This stunningly illustrated book provides a rare window into the amazing, varied, and often beautiful world of viruses. Contrary to popular belief, not all viruses are bad for you. In fact, several are beneficial to their hosts, and many are crucial to the health of our planet. Virus offers an unprecedented look at 101 incredible microbes that infect all branches of life on Earth--from humans and other animals to insects, plants, fungi, and bacteria.Featuring hundreds of breathtaking color images throughout, this guide begins with a lively and informative introduction to virology. Here readers can learn about the history of this unique science, how viruses are named, how their genes work, how they copy and package themselves, how they interact with their hosts, how immune systems counteract viruses, and how viruses travel from host to host. The concise entries that follow highlight important or interesting facts about each virus. Learn about the geographic origins of dengue and why old tires and unused pots help the virus to spread. Read about Ebola, Zika, West Nile, Frog virus 3, the Tulip breaking virus, and many others--how they were discovered, what their hosts are, how they are transmitted, whether or not there is a vaccine, and much more. Each entry is easy to read and includes a graphic of the virus, and nearly every entry features a colorized image of the virus as seen through the microscope.Written by a leading authority, this handsomely illustrated guide reveals the unseen wonders of the microbial world. It will give you an entirely new appreciation for viruses.

A comprehensive and richly illustrated introduction to the world of virusesAs parasites that are often hundreds of times smaller than bacteria, viruses exist in and on everything, everywhere. Rapidly evolving, they are highly opportunistic and relentlessly efficient. While some viruses are obviously agents of disease, as the COVID-19 pandemic has reminded the world only too well, others can be beneficial, helping to protect their hosts from other microbes, or allowing hosts to function in otherwise impossible ways. In Viruses, virus expert and author Marilyn Roossinck presents a comprehensive and richly illustrated introduction to viruses that reveals their true nature.Using lively text, clear graphics, and beautiful imagery, Viruses examines all the aspects of viruses that are essential for understanding them--their diversity, behaviors, life cycles, and much more. Written in a nontechnical and easy-to-follow style, the book covers what viruses are and where they come from; how they transmit and evolve; the battle between viruses and hosts, including immunity and vaccination; viruses that are good for us; the critical role viruses play in the balance of earth's ecosystems; what makes a virus--including COVID-19 and influenza--become pandemic in plants or animals; and the cutting-edge research that is discovering thousands of new viruses. Each chapter concludes with stunningly illustrated profiles that highlight key viruses.In a world where comprehending viruses is more important than ever, Viruses offers a rich and inviting introduction to organisms that, for all the harm they can do, are also essential for the health of animals, plants, and the world we share.

Einblicke in einer verborgene Welt Viren sind Grenzgänger des Lebens. Mikroskopisch klein, als Krankheitserreger gefürchtet, doch in ihrer Vielfalt und in ihrer Bedeutung für die biologischen Netzwerke auf der Erde und für die Evolution des Lebens erst ansatzweise verstanden - und immer wieder für Überraschungen gut. Viren sind Opportunisten, die oft geduldig auf ihre Chance warten - in Ruhestadien oder eingebettet in das Erbgut ihrer Wirte -, und Meister der Anpassung. Ihre Vermehrungsstrategien und Übertragungsmechanismen sind so vielfältig wie ihre Erscheinungsformen. Die meisten Viren sind "nur" Nucleinsäuren in einer Proteinhülle, aber sie kapern Pflanzen-, Tier- und Bakterienzellen, nisten sich dort langfristig ein oder übernehmen unmittelbar die genetische Kontrolle. Dieser Band eröffnet einen faszinierenden Blick auf das ganze Panorama dieser Lebenskünstler, die wir gewöhnlich als Feinde betrachten, die aber auch Helfer sein können. Nach einer Einführung in die Grundlagen der Virologie - was genau sind Viren, woraus bestehen sie, wie sehen ihre Lebenszyklen aus, welche Evolutionspfade haben sie beschritten? - liefern 101 Porträts detaillierte Einblicke in die besonderen Eigenschaften und Fähigkeiten einzelner Virustypen, vom Grippeerreger bis zum Bakteriophagen T4, vom Tabakmosaikvirus bis zu den gefürchteten Ebola-, Zika- und Dengue-Viren.

* Una introducción completa y ampliamente ilustrada al mundo de los virus, que nos revela su verdadera naturaleza.* Los virus, parásitos que a menudo son cientos de veces más pequeños que las bacterias, están presentes en todas partes. Evolucionan con rapidez, son muy oportunistas e implacablemente eficaces. * Con un texto dinámico, gráficos claros y hermosas imágenes, este libro examina todos los aspectos esenciales para su diversidad, comportamiento, ciclo vital y mucho más.Aunque algunos virus son obviamente agentes de enfermedades, como le ha recordado demasiado bien al mundo la pandemia de COVID-19, otros pueden ser beneficiosos y ayudar a proteger a sus huéspedes de otros microbios, o les permiten funcionar de maneras que de otro modo serían imposibles.Escrito en un estilo no técnico y fácil de seguir, el libro abarca qué son los virus y de dónde proceden; cómo se transmiten y evolucionan; la batalla entre ellos y sus huéspedes, incluidas la inmunidad y la vacunación; los virus que son buenos para nosotros; el papel fundamental que desempeñan en el equilibrio de los ecosistemas terrestres; qué hace que un virus —como el del COVID-19 y la gripe— se convierta en pandémico en plantas o animales; y la investigación de vanguardia que descubre miles de virus nuevos. Cada capítulo concluye con perfiles ilustrados que destacan virus clave.
