Virus Discovery by Metagenomics: The (Im)possibilities


Book Description

Since the late 1800s, the discovery of new viruses was a gradual process. Viruses were described one by one using a suite of techniques such as (electron) microscopy and viral culture. Investigators were usually interested in a disease state within an organism, and expeditions in viral ecology were rare. The advent of metagenomics using high-throughput sequencing has revolutionized not only the rate of virus discovery, but also the nature of the discoveries. For example, the viral ecology and etiology of many human diseases are being characterized, non-pathogenic viral commensals are ubiquitous, and the description of environmental viromes is making progress. This Frontiers in Virology Research Topic showcases how metagenomic and bioinformatic approaches have been combined to discover, classify and characterize novel viruses.

Infectious Diseases


Book Description

This volume on Infectious Diseases in an Encyclopedia of Sustainability Science and Technology (ESST) addresses the needs of health care providers and policy makers as well as scientists and engineers. Most of chapters in this volume deal with infectious diseases that directly affect humans, including the detailed characterization of specific pathogens, how they reproduce, how they are transmitted, and the means available to control, eliminate, or eradicate them. In this revised and updated second edition, the number of human infectious diseases covered has been significantly expanded. Other new chapters deal with current leading edge technologies for the diagnosis of pathogens; surveillance including environmental and syndromic surveillance for pathogens; requirements for quality assurance, quality control and the need for biological standards and controls to sustain high quality diagnosis and surveillance; the use of big data for personalized medicine; modeling infectious diseases; zoonotic and vector borne diseases; disease prevention with antibiotics, antivirals and vaccines; and factors that affect ecological balances leading to emergence of new diseases such as climate change and deforestation. Finally, infectious diseases that affect livestock and culture of plants for food, comfort and beauty are also addressed, since we must also consider them when discussing sustainability of humans in our ecosystem.




Geminivirus: Detection, Diagnosis and Management


Book Description

Geminivirus: Detection, Diagnosis and Management focuses on the latest techniques for managing diseases caused by these circular, single-stranded (ss) DNA genomes. The most significant impact of plant diseases in host populations is often caused by emerging diseases, whose incidence in a plant host is increasing as a result of long-term changes in their underlying epidemiology. Genetic changes in pathogen and host populations, as well as changes in host ecology and environment, are major factors contributing to disease emergence. Understanding plant virus evolution is crucial for modeling the within-host and between-host dynamics and genetics of virus populations. The book presents a comprehensive review of how these viruses develop, including contributing factors such as population bottlenecks during cell-to-cell movement, systemic colonization, or between-host transmission by different procedures. Presented in five sections—Detection and Diagnosis, Emergence and Diversity, Vector and Transmission, Virus–Host Interaction, and Disease Management, the book includes host range determinant and virulence factors involved in pathogenesis, virus–vector interactions during acquisition, retention, and transmission and evaluating management strategies to control Geminivirus. The book is an essential reference for students and researchers interested in plant virology, particularly begomoviruses, geminiviruses, and vector transmission biology. Introduces identification and characterization of geminiviruses that infect agricultural crops, their wild relatives, and weed hosts Discusses recombination and reassortment mechanisms influencing viral genetic diversity, virulence, and vector transmission Explores the origin, evolution, and bottlenecks of Geminiviruses Introduces identification and characterization of geminiviruses that infect agricultural crops, their wild relatives, and weed hosts Discusses recombination and reassortment mechanisms influencing viral genetic diversity, virulence, and vector transmission Explores the origin, evolution, and bottlenecks of Geminiviruses




Viral Metagenomics
