Ocorrência de rota vírus e adeno vírus em crianças de até 11 anos de idade sem sintomatologia de diarréia em Goiânia - GO

Trezentas e oitenta e cinco amostras fecais provenientes de crianças na faixa etária de até 11 anos, sem sintomatologia de diarréia, foram estudadas objetivando-se a detecção de rotavirus. Desta amostragem, 268foram obtidas de crianças habitantes de creches e 117 de crianças atendidas no ambulatório do Hospital Lúcio Rebelo de Goiânia-Goiás. Todas as amostrasforam analisadas através da técnica de eletroforese em gel de poliacrilamida (EGPA- SDS), e 89 foram também analisadas pelo ensaio imunoenzimático adaptado para rotavirus e adenovirus (E1ARA). Rotavirus e adenovirus só foram detectados nas crianças atendidas no ambulatório, num percentual de 1,7% e 1,6% respectivamente, não havendo nenhuma positividade nas crianças de creches. Ambos os vírus ocorrerarh na faixa etária de 1 a 2 anos.<br>Three hundred and eigthy five children without a diagnosis of diarrhoeal illness had faecal specimens collected in order to detect rotavirus infection. The survey was conducted in Goiânia city - CentralBrazil and the children aged 0-11 years old were recruited (268 in day care centers and 117 from a local outpatient clinic - Hospital Lucio Rebelo). Detection of rotavirus was done by Polyacrylamide gel electrophoresis (PAGE - SDS), and 89 specimens were also analyzed by commercial enzyme immunoassays for rotavirus and adenovirus (EIARA). Rotaviruses and adenoviruses were only detected among the children attending the outpatient clinic. Prevalence rates of rotavirus and adenovirus excretion were of 1.7% and 1.6%, respectively. Both viruses were found among children from 1 to 2 years old

Growing knowledge: an overview of Seed Plant diversity in Brazil

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora
