Mter the discoveryof the tobacco mosaic virus by D. I. Ivanov skU in 1892 [14], the new science of virology was born and began to develop rapidly. The number of viruses now known is enormous and they can infect nearly all animal and plant organisms. Microorganisms themselves are no exception to this rule. Despite intensive study of Vlruses, their origin and nature are still a subject for speculation and hypothesis. The general concept of viruses embraces a wide group of biologically active structures occupying an intermediate position between living and nonliving matter. The dual character of viruses is determined by the fact that, while they do not possess an inde pendent system of metabolism, which is a characteristic feature of every living being, they nevertheless carry within themselves all the necessary information for autoreproduction. A striking feature of the virus is that it consists essentially of two components: a protein envelope and the nucleic acid con tained within it. In contrast to the elementary structural unit of the living or ganism, the cell, which contains two types of nucleic acid (DNA and RNA), the virus particle contains only one type of nucleic acid - either DNA or RNA. It is perhaps this which is responsible for the imperfection of the virus as a living organism.

How a mysterious, super-powerful—yet long-neglected—microbe rules our world and can rescue our health in the age of antibiotic resistance. At every moment, within our bodies and all around us, trillions of microscopic combatants are waging a war that shapes our health and life on Earth. Countless times per second, viruses known as phages attack and destroy bacteria while leaving all other life forms, including us, unscathed. Vastly outnumbering the viruses that do us harm, phages power ecosystems, drive evolutionary innovation, and harbor a remarkable capacity to heal life-threatening infections when conventional antibiotics fail. Yet most of us have never heard of them, thinking of viruses only as enemies to be feared. The Good Virus prompts us to reconsider, and to discover, how these viruses could save countless lives if we can learn to harness their extraordinary abilities. Taking us inside the ongoing quest to use phages’ powers for good, Tom Ireland introduces us to the brilliant, often eccentric, scientists who have fought to realize phages’ potential in the face of doubt and political intrigue. We meet the renegade French-Canadian scientist who discovered phages and pioneered their use as medicine over a century ago, leading them to be hailed as the world’s first genuine antibiotic years before penicillin. We learn why, in some pockets of the former Soviet Union, drinking a vial of phages remains as common as taking an over-the-counter drug. We follow the intrepid scientists and doctors now racing to make “phage therapy” work worldwide as the threat of antibiotic-resistant bacteria grows ever more urgent—even as other researchers uncover how phages bolster our everyday immunity, help generate the oxygen we breathe, and furnish the origins for breakthrough technologies like CRISPR. Unveiling the hidden rulers of the microbial world and celebrating the surprising power of viruses to heal, not harm, The Good Virus forever changes how we see nature’s most maligned life forms.

In 1965, French microbiologist André Lwoff was awarded the Nobel Prize in Physiology or Medicine for his work on lysogeny—one of the two types of viral life cycles—which resolved a contentious debate among scientists about the nature of viruses. A Tale of Two Viruses is the first study of medical virology to compare the history of two groups of medically important viruses—bacteriophages, which infect bacteria, and sarcoma agents, which cause cancer—and the importance of Lwoff’s discovery to our modern understanding of what a virus is. Although these two groups of viruses may at first glance appear to have little in common, they share uniquely parallel histories. The lysogenic cycle, unlike the lytic, enables viruses to replicate in the host cell without destroying it and to remain dormant in a cell’s genetic material indefinitely, or until induced by UV radiation. But until Lwoff’s discovery of the mechanism of lysogeny, microbiologist Félix d’Herelle and pathologist Peyton Rous, who themselves first discovered and argued for the viral identity of bacteriophages and certain types of cancer, respectively, faced opposition from contemporary researchers who would not accept their findings. By following the research trajectories of the two virus groups, Sankaran takes a novel approach to the history of the development of the field of medical virology, considering both the flux in scientific concepts over time and the broader scientific landscapes or styles that shaped those ideas and practices.

It is hardly necessary to define the concept of receptors to readers of this series, but it should be born in mind that in several instances receptors are undefined entities, whose molecular details remain to be established. On the other hand the ligand, which reco~izes the receptors, has been identified and characterized in most cases. The current interest in the structure and function of biological membranes gives great expectations that in the near future we may understand the details of ligand-receptor interaction. This interaction involves two defined steps: the first, usually referred to as recognition, is followed by the second step, transduction, in which the ligand-receptor interaction is translated by the cell into a biochemical action. The present two volumes which cover prokaryotic and eukaryotic virus receptors, have been published together in order to illustrate the specificity of virus receptor recognition which appears to be a guiding principle for both bacteria and higher cells. The identification and characterization of the receptors for phages of gram-negative bacteria has to a large extent relied on the genetic techniques available for these organisms. In a similar way the availability of genetic systems has also clarified the interrelationship between animal retrovirus receptors even if the molecular structure remains to be determined. The paucity of defined genetic systems may therefore explain part of our ignorance concerning the molecular details of virus receptors on human cells and possibly also on gram positive bacteria.

The Viruses: Biochemical, Biological, and Biophysical Properties, Volume 2: Plant and Bacterial Viruses deals with the biochemistry, biology, and biophysics of plant viruses. The viruses considered are tobacco and turnip yellow mosaic viruses; tobacco ringspot virus; potato virus X; and bacterial viruses, such as lysogenic bacteria and phages. This volume is organized into 10 chapters and begins with a discussion of the tobacco mosaic virus and other plant viruses, emphasizing the process of infection and synthesis and general features of the host-virus system. The next chapters focus on the purification and protein components of plant viruses; the chemical correlates of biological variability in viruses; and biological cycles of plant viruses in insect vectors. This book describes the bacteriophage, which is considered as a model virus in comparison with typical microorganisms and cellular organelles. It also introduces the reader to the kinetics of phage reproduction; the intracellular multiplication of bacterial viruses; and the process of lysogeny in bacteria. The book concludes with a chapter on irradiation of phage with ultraviolet light, decay of incorporated radiophosphorus (""suicide""), and ionizing radiation (usually X-rays). Biologists, botanists, biochemists, biophysicists, and microbial physiologists will find this book a rich source of information on plant and bacterial viruses.

Bacteriophages, or phages, are viruses that infect bacteria and are believed to be the most abundant and genetically diverse organisms on Earth. As such, their ecology is vast both in quantitative and qualitative terms. Their abundance makes an understanding of phage ecology increasingly relevant to bacterial ecosystem ecology, bacterial genomics and bacterial pathology. Abedon provides the first text on phage ecology for almost 20 years. Written by leading experts, synthesizing the three key approaches to studying phage ecology, namely studying them in natural environments (in situ), experimentally in the lab, or theoretically using mathematical or computer models. With strong emphasis on microbial population biology and distilling cutting-edge research into basic principles, this book will complement other currently available volumes. It will therefore serve as an essential resource for graduate students and researchers, particularly those with an interest in phage ecology and evolutionary biology.
