Pseudomonas comprises three volumes covering the biology of pseudomonads in a wide context, including the niches they inhabit, the taxonomic relations among members of this group, the molecular biology of gene expression in different niches and under different environmental conditions, the analysis of virulence traits in plants, animals and human pathogens as well as the determinants that make some strains useful for biotechnological applications and promotion of plant growth. There has been growing interest in pseudomonads and a particular urge to understand the biology underlying the complex metabolism of these ubiquitous microbes. These bacteria are capable of colonizing a wide range of niches, including the soil, the plant rhizosphere and phylosphere, and animal tissues; more recently they have attracted attention because of their capacity to form biofilms, a characteristic with potentially important medical and environmental implications. The three volumes cover the following topics: - Taxonomy, - Genomics, - Life styles, - Cell Architecture, - Virulence, - Regulation, - Macromolecules, - Alternative Respiratory Substrates, - Catabolism and Biotransformations. Pseudomonas will be of use to all researchers working on these bacteria, particularly those studying microbiology, plant crops, pathogenesis, and chemical engineering. Advanced students in biology, medicine and agronomy will also find these three volumes a valuable reference during their studies.

One of the most exciting developments in the field of bacterial pathogenesis in recent years is the discovery that many pathogens utilize complex nanomachines to deliver bacterially encoded effector proteins into eukaryotic and prokaryotic target cells to modulate a variety of cellular functions for the pathogen’s benefit. These protein-delivery machines include the type III secretion system (T3SS), which is widespread in nature and encoded not only by bacteria pathogenic to vertebrates or plants, but also by bacteria that are symbiotic to plants or insects. Because they are essential virulence factors for many important human pathogens, these systems are emerging as a prime target for the development of new-generation, anti-infective drugs. This book reviews our current understanding of these intriguing injection machines as well as of the closely related T3SS that serves in flagella assembly. Individual chapters focus on regulation, assembly, structure, and function of the type III secretion machine and on the evolution of the secreted effector proteins. Given its scope, this book will appeal to a broad readership, including researchers and teachers in the fields of infectious diseases, host pathogen interactions, plant and animal pathogenesis, and symbiosis.

A Best Book of the YearSeed Magazine • Granta Magazine • The Plain-DealerIn this fascinating and utterly engaging book, Carl Zimmer traces E. coli's pivotal role in the history of biology, from the discovery of DNA to the latest advances in biotechnology. He reveals the many surprising and alarming parallels between E. coli's life and our own. And he describes how E. coli changes in real time, revealing billions of years of history encoded within its genome. E. coli is also the most engineered species on Earth, and as scientists retool this microbe to produce life-saving drugs and clean fuel, they are discovering just how far the definition of life can be stretched.

Encyclopedia of Microbiology, Fourth Edition, Five Volume Set gathers both basic and applied dimensions in this dynamic field that includes virtually all environments on Earth. This range attracts a growing number of cross-disciplinary studies, which the encyclopedia makes available to readers from diverse educational backgrounds. The new edition builds on the solid foundation established in earlier versions, adding new material that reflects recent advances in the field. New focus areas include `Animal and Plant Microbiomes’ and ‘Global Impact of Microbes`. The thematic organization of the work allows users to focus on specific areas, e.g., for didactical purposes, while also browsing for topics in different areas. Offers an up-to-date and authoritative resource that covers the entire field of microbiology, from basic principles, to applied technologies Provides an organic overview that is useful to academic teachers and scientists from different backgrounds Includes chapters that are enriched with figures and graphs, and that can be easily consulted in isolation to find fundamental definitions and concepts

This publication looks at prawns and shrimps of the world, their ecology and consumption. It goes on to look at their physiology and feed as well as the technical aspects of prawn fishing.

We live in a well-engineered universe. This engineering is present in every system and organism in existence, including in the actions and interactions of plants and animals. In fact, one could say that the function and movement of plants and animals is just as much a part of their makeup as chlorophyll and fiber or bone and blood. Consequently, if we want to understand the ecology of animals and plants especially in an integrated ecosystem, it follows that great insight can be gained by taking an approach that studies function and integration of parts rather than the individual parts themselves. Ecology and Biomechanics: A Mechanical Approach to the Ecology of Animals and Plants offers a collection of state-of-the-art papers that ingeniously demonstrates how biomechanics can provide novel insights into long standing ecological and evolutionary questions. The majority of the book's chapters were originally presented at a symposium held at the annual meeting of the Society for Experimental Biology in Edinburgh, U.K., in 2004. Combining approaches from various disciplines, this volume covers subjects that encompass theoretical concepts and practical approaches involving research on both plants and animals, as well as interactions between the two. Although most of the examples emphasize distinct organism-environment relationships such as the grazing of ruminants, the book also includes a few examples that span larger temporal and spatial scales, achieving wider application across ecosystems. This can be seen in the chapter Implications of Microbial Motility on the Water Column Ecosystems, which highlights how microbial ecosystems can be understood from the mechanics, morphology, and motile responses of the individual organisms. Designed to serve as a reference for students and researchers, Ecology and Biomechanics: A Mechanical Approach to the Ecology of Animals and Plants paves the way for further research by demonstrating what can happen when the approaches from two seemingly disparate subdisciplines within the field of biology are creatively combined.

The bacterial flagellum is a supramolecular motility machinery consisting of the basal body acting as a rotary motor, the hook as a universal joint and the filament as a helical propeller. The bacterial flagellar motor composed of a rotor ring and a dozen stators is powered by an electrochemical-potential difference of specific ions across the cytoplasmic membrane and rotates in either the counterclockwise (CCW) or clockwise (CW) direction. A sensory signal transduction pathway regulates the switching between the CCW and CW states of the motor in response to environmental stimuli, allowing bacterial cells to migrate more desirable environments for their survival. The core structure of the bacterial flagellum is conserved among bacterial species. However, recent structural analyses of intact flagellar structures derived from various bacterial species by electron cryotomography and subtomogram averaging have shown that novel and divergent structures surround the core structure, suggesting that the flagellar motors have adapted to function in various environments of the habitat of bacteria. This Special Issue of Biomolecules covers recent advances in our understanding of and perspectives on the flagellar motor derived from different bacterial species.
