The need for the development of techniques based on the characteristics of the viral proteins and genomic nucleic acids was realized in order to detect, identify, differentiate and quantify viruses in the infected plants/planting materials with or without symptoms of infection. Immunoassays have been successfully applied for the detection of viruses in crop and weed host plant species as well as in the vectors. Nucleic acid-based techniques have been demonstrated to be the most reliable and sensitive tests for detection, identification and differentiation of viruses and viroids present in plants and planting materials.. Inclusion of numerous protocols in appropriate chapters as appendix is a unique feature of this volume.

The Purpose of this book is to provide a helpful reference for invertebrate pathologist, virologists, and electron microscopists on invertebrate viruses. Investigators from around the world have shared their expertise in order introduce scientists to the exciting advances in invertebrate virology.

Viruses: Molecular Biology, Host Interactions, and Applications to Biotechnology provides an up-to-date introduction to human, animal and plant viruses within the context of recent advances in high-throughput sequencing that have demonstrated that viruses are vastly greater and more diverse than previously recognized. It covers discoveries such as the Mimivirus and its virophage which have stimulated new discussions on the definition of viruses, their place in the current view, and their inherent and derived 'interactomics' as defined by the molecules and the processes by which virus gene products interact with themselves and their host's cellular gene products. Further, the book includes perspectives on basic aspects of virology, including the structure of viruses, the organization of their genomes, and basic strategies in replication and expression, emphasizing the diversity and versatility of viruses, how they cause disease and how their hosts react to such disease, and exploring developments in the field of host-microbe interactions in recent years. The book is likely to appeal, and be useful, to a wide audience that includes students, academics and researchers studying the molecular biology and applications of viruses

The fourth volume of "Advances in Antiviral Drug Design" is keeping up with the recent progress made in the broad field of antiviral drug research and encompasses six specific directions that have opened new avenues for the treatment of HIV and other virus infections.
First, as the introductory chapter, the different new anti-HIV agents that are now in preclinical or clinical development are reviewed by E. De Clercq. This includes new NRTIs, NNRTIs and PIs, but also HIV entry/fusion inhibitors as well as integrase inhibitors, and some of these agents, such as the NRTI emtricitabine [(-)FTC] and the PI atazanavir, may soon be licensed for clinical use.
Second, high expectations are vested in the potential therapeutic usefulness of inhibitors of HIV integration, a point of no return in the life cycle of HIV, and this approach is highlighted by D.J. Hazuda and S.D. Young.
Third, as all currently available PIs can be described as "peptidomimetic," and, therefore, expected to demonstrate overlapping virus-drug resistance and side effect profiles, it would be interesting to see how a non-peptidic protease inhibitor such as tipranavir behaves, and this is covered by D. Mayers, K. Curry, V. Kohlbrenner and S. McCallister.
Fourth, neuraminidase inhibitors such as zanamivir (that has to be inhaled) and oseltamivir (that can be administered via the oral route) have gained a definitive status as antiviral drugs useful for both therapy and prophylaxis of influenza A and B virus infections; as they target a specific influenza viral enzyme, neuraminidase (or sialidase), they may be expected to block newly emerging influenza viruses as well, and the design of neuraminidase inhibitorshas received due attention of H. Jin and C.U. Kim.
Fifth, while the major current efforts in antiviral drug development have shifted from herpesviruses towards HIV and hepatitis viruses [hepatitis B virus (HBV), hepatitis C virus (HCV)], it is interesting to note that by switching from the classical five-membered sugar or acyclic nucleoside strategy, J. Wang, M. Froeyen and P. Herdewijn have gone "upstream" in designing six-membered carbocyclic nucleosides as potential anti-herpesvirus agents.
Sixth, following up on the nucleotide prodrug strategy introduced above under ix, to deliver the biologically active nucleotides inside the cells, C. Meier has elaborated on a particular class of such pronucleotides, namely that of the cyclosaligenyl pronucleotides, an approach that should have far reaching implications for compounds effective against HIV, HBV and other viruses.
The six topics covered in this fourth volume of "Advances in Antiviral Drug Design" are in the front line of the present endeavors towards the design and development of new therapeutic agents for virus infections. They pertain to the combat against three of the most important viral pathogens of current times: HIV, HBV, influenza virus and herpesviruses.

Viruses: From Understanding to Investigation provides students with a map for lifetime learning by presenting the definition and unique characteristics of viruses, including major topics, such as the virus lifecycle, structure, taxonomy, evolution, history, host-virus interactions and methods to study viruses. In addition, the book assesses the connections between, and among, the aforementioned topics, providing an integrated approach and in-depth understanding of how viruses work.

First published in 1953, this series covers a diverse range of in-depth reviews, providing a valuable overview of the current field of virology. The series is a valuable resource for information on all topics of virus research, from bacteriophages to human viruses, with this volume focusing on genomics.

Principles of Virology, the leading virology textbook in use, is an extremely valuable and highly informative presentation of virology at the interface of modern cell biology and immunology. This text utilizes a uniquely rational approach by highlighting common principles and processes across all viruses. Using a set of representative viruses to illustrate the breadth of viral complexity, students are able to under-stand viral reproduction and pathogenesis and are equipped with the necessary tools for future encounters with new or understudied viruses. This fifth edition was updated to keep pace with the ever-changing field of virology. In addition to the beloved full-color illustrations, video interviews with leading scientists, movies, and links to exciting blogposts on relevant topics, this edition includes study questions and active learning puzzles in each chapter, as well as short descriptions regarding the key messages of references of special interest. Volume I: Molecular Biology focuses on the molecular processes of viral reproduction, from entry through release. Volume II: Pathogenesis and Control addresses the interplay between viruses and their host organisms, on both the micro- and macroscale, including chapters on public health, the immune response, vaccines and other antiviral strategies, viral evolution, and a brand new chapter on the therapeutic uses of viruses. These two volumes can be used for separate courses or together in a single course. Each includes a unique appendix, glossary, and links to internet resources. Principles of Virology, Fifth Edition, is ideal for teaching the strategies by which all viruses reproduce, spread within a host, and are maintained within populations. This edition carefully reflects the results of extensive vetting and feedback received from course instructors and students, making this renowned textbook even more appropriate for undergraduate and graduate courses in virology, microbiology, and infectious diseases.

Influenza, 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 book focuses on those virus families that are found primarily or exclusively in insects, covering all major families of insect-selective viruses except for the baculoviruses which were described in a previous volume of "The Viruses" series. The topics include: the large DNA viruses; the small DNA densoviruses; the RNA viruses; and, the arbovirus expression systems and their potential employment in the future. Ninety-eight illustrations supplement the text.

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.

Foodborne viruses are an important group of pathogens recognized to cause significant disease globally, in terms of both number of illnesses and severity of disease. Contamination of foods by enteric viruses, such as human norovirus and hepatitis A and E viruses, is a major concern to public health and food safety. Food Virology is a burgeoning field of emphasis for scientific research. Many developments in foodborne virus detection, prevention and control have been made in recent years and are the basis of this publication. This second edition of Viruses in Foods provides an up-to-date description of foodborne viruses of public health importance, including their epidemiology and methods for detection, prevention and control. It uniquely includes case reports of past outbreaks with implications for better control of future outbreaks, a section that can be considered a handbook for foodborne virus detection, and updated and expanded information on virus prevention and control, with chapters on natural virucidal compounds in foods and risk assessment of foodborne viruses.

This book is an excellent, up-to-date reference on a relatively young area of research in which virology, cellular biology and molecular pathogenesis govern the principles of coinvestigation. Thus, the book will be of great interest to virologists, molecular immunologists and biologists, and biochemists but also to clinical pharmacologists in the long-term search for new antiviral agents. Ulrich Desselberger, Gif-sur-Yvette/Cambridge. Infection of a naive (non-immune) host with a virus elicits an immediate response which results in a cascade of changes in the host, including an interferon response (innate immunity). The outcome of this interaction is influenced by the genes of the virus as well as the genes of the host. Interestingly, different viruses do it in different ways. Not only is there a plethora of mechanisms used by the invading organisms, but the host has also evolved a great variety of redundant and robust countermeasures. This interplay of host and virus represents one of the most significant frontiers in biology today. A clearer understanding of the mechanisms involved will arm us with better strategies to deal with viruses, including emerging pathogens and potential bioterrorism agents. This book is sure to benefit students, scientists, and physicians working in the areas of virology, immunology, microbiology, and infectious diseases. Pharmaceutical industry professionals will also find interest in this illuminating look into virus/host interactions.

The seminal text "Plant Virology" is now in its fifth edition. It has been 10 years since the publication of the fourth edition, during which there has been an explosion of conceptual and factual advances.

The scope of the book is very broad, covering a wide range of areas in HBV/HDV and HCV research, including both basic and clinical science. The selected topics range from epidemiology, immunology, molecular virology and oncology, to clinical therapy.Chronic Hepatitis B and C consists of 14 chapters, each being a review of a special topic on HBV or HCV. While review articles on a special topic can be found in periodical journals, they tend to be more restricted in presentation. Therefore, this book will provide more in-depth coverage of what are presented as "unpublished results" and "data not shown" in journal articles. Furthermore, several authors in this book do not write review articles regularly. Some authors wrote reviews on a specific topic regularly, but they tried a new topic in this book (e.g., Dr. YF Liaw on "natural course," Dr. Shih on "virion release," Dr. Michael Lai on "lymphotropism of HCV," etc. ). Overall, the book will offer useful information at the cutting age.Sample Chapter(s)

Negative strand RNA viruses have a unique mechanism of replication. Their genome is a single strand RNA that has to be transcribed as soon as the virus enters the host in order to carry out viral replication. As a result, a viral-specific RNA polymerase is packaged in the virion and is ready for transcription after virus entry. This novel replication mechanism dictates the assembly and RNA synthesis of negative strand RNA viruses. In recent years, many discoveries have been made with regard to the entry, replication and assembly of this class of viruses. This book will present updated coverage of the fundamental knowledge about negative strand RNA viruses.

Over the last ten years, much effort has been devoted to improving the biophysical techniques used in the study of viruses. This has resulted in the visualization of these large macromolecular assemblages at atomic level, thus providing the platform for functional interpretation and therapeutic design. Structural Virology covers a wide range of topics and is split into three sections. The first discusses the vast biophysical methodologies used in structural virology, including sample production and purification, confocal microscopy, mass spectrometry, negative-stain and cryo-electron microscopy, X-ray crystallography and nuclear magnetic resonance spectroscopy. The second discusses the role of virus capsid protein structures in determining the functional roles required for receptor recognition, cellular entry, capsid assembly, genome packaging and mechanisms of host immune system evasion. The last section discusses therapeutic strategies based on virus protein structures, including the design of antiviral drugs and the development of viral capsids as vehicles for foreign gene delivery. Each topic covered will begin with a review of the current literature followed by a more detailed discussion of experimental procedures, a step in the viral life cycle, or strategies for therapeutic development. With contributions from experts in the field of structural biology and virology this exceptional monograph will appeal to biomedical scientists involved in basic and /or applied research on viruses. It also provides up-to-date reference material for students entering the field of structural virology as well as scientists already familiar with the area.

Topics covered in this book include RNA silencing and its suppression in plant virus infection, virus replication mechanisms, the association of cellular membranes with virus replication and movement, plant genetic resistance to viruses, viral cell-to-cell spread, long distance movement in plants, virus induced ER stress, virus diversity and evolution, virus-vector interactions, cross protection, geminiviruses, negative strand RNA viruses, viroids, and the diagnosis of plant viral diseases using next generation sequencing. This book was anticipated to help plant pathologists, scholars, professors, teachers and advanced students in the field with a comprehensive state-of-the-art knowledge of the subject.

Emerging Topics in Physical Virology is a state-of-the-art account of recent advances in the experimental analysis and modeling of structure, function and dynamics of viruses. It is the first interdisciplinary book that integrates a review of relevant experimental techniques, such as cryo-electron microscopy, atomic force microscopy and mass spectrometry with the latest results on the biophysical and mathematical modeling of viruses. The book comprehensively covers the structure and physical properties of the protein envelopes that encapsulate and hence protect the delicate viral genome, their assembly and disassembly, the organization of the viral genome, infection, evolution, as well as applications of viruses in Biomedical Nanotechnology. It is an essential primer for scientists working in all aspects of virology, including the increasing use of viruses and virus-like particles in bio- and nano-technology. Its review style makes it moreover suitable for non-experts as an introduction into this exciting research area.

This book captures some of the essential developments, both historical and current, relating to the human retroviruses and the diseases they cause. It describes detailed molecular biology and epidemiology of human T-leukemia virus type 1 (HTLV-1).

Since the first edition of "Vaccinia Virus and Poxvirology: Methods and Protocols" was published, a number of important events related to poxvirology have occurred, such as FDA approval of a culture-based live smallpox vaccine and the vaccination of large numbers of U.S. military and relatively large numbers of U.S. civilians.Novel anti-poxvirus therapeutics have been developed and have been used in emergency settings.

A journey through the history and science of epidemics and pandemics – from measles to coronavirus.

For centuries mankind has waged war against the infections that, left untreated, would have the power to wipe out communities, or even entire populations. Yet for all our advanced scientific knowledge, only one human disease – smallpox – has ever been eradicated globally. In recent years, outbreaks of Ebola and Zika have provided vivid examples of how difficult it is to contain an infection once it strikes, and the panic that a rapidly spreading epidemic can ignite.

But while we chase the diseases we are already aware of, new ones are constantly emerging, like the coronavirus that spread across the world in 2020. At the same time, anti-microbial resistance is harnessing infections that we once knew how to control, enabling them to thrive once more.

Meera Senthilingam presents a timely look at humanity’s ongoing battle against infection, examining the successes and failures of the past, along with how we are confronting the challenges of today, and our chances of eradicating disease in the future.

This book describes the role of the obligate inhabitants of all vertebrate genomes-endogenous retroviruses, especially those emerged in genomes rather recently, during primate evolution. It specially focuses on human endogenous retroviruses as well as other retroelements.
