Some Rna Viruses

This book provides an overview of the globally concerning and emerging public health RNA viruses like SARS-CoV2, Ebola virus, FMD disease, and others. The main drive to publish this book was to present information on the molecular epidemiology pattern, transmission dynamics, host response factor, RNA viral infection, RNA virus evolution, molecular biology of RNA viruses, pathogenesis mechanism and phylogenetic analysis causing viral diseases among humans. This book will help to provide updated research information to the policymaker or planner for further diagnosis with genotyping tools, control, and prevention for further outbreaks of diseases from RNA viruses in tropical and subtropical countries.

Virus Structure covers the full spectrum of modern structural virology. Its goal is to describe the means for defining moderate to high resolution structures and the basic principles that have emerged from these studies. Among the topics covered are Hybrid Vigor, Structural Folds of Viral Proteins, Virus Particle Dynamics, Viral Gemone Organization, Enveloped Viruses and Large Viruses. Covers viral assembly using heterologous expression systems and cell extracts Discusses molecular mechanisms in bacteriophage T7 procapsid assembly, maturation and DNA containment Includes information on structural studies on antibody/virus complexes

Many RNA viruses have been known for decades to be genetically and biologically quite variable. Some well-known examples are influenza viruses, foot and mouth disease viruses, and Newcastle disease virus. During the past decade, it has become clear that most, it not all. , RNA viruses (riboviruses and retroviruses) are much more mutable than was recognized previously, and that this great mutability generates extremely complex populations consisting of indeterminate mixtures of related variants (Le. , "mutant swarms" or "quasispecies" populations). This is also true of DNA viruses (such as hepatitis DNA genomes via RNA transcripts B virus) which replicate their that are reverse-transcribed back to DNA. This hypermutability of RNA replicons provides great biological adaptability for RNA virus genomes. It also allows (but does not necessitate) RNA viruses, so that they can extremely rapid evolution of evolve over a million times more quickly than their eukaryotic DNA-based hosts. The genetics of RNA replicons is so unusual (and often counterintuitive) that it has many important biological conse quences which are neither readily apparent nor widely under stood. Failure to understand the distinctive aspects of RNA genetics frequently generates confusion and controversy and can adversely impact vaccine and antiviral drug programs and other applications of medical virology. The 14 chapters in this volume describe advances in a number of significant areas of RNA virus genetics and evolution.

RNA Viruses: A Practical Approach is wide ranging in scope, from emerging technology such as reverse genetics and retrovirus vectors, to money saving tips - how to make your own silica particles for high efficiency RNA extraction and liposomes for cell transfection! Chapter one covers the fundamentals of investigating RNA virus genome structure at a molecular level. Chapters two and three describe techniques for mutagenesis of RNA genomes and analysis of transcription. Chapter four deals with RNA virus-encoded proteinases, an important aspect of the control of RNA virus gene expression. Chapter five considers retrovirus oncogenesis and chapter six analysis of RNA virus quasispecies. Chapter seven describes systems for investigation of in vitro replication of positive-stranded viruses and chapter eight the packaging of RNA virus genomes. In addition to the technical aspects of reverse genetics and retrovirus vectors, both of the final two chapters also consider ethical aspects of these new technologies.

Reverse genetics, the genetic manipulation of RNA viruses to create a wild-type or modified virus, has led to important advances in our understanding of viral gene function and interaction with host cells. Since many severe viral human and animal pathogens are RNA viruses, including those responsible for polio, measles, rotaviral diarrhoea and influenza infections, it is also an extremely powerful technique with important potential application for the prevention and control of a range of human and animal viral diseases. Reverse Genetics of RNA Viruses provides a comprehensive account of the very latest developments in reverse genetics of RNA viruses through a wide range of applications within each of the core virus groups including; positive sense, negative sense and double stranded RNA viruses. Written by a team of international experts in the field, it provides a unique insight into how the field has developed, what problems are being addressed now and where applications may lead in the future. It will prove invaluable to bioscience, medical and veterinary students, those starting research in this area as well as other researchers and teachers needing to update their knowledge of this fast-moving field. An authoritative, comprehensive overview of reverse genetics in RNA Viruses. Includes numerous examples of cutting- edge applications of reverse genetics within each of the RNA viral groups. Written by a team of international experts, including some of the leading researchers in the field.

This book is a collection of critical reviews about a diverse group of virus families with two features in common: the stable repository of genetic information in each virus is RNA, and each virus modifies and appropriates a particular patch of the eukaryotic cell membrane system to complete its structure. The reviews take the reader from the level of virus genome structure and expression through the quaternary interactions between virus-specified elements and cellular components that cooperate to produce virus particles. There are spectacular illustrations in this volume, but it is much more than a picture gallery. Reading widely in this book can be an effective antidote to overspecialization: in these pages, you are likely to learn much about viruses and about cells that you didn't know before; you'll discover illuminating parallels between diverse virus families; you'll come away with a sharpened awareness of important things that are still to be learned. Memphis, Tenn. , Summer 1984 David W. Kingsbury Preface This book was written at the suggestion of Dr. David W. Kingsbury made at a work shop on viruses organized by the Multiple Sclerosis Society in Aspen, Colorado, U. S. A. , three years ago. Originally, we had thought to focus on the morphological aspects of viral assembly. Later, during our discussions on the process of budding of enveloped RNA viruses, it became evident that we should include biochemical data in our review and correlate them with the structural aspects of virus maturation.

While the study of viral evolution has developed rapidly in the last 30 years, little attention has been directed toward linking the mechanisms of viral evolution to the epidemiological outcomes of these processes. This book intends to fill this gap by considering the patterns and processes of viral evolution at all its spatial and temporal scales.

Completely revised and updated, the new edition of this groundbreaking text integrates basic virology with pathophysiological conditions to examine the connection between virology and human disease. Most virology textbooks focus on the molecular biology involved without adequate reference to physiology. This text focuses on viruses that infect humans, domestic animals and vertebrates and is based on extensive course notes from James Strauss’ virology class at the California Institute of Technology taught for over 30 years. Expertly depicting in color the molecular structure and replication of each virus, it provides an excellent overview for students and professionals interested in viruses as agents of human disease. Includes over 30% new material - virtually all of the figures and tables have been redrawn to include the latest information and the text has been extensively rewritten to include the most up-to-date information Includes a new chapter on emerging and reemerging viral diseases such as avian flu, SARS, the spread of West Nile virus across America, and the continuing spread of Nipah virus in Southeast Asia Further reading sections at the end of each chapter make it easy find key references World maps depicting the current distribution of existing and newly emerging viruses are also incorporated into the text
