Abstract

New viral diseases are emerging continuously. Viruses adapt to new environments at astounding rates. Genetic variability of viruses jeopardizes vaccine efficacy. For many viruses mutants resistant to antiviral agents or host immune responses arise readily, for example, with HIV and influenza. These variations are all of utmost importance for human and animal health as they have prevented us from controlling these epidemic pathogens. This book focuses on the mechanisms that viruses use to evolve, survive and cause disease in their hosts. Covering human, animal, plant and bacterial viruses, it p

Abstract

Are infectious diseases caused by novel entities, viruses that have rapidly evolved into more pathogenic forms, or viruses that have crossed species divides and become more virulent in their alternative host? These questions and how new diseases such as AIDS emerged have prompted renewed interest in the ways viruses originated and co-evolved with their hosts.Origin and Evolution of Viruses presents a full and clear description of general viral concepts and specific viral systems, and provides an excellent foundation to our understanding of how viruses emerged.This unique and com

Abstract

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

Abstract

Wildlife and the zoonotic pathogens they reservoir are the source of most emerging infectious diseases of humans. AIDS, hantavirus pulmonary syndrome, SARS, Monkeypox and the human ehrlichioses are a few examples of the devastating effect achieved by cross-species transmission of viral and bacterial pathogens of wildlife. Many factors contribute to the appearance and spread of a pathogen, including; changes in host/pathogen evolution and interaction, human demographics, behavior and technology, environmental factors, and the availability of health care and a public health infrastructure capable of providing surveillance and interventions aimed at disease prevention and control. Additionally, historical factors and the coalescence of particular circumstances modify the conditions by which pathogens and species have an opportunity to intermix, evolve and spread. This volume provides an overview of zoonotic pathogen emergence with an emphasis on the role of wildlife. The first sections of the book explore the mechanisms by which evolution, biology, pathology, ecology, history, and current context have driven the emergence of different zoonotic agents, the next sections provide specific example of disease emergence linked to wildlife, and the final section offers an overview of current methods directed at the surveillance, prevention and control of zoonotic pathogens at the level of the wildlife host and possible mechanisms to improve these activities. This book will be useful to microbiologists, ecologists, zoologists, entomologists as well as physicians and epidemiologists.

Abstract

This book provides a comprehensive look at the field of plant virus evolution. Individual chapters, written by experts in the field, cover plant virus ecology, emerging viruses, plant viruses that integrate into the host genome, population biology, evolutionary mechanisms and appropriate methods for analysis. It covers RNA viruses, DNA viruses, pararetroviruses and viroids. The book summarizes the recent advances in our understanding of genetic bottlenecks, mutation rates and RNA recombination. It presents a number of ideas that are thought-provoking and make excellent discussion points. It is rounded out by a description of the history of plant virus evolution studies, and the link between evolution and taxonomy. Plant Virus Evolution provides an invaluable resource for researchers, teachers and students in the fields of plant virology and virus evolution.

Abstract

When we think about viruses we tend to consider ones that afflict humans-such as those that cause influenza, HIV, and Ebola. Yet, vastly more viruses infect single-celled microbes. Diverse and abundant, microbes and the viruses that infect them are found in oceans, lakes, plants, soil, and animal-associated microbiomes. Taking a vital look at the "microscopic" mode of disease dynamics, Quantitative Viral Ecology establishes a theoretical foundation from which to model and predict the ecological and evolutionary dynamics that result from the interaction between viruses and their microbial hosts.Joshua Weitz addresses three major questions: What are viruses of microbes and what do they do to their hosts? How do interactions of a single virus-host pair affect the number and traits of hosts and virus populations? How do virus-host dynamics emerge in natural environments when interactions take place between many viruses and many hosts? Emphasizing how theory and models can provide answers, Weitz offers a cohesive framework for tackling new challenges in the study of viruses and microbes and how they are connected to ecological processes-from the laboratory to the Earth system.Quantitative Viral Ecology is an innovative exploration of the influence of viruses in our complex natural world.

Abstract

From bacteria to humans, all life has ways to recognize themselves and differentiate themselves from similar life forms. The ability to recognize similarity can be called group identity or group membership and also relates to group cooperation. Even viruses have the capacity for group identity and cooperation. However, those viruses that stably colonize bacteria can directly affect the group identity of their host. Starting with this virus-host relationship, this book traces the origin and evolution of group identity. By examining the stable, extrachromosomal viruses of bacteria, a strategy has been defined that is used for both virus persistence and group identity; this is the addiction module of phage P1. Thus, this book examines how genetic parasites and addiction modules have been involved in the origin of toxins/antitoxins modules as systems of group identity and immunity. The origin of sensory systems for light and small molecule (pheromone) detection and production, social motility, and programmed cell death are all examined. From the emergence of worms with brains, to vertebrate fish, to insects and tetrapods, olfaction and pheromones were maintained for group identity purposes and linked to addictive social bonding. In the African primates and humans, however, a great colonization by genetic parasites mostly destroyed this pheromone based system of social identity. This compelled primates to evolve enlarged social brains that used vision to learn group identity. Humans additionally evolved an even larger social brain and also developed a mind able to learned language and beliefs to specify group identity.

Abstract

Plant viruses cause many of the most important diseases threatening crops worldwide. Over the last quarter of a century, an increasing number of plant viruses have emerged in various parts of the world, especially in the tropics and subtropics. As is generally observed for plant viruses, most of the emerging viruses are transmitted horizontally by biological vectors, mainly insects. Reverse genetics using infectious clones—available for many plant viruses—has been used for identification of viral determinants involved in virus–host and virus–vector interactions. Although many studies have identified a number of factors involved in disease development and transmission, the precise mechanisms are unknown for most of the virus–plant–vector combinations. In most cases, the diverse outcomes resulting from virus–virus interactions are poorly understood. Although significant advances have been made towards understand the mechanisms involved in plant resistance to viruses, we are far from being able to apply this knowledge to protect cultivated plants from the all viral threats.The aim of this Special Issue was to provide a platform for researchers interested in plant virology to share their recent results. To achieve this, we invited the plant virology community to submit research articles, short communications and reviews related to the various aspects of plant virology: ecology, virus–plant host interactions, virus–vector interactions, virus–virus interactions, and control strategies. This issue contains some of the best current research in plant virology.
