Book excerpt: Este estudo visou analisar a qualidade microbiológica do leite humano cru recebido em um banco de leite humano (BLH), quantificando os microrganismos aeróbios mesófilos, Staphylococcus coagulase positivos (ECP), coliformes totais e Escherichia coli. Foram realizadas análises microbiológicas em 60 amostras de leite humano cru recebidas no BLH e os resultados foram os seguintes: o microrganismo E. coli foi positivo em 50% das amostras analisadas, os coliformes totais em 75% delas, o ECP em 46,66% e em 96,66% do total das amostras foram detectados microrganismos aeróbios mesófilos. Das amostras analisadas, a população de E. coli foi positiva em 93,33% (28 amostras) com uma variação entre 1 e 99 NMP/mL; 3,33% (1 amostra) entre 104 e 9,9 x 104 NMP/mL; 3,33% (1 amostra) entre 105 e 9,9 x105 NMP/mL. A população de coliformes totais que foi positiva em 57,77% (26 amostras) das amostras analisadas ficou entre 1 e 99 NMP/mL; 24,4% (11 amostras) ficaram entre 102 e 9,9x102 NMP/mL; 2,22% (1 amostra) entre 103 e 9,9x103 NMP/mL; 8,88% (4 amostras) entre 104 e 9,9x104 NMP/mL; 4,44% (2 amostras) entre 105 e 9,9x105 NMP/mL; 2,22% (1 amostra) entre 106 e 9,9x106 NMP/mL. Os microrganismos aeróbios mesófilos apresentaram-se na quase totalidade das amostras, sendo que 17,24% (10 amostras) variaram de 1 a 99 UFC/mL; 17,24% (10 amostras) entre 102 e 9,9x102 UFC/mL; 10,34% (6 amostras) ficaram entre 103 e 9,9 x 103 UFC/mL; 25,86% (15 amostras) entre 104 e 9,9 x104 UFC/mL; 17,24% (10 amostras) entre 105 e 9,9 x 105 UFC/mL; 10,34% (6 amostras) entre 106 e 9,9x106 UFC/mL e 1,72% (1 amostra) entre 107 e 9,9x107 UFC/mL. Porém, 3,33% (2 amostras) apresentaram-se negativas. Do total de amostras analisadas, o grupo dos microrganismos ECP apresentouse em 78,57% (22 amostras) com variação entre 1 e 99 UFC/mL; em 3,57% (1 amostra) entre 102 e 9,9x102 UFC/mL; 10,71% (3 amostras) entre 103 e 9,9x103 UFC/mL e 7,14% (2 amostras) entre 104 e 9,9 x 104 UFC/mL.

Book excerpt: O presente trabalho teve como objetivo geral o levantamento de aspectos relacionados com a qualidade do leite humano ordenhado e manuseado nos Bancos de Leite. O experimento foi desenvolvido em quatro fases: a) selecao e controle das doadoras, b) caracterizacao do leite humano ordenhado (fisico-quimica, microbiologica e imunologica), c) estudo dos fatores que afetam a qualidade microbiologica do leite humano durante a ordenha, e d) estudo dos tratamentos para preservacao do leite humano. As amostras foram provenientes de 19 doadoras do Banco de Leite Humano do Instituto Fernandes Figueira, que conduziam as ordenhas por expressao manual sob condicoes controladas. Os fatores inerentes as doadoras, tais como periodo de lactacao, cor, idade, tempo de amamentacao anterior e numero de filhos, nao exerceram influencia estatisticamente significativa sobre o volume de leite produzido pelas doadoras e nem sobre as caracteristicas fisico-quimicas avaliadas. Os valores de pH, e acidez (D) e o indice crioscopico nao apresentaram correlacao estatisticamente significativa. O estudo comparativo dos procedimentos higienico-sanitarios adotados pelas doadoras e o do proposto neste trabalho mostraram que e possivel melhorar significativamente a qualidade do leite. Os resultados das analises microbiologicas de amostras obtidas segundo o metodo proposto revelaram uma reducao substancial na contaminacao do leite com mesofilos e estafilococos, assim como a ausencia de microrganismos pertencentes aos grupos coliformes, psicotroficos, termoduricos, termoduricos-psicotroficos, fungos e leveduras, praticamente restringem o leite da ocorrencia de microrganismos pertencentes a contaminacao primaria, o que se traduz como uma substancial melhora da qualidade microbiologica do leite humano ordenhado. As analises microbiologicas revelaram, ainda, que cada mama, individualmente, e capaz de exercer grande influencia sobre a qualidade microbiologica final do leite humano, e que a populacao microbiana variou consideravelmente ao longo da ordenha, sempre de forma decrescente. Os resultados mostraram uma reducao media de 76,2 por cento da populacao microbiana entre os primeiros 10 e 20 ml ordenhados. Diante do exposto, verifica-se que a qualidade microbiologica do leite pode ser significativamente melhorada por meio da adocao de adequadas tecnicas higienico-sanitarias e pela eliminacao dos primeiros 10-20ml de leite ordenhados. O efeito dos tratamentos visando a preservacao do leite human.

Available in PDF, EPUB and Kindle. Book excerpt: Biofuel is a renewable energy source produced from natural materials. The benefits of biofuels over traditional petroleum fuels include greater energy security, reduced environmental impact, foreign exchange savings, and socioeconomic issues related to the rural sector. The most common biofuels are produced from classic food crops that require high-quality agricultural land for growth. However, bioethanol can be produced from plentiful, domestic, cellulosic biomass resources such as herbaceous and woody plants, agricultural and forestry residues, and a large portion of municipal and industrial solid waste streams. There is also a growing interest in the use of vegetable oils for making biodiesel. “Biofuels: Securing the Planet’s Future Energy Needs” discusses the production of transportation fuels from biomass (such as wood, straw and even household waste) by Fischer-Tropsch synthesis. The book is an important text for students and researchers in energy engineering, as well as professional fuel engineers.

Book excerpt: The factors affecting the presence and growth of micro-organisms in piped networks are reviewed in this book, as are the practices of water supply organisations that can directly or indirectly influence their presence and growth. The information and conclusions are intended for policy makers and those responsible for formulating "Water Safety Plans" for the supply of drinking-water. It is also relevant to engineers and scientists who are responsible for water supply planning, operations and monitoring. The review shows that there are often public health reasons for adopting a more proactive approach to many of the traditional practices used in designing, operating and maintaining distribution networks, and to modifying the composition of the water that is fed into the network. Contents include the following topics: The microbiology of piped distribution systems and public health Composition of treated waters to minimise potential for microbiological changes Design and operation of distribution networks. Planned maintenance and survey of distribution systems Precautions during construction and repairs Small animals in drinking water distribution systems Risk management for distribution systems

Book excerpt: Dengue and its potentially fatal forms, dengue henorrhagic fever and dengue shock syndrome, once more threaten much of the Americas. In the 1980s the vector control programmes fell victim to the cutbacks in public health expenditure and their responses to dengue outbreaks tended to be a little too late. These guidelines have risen to the challenge by incorporating all aspects of the prevention and control of the disease and its vectors. In addition, because dengue is primarily a problem of domestic sanitation and households can combat the problem inexpensively. The guidelines enmphasize ways to transfer responsibility for dengue control and prevention to the community."
