A and An. goeldii are similar but distinct from An. nuneztovariB/C by the apex of the aedeagus. In considering the results of the phylogenetic analyses and morphological comparisons, An. goeldii is resurrected from synonymy with An. nuneztovari. Additionally, Anopheles dunhamiis reported for the first time in Parintins. This species can be distinguished from An. goeldiiby characters of the male genitalia and molecular data

The first record on Brazilian stingless bees published 450 years ago by Hans Staden

Only a few decades after 1492, when Christopher Columbus arrived on a Caribbean island and Pedro Alvares Cabral claimed Brazil for Portugal in 1500, a German mercenary gave the first description of stingless bees in 1557. He got to know them when he was imprisoned for months by an anthropophagous tribe in the coastal region of Santos, today in the State of Sao Paulo. This rather short but nevertheless extremely exact record on stingless bees is hidden in the first book on Brazil. Three species and important aspects of their life history were treated. This early description has been completely overlooked by bee scientists until now. My note intends to close this evident gap.

Spiranthera atlantica (Rutaceae, Galipeae), a New Species and the First Record of the Genus for the Brazilian Atlantic Forest

A new species of Spiranthera A. St.-Hil. (Rutaceae, Galipeinae) is illustrated and described from Espirito Santo, Brazil. Spiranthera atlantica Pi rani represents the first species record for the genus in the Atlantic Forest of eastern Brazil. The new (axon resembles the Amazonian S. guianensis Sandwith but differs by its smaller, few-flowered inflorescences and by the fruit and leaflet morphology.

FORAMINIFERAL RECORD OF CHANGES IN SUMMER MONSOON PRECIPITATION AT THE SOUTHEASTERN BRAZILIAN CONTINENTAL MARGIN SINCE THE LAST GLACIAL MAXIMUM

Changes in the oxygen isotopic composition of the planktonic foraminifer Globigerinoides ruber and in the foraminifera faunal composition in a core retrieved from the southeastern Brazilian continental margin were used to infer past changes in the hydrological balance and monsoon precipitation in the western South Atlantic since the Last Glacial Maximum (LGM). The results suggest a first-order orbital (precessional) control on the South American Monsoon precipitation. This agrees with previous studies based on continental proxies except for LGM estimates provided by pollen records. The causes for this disagreement are discussed.
