This book answers the question “What is it that viruses do?” by presenting three aspects of viral ecology. The first aspect explains how viruses affect the population diversity and energetics of their host communities. Perhaps the most notable example of this concept is our understanding that primary production within ecosystems often depends upon those viruses which serve as controllers of nutrient recycling, connecting the aquatic and terrestrial realms in ways that can be assessed locally and globally. The second aspect describes genetic partnerships which exist between hosts and their viruses. These include processes termed endogeny and lysogeny by which the host carries at least a partial genomic copy of the virus. Fluidity of these collective genomes is expressed on an evolutionary time scale and the mutual life cycles which they produce represent a forging of shared genomic fate that obligates partnership of the virus and its host. The viral sequences represent a source of potential benefit as well as potential peril for the host and can implement phenotypic changes in the host. Hosts often use those changes as tools. As humans, the most notable example would be that mammals rely upon temporary activation of their endogenous viral genes in order to successfully develop a placenta. The third aspect is defending the health of a host, which relies upon activity in two directions. Hosts often use their captured viral genes to identify and subsequently direct battle against invading viruses. This natural concept has been engineered for combating cancer, is useful for suppressing the detrimental consequences of genetic diseases, and has been developed to create targeted antiviral vaccines. But, the defense has to work in two directions and the host can use other symbiotic microorganisms as protection against its viruses. This book will appeal to a wide readership by providing a broad perspective of viral ecology, and all scientists will find it helpful for gaining a view of fields beyond their specialization.

The current proliferation of scientific information makes it difficult for even the most diligent reader to keep up with the latest developments in his/her own field, let alone other areas of interest. Review articles are one solution, but they too have become so voluminous and detailed that they often defeat the purpose for which they were intended. We have attempted to ease this problem by using a different format. In this volume on Concepts in Viral Pathogenesis, we have assembled a series of mini-reviews/editorials, 1,000 to 2,000 words in length. Each is a pithy distil lation of the state-of-the-art with emphasis on current thinking and unifying concepts rather than a compendium of the literature. The 53 articles, all written by active workers in their respective fields, are organized systemati cally so that the book will provide busy investigators, teachers and students of up-to-date information in a very brief and easily read a conceptual core able form. In addition, the authors have attempted to identify unresolved problems and point to future directions.

The book emphasizes the emergence and reemergence of human viral diseases, the need for a global early warning system of surveillance, and the importance of continued research to develop preventative measures. Initial chapters provide a valuable perspective on the historical development of virology. The book presents the first account of the joint US-Russian effort to sequence smallpox virus DNA. "Concepts in Virology" focuses on critical areas of contemporary virology, including viral hepatitis, influenza, polio and emerging arthropod-borne viruses including yellow fever, rabies, cytomegalovirus, poxvirus, dengue and hemorrhagic fever with renal syndrome. In addition, the latest developments in antiviral drug therapy and vaccines for viral diseases (including AIDS) are discussed. Brian W. J.

Viral Ecology defines and explains the ecology of viruses by examining their interactions with their hosting species, including the types of transmission cycles that have evolved, encompassing principal and alternate hosts, vehicles, and vectors. It examines virology from an organismal biology approach, focusing on the concept that viral infections represent areas of overlap in the ecology of viruses, their hosts, and their vectors.

Corona- and related viruses are important human and animal pathogens that also serve as models for other viral-mediated diseases. Interest in these pathogens has grown tremendously since the First International Symposium was held at the Institute of Virology and Immunobiology of the University of Wiirzburg, Germany. The Sixth International Symposium was held in Quebec City from August 27 to September I, 1994, and provided further understanding of the molecular biology, immunology, and pathogenesis of corona-, toro-, and arterivirus infections. Lectures were given on the molecular biology, pathogenesis, immune responses, and development of vaccines. Studies on the pathogenesis of coronavirus infections have been focused mainly on murine coronavirus, and mouse hepatitis virus. Neurotropic strains ofMHV (e.g., JHM, A59) cause a demyelinating disease that has served as an animal model for human multiple sclerosis. Dr. Samuel Dales, of the University of Western Ontario, London, Canada, gave a state-of-the-art lecture on our current under standing of the pathogenesis of JHM-induced disease.

Astroviruses were first identified in the feces of children in 1975. Since then, they have been found in ~ 3 to 20% of children with diarrhea. Given that serological studies have demonstrated that up to 90% of children have been exposed to at least one strain of astrovirus by age 9, the prevalence of infection may be much higher. Supporting this are studies demonstrating that astroviruses can also be isolated in a subset of asymptomatic individuals, suggesting that a proportion of infected individuals shed the virus asymptomatically or for some time after the resolution of other symptoms of infection. Asymptomatic carriers may be a major reservoir for astroviruses in the environment and could contribute to dissemination of the virus. Astroviruses are extremely stable in the environment and can be transmitted nosocomially, directly from infected individuals and potentially animals, and through contaminated food and water. Although typically an acute disease, astrovirus infection in premature infants may be associated with the development of necrotizing enterocolitis and in new-onset celiac disease in children. Immunocompromised children are even more susceptible often developing persistent infections that lead to wasting or even systemic infections associated with fatal encephalitis. In spite of its importance, little is known about astrovirus pathogenesis, molecular biology, epidemiology, or cell biology. The goal of this book is to provide the latest and most up-to-date information on this medically important and rapidly evolving group of viruses. It will include sections on the history of astroviruses and their disease in humans; information on viral replication and immune responses; new information on how astroviruses induce disease including the expression of a viral enterotoxin regulating intestinal epithelial cell tight junctions, the isolation and identification of new astrovirus genotypes in mammals including humans, and astroviruses of veterinary importance. Finally, the book will also introduce the complexity of astrovirus epidemiology and potential as an important new zoonotic disease, and its role in food-borne disease. This will be the first book of its kind and will be of great interest to microbiologists, virologists, infectious disease specialists, immunologists, pediatricians, public health and food safety experts, veterinarians, poultry industry specialists, and researchers and clinicians interested in enteritis. ​

Milton Taylor, Indiana University, offers an easy-to-read and fascinating text describing the impact of viruses on human society. The book starts with an analysis of the profound effect that viral epidemics had on world history resulting in demographic upheavals by destroying total populations. It also provides a brief history of virology and immunology. Furthermore, the use of viruses for the treatment of cancer (viral oncolysis or virotherapy) and bacterial diseases (phage therapy) and as vectors in gene therapy is discussed in detail. Several chapters focus on viral diseases such as smallpox, influenza, polio, hepatitis and their control, as well as on HIV and AIDS and on some emerging viruses with an interesting story attached to their discovery or vaccine development. The book closes with a chapter on biological weapons. It will serve as an invaluable source of information for beginners in the field of virology as well as for experienced virologists, other academics, students, and readers without prior knowledge of virology or molecular biology.
