Download or read book Methods For Recovering Viruses From The Environment written by Gerald Berg and published by CRC Press. This book was released on 2018-01-18 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book argues, that without methods, there can be no research. Effective research requires effective methods, not always easy to come by. The development of methods in environmental virology became a focus of growing interest about two decades ago. Progress has been significant since that time in pure experimental systems, where there are no interferences, consistent high recoveries of viruses from environmental waters has been achievable for some time. In the natural environment, however, in relatively clean waters, substances such as humic and fulvic acids interfere with viral recoveries and average recovery rates probably do not reach 20%. With sewage sludges and shellfish, recoveries are undoubtedly much lower. Yet, even relatively low viral recovery rates have made possible the detection of viral hazards in drinking waters. The hazards that exist are undoubtedly much greater than those demonstrated with the relatively inefficient methods inefficient methods developed thus far. Improving methods, as they are developed in the years to come, will undoubtedly bring the true extent of the hazards into better perspective.
Download or read book Virus Ecology and Disturbances Impact of Environmental Disruption on the Viruses of Microorganisms written by Stephen Tobias Abedon and published by Frontiers Media SA. This book was released on 2015-03-26 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viruses infect numerous microorganisms including, predominantly, Bacteria (bacteriophages or phages) but also Archaea, Protists, and Fungi. They are the most abundant and ubiquitous biological entities on Earth and are important drivers of ecosystem functioning. Little is known, however, about the vast majority of these viruses of microorganisms, or VoMs. Modern techniques such as metagenomics have enabled the discovery and description of more presumptive VoMs than ever before, but also have exposed gaps in our understanding of VoM ecology. Exploring the ecology of these viruses – which is how they interact with host organisms, the abiotic environment, larger organisms, and even other viruses across a variety of environments and conditions – is the next frontier. Integration of a growing molecular understanding of VoMs with ecological studies will expand our knowledge of ecosystem dynamics. Ecology can be studied at multiple levels including individual organisms, populations, communities, whole ecosystems, and the entire biosphere. Ecology additionally can consider normal, equilibrium conditions or instead perturbations. Perturbations are of particular interest because measuring the effect of disturbances on VoM-associated communities provides important windows into how VoMs contribute to ecosystem dynamics. These disturbances in turn can be studied through in vitro, in vivo, and in situ experimentation, measuring responses by VoM-associated communities to changes in nutrient availability, stress, physical disruption, seasonality, etc., and could apply to studies at all ecological levels. These are considered here across diverse systems and environments.

Available in PDF, EPUB and Kindle. Book excerpt: We have attempted to provide a concise and up to date account of human viruses in the environment with attention to basic tools now available for monitoring viruses. We have aimed this introductory volume at young students, teachers and investigators in microbiology, virology, environmental engineering and health sciences. As the routes for virus dissemination become more varied, there is an enhanced potential for causing infection in humans. Improvement in the development of control strategies will alleviate the magnitude of viral pollution of the environment. This volume will introduce the reader to an area of science which of necessity must utilize a variety of disciplines. V.CHALAPATIRAO JOSEPH L.

Available in PDF, EPUB and Kindle. Book excerpt: A renaissance of virus research is taking centre stage in biology. Empirical data from the last decade indicate the important roles of viruses, both in the evolution of all life and as symbionts of host organisms. There is increasing evidence that all cellular life is colonized by exogenous and/or endogenous viruses in a non-lytic but persistent lifestyle. Viruses and viral parts form the most numerous genetic matter on this planet.

Available in PDF, EPUB and Kindle. Book excerpt: Zoonotic Viruses of Northern Eurasia: Taxonomy and Ecology provides a review of modern data of the taxonomy, distribution, and ecology of zoonotic viruses in the ecosystems of Northern Eurasia. With climate changes, increasing population density of arthropod vectors and vertebrate hosts, development of unused lands, transferences of viruses by birds, bats, infected humans, and animals, vectors allow virus populations to adapt to the new environment. This leads to the appearance of emerging or re-emerging infections. This book presents data about circulation and evolution of influenza viruses, tick-borne encephalitis virus, West Nile virus, Crimean-Congo hemorrhagic fever virus, hantaviruses, Sindbis virus, California encephalitis group viruses and other pathogenic viruses as well as of novel viruses classified for the first time using next-generation sequence. Features summarized data about the circulation of approximately 80 viruses isolated in natural foci of Northern Eurasia Provides descriptions of the main ecosystems of Northern Eurasia in the context of the ecology of viruses with environmental factors Delineates the potential impact of climate change for the distribution of viruses Includes virus taxonomy, ecology, distribution and pathogenicity for humans and animals

Download or read book Viruses and Environment written by Edouard Kurstak and published by Elsevier. This book was released on 2012-12-02 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: Viruses and Environment contains the proceedings of the Third International Conference on Comparative Virology, held at Mont Gabriel, Quebec, Canada on May 1977. The primary focus of the conference is the ecology of viruses, that is, the interrelationships between organisms and their environment. Organized into seven parts with a total of 33 chapters, this book centers on the impact of viruses on the environment; the persistent virus infections of man, vertebrate and invertebrate animals, and plants; and the smallest disease agents, the viroids. In particular, this book describes the reservoirs of viruses, such as arthropod vectors, water, cultivated plants, and wild animals; safety considerations concerning the use of live virus vaccines; and the viral insecticides. The use of bacterial viruses in genetic engineering is also addressed. This treatise will be valuable to research workers in medical and biomedical fields; biological control; and animal and plant quarantine. It will also benefit the university teachers and graduate students.
