Book Synopsis Bacteriophage Ecology by : Stephen T. Abedon
Download or read book Bacteriophage Ecology written by Stephen T. Abedon and published by Cambridge University Press. This book was released on 2008-05-01 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacteriophages, or phages, are viruses that infect bacteria and are believed to be the most abundant and genetically diverse organisms on Earth. As such, their ecology is vast both in quantitative and qualitative terms. Their abundance makes an understanding of phage ecology increasingly relevant to bacterial ecosystem ecology, bacterial genomics and bacterial pathology. Abedon provides the first text on phage ecology for almost 20 years. Written by leading experts, synthesizing the three key approaches to studying phage ecology, namely studying them in natural environments (in situ), experimentally in the lab, or theoretically using mathematical or computer models. With strong emphasis on microbial population biology and distilling cutting-edge research into basic principles, this book will complement other currently available volumes. It will therefore serve as an essential resource for graduate students and researchers, particularly those with an interest in phage ecology and evolutionary biology.

Download or read book Bacteriophages in Health and Disease written by Paul Hyman and published by CABI. This book was released on 2012 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacteriophages are viruses that infect bacteria; as such, they have many potential uses for promoting health and combating disease. This book covers the many facets of phage-bacterial-human interaction in three sections: the role and impact of phages on natural bacterial communities, the potential to develop phage-based therapeutics and other aspects in which phages can be used to combat disease, including bacterial detection, bacterial epidemiology, the tracing of fecal contamination of water and decontamination of foods.
Book Synopsis The Bacteriophages by : Richard Calendar
Download or read book The Bacteriophages written by Richard Calendar and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has been 10 years since Plenum included a series of reviews on bacte riophages, in Comprehensive Virology. Chapters in that series contained physical-genetic maps but very little DNA sequence information. Now the complete DNA sequence is known for some phages, and the se quences for others will soon follow. During the past 10 years two phages have come into common use as reagents: A phage for cloning single copies of genes, and Ml3 for cloning and DNA sequencing by the dideoxy termi nation method. Also during that period the use of alternative sigma fac tors by RNA polymerase has become established for SPOl and T4. This seems to be a widely used mechanism in bacteria, since it has been implicated in sporulation, heat shock response, and regulation of nitro gen metabolism. The control of transcription by the binding of A phage CII protein to the -35 region of the promoter is a recent finding, and it is not known how widespread this mechanism may be. This rapid progress made me eager to solicit a new series of reviews. These contributions are of two types. Each of the first type deals with an issue that is exemplified by many kinds of phages; chapters of this type should be useful in teaching advanced courses. Chapters of the second type provide comprehensive pictures of individual phage families and should provide valuable information for use in planning experiments.
Book Synopsis Viruses: More Friends Than Foes (Revised Edition) by : Karin Moelling
Download or read book Viruses: More Friends Than Foes (Revised Edition) written by Karin Moelling and published by World Scientific. This book was released on 2020-08-26 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coronavirus, AIDS, and Ebola: Viruses are normally defined as pathogens. Most viruses are, however, not enemies or killers. Well-known virologist and cancer researcher Karin Moelling describes surprising insights about a completely new and unexpected world of viruses. Viruses are ubiquitous, in the oceans, our environment, in animals, plants, bacteria, in our body, even in our genomes. They influence our weather, can contribute to control obesity, and can surprisingly be applied against threatening multi-resistant bacteria. The success story of the viruses started more than 3.5 billion years ago in the dawn of life when even cells did not exist. They are the superpower of life. There are more viruses on earth than stars in the sky. Viruses are everywhere. Some of them are incredibly ancient. Many viruses are hundredfold smaller than bacteria, but others are tenfold bigger and they were discovered only recently — the giant viruses, even deep within the permafrost where they were reactivated after 30,000 years.The author talks about a completely new world of viruses, which are based on the most recent, in part her own research results. Could viruses have been our oldest ancestors? Have viruses even 'invented' social behavior, do they lead to geniuses such as Mozart or Einstein — or alternatively to cancer? They can help to cure cancer. In this book, the author made a clear distinction between what is fact and what is her vision. This book is written for a general audience and not just for the experts. Its aim is to stimulate thinking, and perhaps to attract more young scientists to enter this field of research.This revised edition is brought up to date by a new chapter on the SARS-CoV-2 pandemic.

Book Synopsis Viruses: Essential Agents of Life by : Günther Witzany
Download or read book Viruses: Essential Agents of Life written by Günther Witzany and published by Springer Science & Business Media. This book was released on 2012-11-13 with total page 432 pages. 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.
Download or read book The Pangenome written by Hervé Tettelin and published by Springer Nature. This book was released on 2020-04-30 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book offers the first comprehensive account of the pan-genome concept and its manifold implications. The realization that the genetic repertoire of a biological species always encompasses more than the genome of each individual is one of the earliest examples of big data in biology that opened biology to the unbounded. The study of genetic variation observed within a species challenges existing views and has profound consequences for our understanding of the fundamental mechanisms underpinning bacterial biology and evolution. The underlying rationale extends well beyond the initial prokaryotic focus to all kingdoms of life and evolves into similar concepts for metagenomes, phenomes and epigenomes. The book’s respective chapters address a range of topics, from the serendipitous emergence of the pan-genome concept and its impacts on the fields of microbiology, vaccinology and antimicrobial resistance, to the study of microbial communities, bioinformatic applications and mathematical models that tie in with complex systems and economic theory. Given its scope, the book will appeal to a broad readership interested in population dynamics, evolutionary biology and genomics.

Book Synopsis Phage Therapy: Past, Present and Future by : Stephen T. Abedon
Download or read book Phage Therapy: Past, Present and Future written by Stephen T. Abedon and published by Frontiers Media SA. This book was released on 2017-09-05 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, the first observation of a transmissible lytic agent that is specifically active against a bacterium (Bacillus anthracis) was by a Russian microbiologist Nikolay Gamaleya in 1898. At that time, however, it was too early to make a connection to another discovery made by Dmitri Ivanovsky in 1892 and Martinus Beijerinck in 1898 on a non-bacterial pathogen infecting tobacco plants. Thus the viral world was discovered in two of the three domains of life, and our current understanding is that viruses represent the most abundant biological entities on the planet. The potential of bacteriophages for infection treatment have been recognized after the discoveries by Frederick Twort and Felix d’Hérelle in 1915 and 1917. Subsequent phage therapy developments, however, have been overshadowed by the remarkable success of antibiotics in infection control and treatment, and phage therapy research and development persisted mostly in the former Soviet Union countries, Russia and Georgia, as well as in France and Poland. The dramatic rise of antibiotic resistance and especially of multi-drug resistance among human and animal bacterial pathogens, however, challenged the position of antibiotics as a single most important pillar for infection control and treatment. Thus there is a renewed interest in phage therapy as a possible additive/alternative therapy, especially for the infections that resist routine antibiotic treatment. The basis for the revival of phage therapy is affected by a number of issues that need to be resolved before it can enter the arena, which is traditionally reserved for antibiotics. Probably the most important is the regulatory issue: How should phage therapy be regulated? Similarly to drugs? Then the co-evolving nature of phage-bacterial host relationship will be a major hurdle for the production of consistent phage formulae. Or should we resort to the phage products such as lysins and the corresponding engineered versions in order to have accurate and consistent delivery doses? We still have very limited knowledge about the pharmacodynamics of phage therapy. More data, obtained in animal models, are necessary to evaluate the phage therapy efficiency compared, for example, to antibiotics. Another aspect is the safety of phage therapy. How do phages interact with the immune system and to what costs, or benefits? What are the risks, in the course of phage therapy, of transduction of undesirable properties such as virulence or antibiotic resistance genes? How frequent is the development of bacterial host resistance during phage therapy? Understanding these and many other aspects of phage therapy, basic and applied, is the main subject of this Topic.

Book Synopsis Bacteriophages by : Pilar García Suárez
Download or read book Bacteriophages written by Pilar García Suárez and published by MDPI. This book was released on 2020-11-24 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is talk of an upcoming antibiotic armageddon, with untreatable post-operative infections, and similarly untreatable complications after chemotherapy. Indeed, the now famous “O’Neill Report” (https://amr-review.org/) suggests that, by 2050, more people might die from antibiotic-resistant bacterial infections than from cancer. While we are still learning all the subtle drivers of antibiotic resistance, it seems increasingly clear that we need to take a “one health” approach, curtailing the use of antibiotics in both human and veterinary medicine. However, there are no new classes of antibiotics on our horizon. Maybe something that has been around “forever” can come to our rescue—bacteriophages! Nevertheless, it is also necessary to do things differently, and use these new antimicrobials appropriately. Therefore, an in-depth study of bacteriophage biology and case-by-case applications might be required. Whilst by no means comprehensive, this book does cover some of the many topics related to bacteriophages as antimicrobials, including their use in human therapy and aquaculture. It also explores the potential use of phage endolysins as substitutes of antibiotics in two sectors where there is an urgent need—human therapy and the agro-food industry. Last but not least, there is an excellent perspective article on phage therapy implementation.
Book Synopsis Microbial Megaplasmids by : Edward Schwartz
Download or read book Microbial Megaplasmids written by Edward Schwartz and published by Springer Science & Business Media. This book was released on 2009-01-29 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: Megaplasmids are extrachromosomal genetic elements in the size range of 100 kb and larger. They are found in physiologically and phylogenetically diverse groups of bacteria and archaea. By definition, megaplasmids are not essential for the viability of their hosts under all growth conditions, but paradoxically many megaplasmids carry the genetic information for the defining and characteristic traits of the organism in which they reside. Microbial Megaplasmids reviews our knowledge of the extensively studied representatives, such as the catabolic plasmids of the pseudomonads, the rhizobial Sym plasmids, the Ti plasmids of the genus Agrobacterium and the giant enterobacterial virulence plasmids. It also presents snapshots of more recently discovered megaplasmids. The contribution of megaplasmids to the biology of their hosts is described, highlighting the interactions between megaplasmid and chromosomal genes.
Book Synopsis Prokaryotes and Evolution by : Jean-Claude Bertrand
Download or read book Prokaryotes and Evolution written by Jean-Claude Bertrand and published by Springer. This book was released on 2019-01-01 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this book is to show the essential and indispensable role of prokaryotes in the evolution of aliving world. The evolutionary success of prokaryotes is explained together with their role in the evolution of the geosphere, the biosphere and its functioning, as well as their ability to colonize all biotopes, including the most extreme ones. We consider that all past and present living beings emerged from prokaryotes and have interacted with them. Forces and mechanisms presented in the various theories of evolution apply to prokaryotes. The major stages of their evolution and biodiversity are also described. Finally, it is emphasized that prokaryotes are living organisms that provide indisputable evidence of evolutionary processes. Many examples of ongoing evolution in prokaryotes, observable at the human scale, are provided.
