Arenaviruses I

Download or read book Arenaviruses I written by M.B.A. Oldstone and published by Springer Science & Business Media. This book was released on 2013-03-07 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the subject of arenaviruses was visited by Current Topics in Microbiology and Immunology 14 years ago, enormous advances have been made in this area. The receptor for several arenaviruses, alpha-dystroglycan, was identified, the replication strategy of these viruses was decoded, and application of a reverse genetics system for studying viral gene function and viral biology is well underway. In addition to reviewing these advances, Volume I includes discussion of arenaviral molecular phylogeny, reservoirs in rodents and clinical diseases caused by both new world and old world arenaviruses.

Download or read book Fenner and White's Medical Virology written by Christopher J. Burrell and published by Academic Press. This book was released on 2016-11-09 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fenner and White's Medical Virology, Fifth Edition provides an integrated view of related sciences, from cell biology, to medical epidemiology and human social behavior. The perspective represented by this book, that of medical virology as an infectious disease science, is meant to provide a starting point, an anchor, for those who must relate the subject to clinical practice, public health practice, scholarly research, and other endeavors. The book presents detailed exposition on the properties of viruses, how viruses replicate, and how viruses cause disease. These chapters are then followed by an overview of the principles of diagnosis, epidemiology, and how virus infections can be controlled. The first section concludes with a discussion on emergence and attempts to predict the next major public health challenges. These form a guide for delving into the specific diseases of interest to the reader as described in Part II. This lucid and concise, yet comprehensive, text is admirably suited to the needs of not only advanced students of science and medicine, but also postgraduate students, teachers, and research workers in all areas of virology. - Features updated and expanded coverage of pathogenesis and immunity - Contains the latest laboratory diagnostic methods - Provides insights into clinical features of human viral disease, vaccines, chemotherapy, epidemiology, and control

Available in PDF, EPUB and Kindle. Book excerpt: also occurs. New outbreaks of yellow fever have occurred in Colombia and Trinidad and new outbreaks of rift valley fever have occurred in Egypt. Chapter 6, Arenaviruses: The biochemical and physical properties have now been clar ified, and they show a remarkable uniformity in the various viruses constituting the group. The possibility that prenatal infection with LCM may result in hydrocephalus and chorioretinitis has been raised. Serologic surveys have suggested the existence of Lassa virus infection in Guinea, Central African Empire, Mali, Senegal, Cameroon, and Benin, in addition to earlier identification in Nigeria, Liberia, and Sierra Leone. Chapter 7, Coronaviruses: New studies have confirmed the important role of these viruses in common respiratory illnesses of children and adults. The viruses are now known to contain a single positive strand of RNA. About 50% of corona virus infections result in clinical illness. About 5% of common colds are caused by strain DC 43 in winter. Chapter 8, Cytomegalovirus: Sections on pathogenesis of CMV in relation to organ transplantation and mononucleosis, as well as sections on the risk and features of con genital infection and disease, have been expanded. There are encouraging preliminary results with a live CMV vaccine, but the questions of viral persistence and oncogenicity require further evaluation.

Download or read book Activation of Viruses by Host Proteases written by Eva Böttcher-Friebertshäuser and published by Springer. This book was released on 2018-05-22 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will give an overview on viruses undergoing proteolytic activation through host proteases. The chapters will be organized in three themed parts, the first part describing respective viruses and their characteristics in detail. In the second part the molecular and cellular biology of the proteases involved as well as their physiological functions will be further explored. The third part will contain a chapter on protease inhibitors that are promising tools for antiviral therapy. This book will engage scholars in virology and medical microbiology as well as researchers with an interest in enzymology and protein structure and function relationship.

Available in PDF, EPUB and Kindle. Book excerpt: M. B. A. OLDSTONE Viruses are generally studied either because they cause significant human, animal or plant disease or for their utility as materials to probe a basic phenomenon in biology, chemistry, genetics or molecular biology. Arenaviruses are unusually interesting in that they occupy both of these categories. Arenaviruses cause severe human diseases known primarily as the hemor rhagic fevers occurring in South and Latin America (Bolivia: Machupo virus and Argentina: Junin virus) and in Africa (Lassa virus). Because such viruses produce profound disability and may kill the persons they infect, they are a source of economic hardship in the countries where they are prevalent. Further, they provide new problems for health care personnel owing to the narrowing of the world as visitors from many countries increasingly travel to and from these endemic areas. In addition, lymphocytic choriomeningitis virus (LCMV) can infect humans worldwide, although the illness is most often less disabling than those elicited by other arenaviruses. Yet LCMV is likely of greater concern to non-arena-virologists and experimentalists using tissue culture or animals, i. e. , workers in molecular biology, cancer research, virology, immunobiology, etc. , because normal appearing cultured cells or tissues and animals used for research may be persistently infected with LCMV without manifesting clinical disease or cytopathology and transmit that infection to laboratory workers (reviewed OLDSTONE and PETERS 1978). For example, HINMAN et al.

Download or read book Hemorrhagic Fever Viruses written by Maria S. Salvato and published by Humana Press. This book was released on 2017-10-07 with total page 425 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents protocols that analyze and explore hemorrhagic fever viruses (HFV). This book is divided into 5 parts: Part I begins with an overview on predicting viral pandemics and then covers methods for surveillance, diagnosis, and classification of HFV. This includes an antibody capture method using Lassa virus antigens. Part II discusses structural studies and reverse genetics of HFV. The chapters in this part describe envelope glycoprotein membrane fusion studies, arenavirus nucleocapsid protein, and the use of virus-like-particles to study viral egress. Part III explores in vivo models of HFV infections, and contains chapters on murine, guinea pig, and primate models for HFV, and methods to obtain a subset of primary human liver cells that can be cultured long-term. Part IV looks into immune assays and vaccine production for HFV. The chapters in this section cover the attenuated vaccine for Argentine HFV, detecting virus-antibody immune complexes in secondary dengue infections, and DNA vaccination. Part V discusses host responses to viral hemorrhagic fever, and contains chapters on identifying host restrictions to Junín or Dengue infection, and a cell-culture method to assess coagulation after HFV infection. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Thorough and cutting-edge, Hemorrhagic Fever Viruses: Methods and Protocols is a valuable resource for scientists and researchers who want to bridge the gap between virus recognition in surveillance and understanding host responses to infection.
