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.
This book describes the basic features of virus replication, and
points out how these features lead into the diverse biologies and
genetics of the various viruses.
This book reviews the early evidence of genetic variability of
rhabdoviruses. It describes data on the variability in the genomes
of closely related virus strains and the variability that can be
observed within a given virus strain.
This book analyzes the nature of polio replication complexes with
respect to subcellular fractionation, responses to detergent
treatments, and the viral/cellular proteins involved. It presents
models for both initiation and elongation of RNA chains by the
poliovirus replicase.

This volume brings together recent developments in quasispecies
theory extended to variable environments and practical applications
in elucidating viral dynamics and treatment designs. In particular,
the existence of an error threshold in rugged fitness landscapes
has opened the way to a new antiviral strategy termed lethal
mutagenesis, which is now under intensive theoretical, experimental
and clinical investigation. As such the book explains how an
understanding of quasispecies dynamics within infected organisms
has increased our knowledge of viral disease events. From a
clinical perspective, population dynamics highlights important
problems for viral disease control, such as the selection of
drug-resistant mutants that often accompanies treatment failures,
and suggests means of increasing the effectiveness of antiviral
treatments. The book is intended for students and scientists
interested in basic and applied aspects of biophysics, chemistry,
biology, evolution and medical virology.

Der vorliegende 48. Band der Reihe "Fortschritte der
Arzneimittelfor- schung" enthalt acht Beitrage, die wiederum von
anerkannten Forschern verfasst wurden. Ausserdem sind auch in
diesem Band ein Stichwortver- zeichnis des Bandes sowie ein
Autoren-und Titelverzeichnis und ein Titel- verzeichnis aller 48
Bande enthalten. Der Leser hat dadurch die Mog- lichkeit, nicht nur
den vorliegenden Band zu konsultieren, sondern auch alle bisher
erschienenen Bande quasi als enzyklopadisches N achschla- gewerk zu
benutzen. Da alle Beitrage umfangreiche Literaturnachweise
enthalten, ist die Moglichkeit des Zugriffes auf
Original-Publikationen gegeben, was dem aktiven Forscher besonders
wichtig ist und seinen eige- nen Arbeiten Impulse geben kann. Die
Artikel des 48. Bandes behandeln neue Entwicklungen der Genetik,
der enzymatischen Herstellung von komplexen Peptiden und bringen
die neuesten Erkenntnisse der Apoptose unserem Verstandnis naher.
Immun- therapie bei Hirnerkrankungen und psychischen Storungen, der
Einsatz vonNaturproduktenzur Vorbeugung von Krebserkrankungen, das
beun- ruhigende Anwachsen der Arzneimittelresistenz, die
Mannigfaltigkeit der Dopamin-Rezeptor-Wirkung und die faszinierende
Darstellung einer grosseren Gruppe von neuartigen Nukleosiden als
Arzneimittel runden den vorliegenden Band der "Fortschritte der
Arzneimittelforschung" ab und bieten dem Leser viel Neuartiges und
Interessantes.
Progress in Drug Research is a prestigious book series which
provides extensive expert-written reviews on a wide spectrum of
highly topical areas in current pharmaceutical and pharmacological
research. It serves as an important source of information for
researchers concerned with drug research and all those who need to
keep abreast of the many recent developments in the quest for new
and better medicines.
Continuous genetic variation and selection of virus subpopulations
in the course of RNA virus replications are intimately related to
viral disease mechanisms. The central topics of this volume are the
origins of the quasispecies concept, and the implications of
quasispecies dynamics for viral populations.

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 provides both the basic foundations
for the evolutionary dynamics of viruses and specific examples of
emerging diseases explained by the evolutionary flexibility of the
viral agents that circulate in a continuously changing earth
environment.
* NEW to this edition - chapters on the molecular basis of copying
fidelity of viral polymerases, methods to establish phylogenetic
relationships among viruses, and the mechanisms of cellular RNA
interference and editing functions as they affect virus evolution.
* UNIQUE - combines theoretical concepts in evolution with detailed
analyses of the evolution of important virus groups.
* Bacterial, plant, animal and human viruses are compared regarding
their interaction with their hosts.
