Highly Mutable Animal RNA Viruses: Adaptation and Evolution by Anonim Pdf

Viruses are widely present in nature, and numerous viral species with a variety of unique characteristics have been identified so far. Even now, new emerging or re-emerging viruses are being found or re-found as novel viral classes or as quasi-species. Indeed, viruses are everywhere. Of note, viruses are pivotal as targets and tools of basic and applied sciences. On one hand, portions of the viruses are infectious for animals including humans, and cause various diseases in infected hosts by distinct mechanisms and at a different level of severity. While many of viruses are known to co-exist quietly with their hosts, pathogenic viruses certainly affect and threaten our society as well as individuals to provoke serious medical or economic attention. We should act against certain dreadful and highly infectious viruses as a global problem. Animal RNA viruses can readily mutate to adapt themselves in their hostile environments for their survival. Resultant viruses may sometimes show essentially altered phenotypes from the original parental strains. This fundamental and general property of animal RNA viruses represents major extensive issues of scientific, medical, and/or economic importance. In this Research Topic, we have focused on the high mutability of animal RNA viruses, and selected relevant articles on animal viruses of broad-ranges such as primate lentiviruses, influenza viruses, paramyxoviruses, flaviviruses, rabies virus, norovirus, picornaviruses, and picobirnavirus. Each article has taken up intriguing aspects of the subject viruses. We are sure that readers acquire important information on virus mutation, adaptation, diversification, and evolution, and hope that researchers in the field related to virology gain some solid hints from the reported articles for further virological and /or medical studies. Finally, we thank all the contributing researchers in this Research Topic, entitled "Highly Mutable Animal RNA Viruses: Adaptation and Evolution", for their elegant and interesting works.

Viral Fitness and Evolution by Esteban Domingo,Peter Schuster,Santiago F. Elena,Celia Perales Pdf

This book unifies general concepts of plant and animal virus evolution and covers a broad range of topics related to theoretical and experimental aspects of virus population dynamics and viral fitness. Timely topics such as viral mechanisms to cope with antiviral agents, the adaptability of the virus to new hosts, emergence of new viral phenotypes, and the connections between short- and long-term virus evolution are included. By comparing plant and animal viruses, universal mechanisms responsible for fitness variations, viral emergence and disease mechanisms are explored. Although emphasis is put on specific plant and human viral pathogens, relevant similarities and differences to other viruses are highlighted. Additionally, readers will learn more about the adaptability of coronaviruses, including the recently emerged SARS-CoV-2, the causative agent of the COVID-19 pandemic. The book is aimed at students and scientists interested in basic and applied aspects of plant and animal virus population dynamics and evolution.

Embracing Randomness by Katarina Marie Braun Pdf

Pathogenic RNA viruses emerging from zoonotic reservoirs are among the highest threats for global infectious disease control. Every single major epidemic or pandemic in the 21st century has resulted from an emerging or re-emerging zoonotic RNA virus. Severe Acute Respiratory Syndrome virus 1 (SARS-CoV) emerged in 2003, a novel pandemic H1N1 influenza virus in 2009, Middle East Respiratory Syndrome virus (MERS-CoV) in 2012 and 2015, Ebola in 2014, Zika virus in 2015, Yellow fever virus in 2016, and SARS-CoV-2 in 2019. It is clear the primary drivers of the emergence of these zoonotic RNA viruses are increasing globalization, habitat fragmentation, and encroachment of a continuously growing human population into wildlife habitats 1. It is notable that this increased interaction between humans and animals likely increases the risk of interspecies transmission among a large number of potential pathogens, yet RNA viruses are the dominant source of emerging human pathogens 2. The capacity for RNA viruses to rapidly adapt to new host environments and to respond to shifting selective pressures is not completely understood. Current dogma suggests this trait is tied to short generation times and high mutation rates resulting from error-prone viral replication. RNA virus mutability creates diverse viral populations which are more capable than homogenous populations of adapting to new hosts and host environments 3. However, the generation of viral variation is only the first step. Individual mutations that confer fitness benefits in particular environments must then increase in frequency and/or make their way out of individual hosts and into populations. This stage presents several obstacles that the virus must overcome and is therefore likely to be rate-limiting for the overall pace of viral evolution and host-switching. The first three chapters (chapters 2-4) of this dissertation focus on investigating the evolutionary processes by which zoonotic RNA viruses adapt to mammalian hosts. The results of this work call attention to several significant obstacles that zoonotic RNA viruses must overcome in order to successfully and efficiently emerge in and adapt to human hosts. I suggest these obstacles all derive from the effects of randomness on viral systems. The cumulative impact of these obstacles has critical implications in assessing the pandemic potential of viruses that have already caused human epidemics, like avian influenza viruses, and the adaptive potential of the current pandemic virus, SARS-CoV-2. The final two chapters (chapters 5-6) of this dissertation discuss our work combining principles of viral evolution with epidemiology and population health to investigate the early patterns of SARS-CoV-2 spread in the state of Wisconsin. Taken together, this work suggests the effects of randomness on viral populations within and between individual hosts are a previously underappreciated brake to the pace of viral adaptation and host-switching for influenza A virus (IAV) and SARS-CoV-2. Additionally, this work underscores the value of genomic epidemiology early in a pandemic to understand patterns of viral transmission in different populations and to assess the impact of public health guidelines and interventions on a rolling basis.

Virus as Populations by Esteban Domingo Pdf

Virus as Composition, Complexity, Quasispecies, Dynamics, and Biological Implications, Second Edition, explains the fundamental concepts surrounding viruses as complex populations during replication in infected hosts. Fundamental phenomena in virus behavior, such as adaptation to changing environments, capacity to produce disease, and the probability to be transmitted or respond to treatment all depend on virus population numbers. Concepts such as quasispecies dynamics, mutations rates, viral fitness, the effect of bottleneck events, population numbers in virus transmission and disease emergence, and new antiviral strategies are included. The book's main concepts are framed by recent observations on general virus diversity derived from metagenomic studies and current views on the origin and role of viruses in the evolution of the biosphere. Features current views on key steps in the origin of life and origins of viruses Includes examples relating ancestral features of viruses with their current adaptive capacity Explains complex phenomena in an organized and coherent fashion that is easy to comprehend and enjoyable to read Considers quasispecies as a framework to understand virus adaptability and disease processes

Emerging and Transboundary Animal Viruses by Yashpal Singh Malik,Raj Kumar Singh,Mahendra Pal Yadav Pdf

This book, which is the first volume of the book series-Livestock Diseases and Management, summarizes the prominence and implications of the emerging and transboundary animal viruses. Although the livestock plays an important role in the economy of many countries, the emerging and transboundary animal viral diseases possess a serious risk to the animal-agriculture sector and food security globally. The book describes the precise and up-to-date information on animal viral diseases which have emerged in the recent past or are re-emerging due to various environmental factors and those which are not bounded in restricted national boundaries and attained the transboundary status. The chapters summarize the recent advancements in the molecular state-of-art tools towards the development of diagnostics, prophylactics, and therapeutics of these viruses. It also explicitly describes the challenges imposed by the emerging and transboundary viral infections and our preparedness to counter them.

Viruses: Essential Agents of Life by Günther Witzany Pdf

A renaissance of virus research is taking centre stage in biology. Empirical data from the last decade indicate the important roles of viruses, both in the evolution of all life and as symbionts of host organisms. There is increasing evidence that all cellular life is colonized by exogenous and/or endogenous viruses in a non-lytic but persistent lifestyle. Viruses and viral parts form the most numerous genetic matter on this planet.
