Book Description
Studies of the bacterial cell wall emerged as a new field of research in the early 1950s, and has flourished in a multitude of directions. This excellent book provides an integrated collection of contributions forming a fundamental reference for researchers and of general use to teachers, advanced students in the life sciences, and all scientists in bacterial cell wall research. Chapters include topics such as: Peptidoglycan, an essential constituent of bacterial endospores; Teichoic and teichuronic acids, lipoteichoic acids, lipoglycans, neural complex polysaccharides and several specialized proteins are frequently unique wall-associated components of Gram-positive bacteria; Bacterial cells evolving signal transduction pathways; Underlying mechanisms of bacterial resistance to antibiotics.

Book Description
This book examines specific techniques which can be used to explore new drug targets and the effectiveness of new antibiotics. By testing new antimicrobial agents and modified existing drugs, the most vulnerable cell processes, such as cell wall and membrane synthesis, DNA replication, RNA transcription and protein synthesis, can be better exploited. This in-depth volume, however, delves even deeper by identifying additional novel cellular targets for these new therapies. The book will provide laboratory investigators with the vital tools they need to test the antimicrobial potential of products and to curb the rise of so many infectious diseases.

Book Description
More than seventy years after Fleming's discovery of lysozyme, this enzyme continues to play a crucial role as a model enzyme in protein chemistry, enzymology, crystallography, molecular biology and genetics, immunology and also in evolutionary biology. The classical representative of this widespread enzyme family is the hen egg-white lysozyme. Chicken (c)-type lysozymes have also been characterized in many other animals including mammals, reptiles and invertebrates. Besides this c-type lysozyme, other distinct types, differing on the basis of structural, catalytic and immunological critera, have been described as well, these in birds, phages, bacteria, fungi, invertebrates and plants. The specificity, however, of all these enzymes is the same: they cleave a ß-glycosidic bond between the C-1 of N-acetylmuramic acid and the C-4 of N-acetylglucosamine of the bacterial peptidoglycan. In this volume special emphasis is placed on results obtained during the last ten years. Lysozymes are by no means merely defence or, in certain cases, digestion enzymes. In fact, peptidoglycan fragments released by the lytic action of this enzyme family can trigger the synthesis of immunostimulating or antibacterial substances, and a host of other unexpected, biological reactions may be provoked by lysozymes as well. As Fleming has prophesized: ''We shall hear more about lysozyme''.

Book Description
As a reflection of the quantum leap that has been made in the study of glycostructures, the first edition of this book has been completely revised and updated. The editors give up-to-date information on glycostructures, their chemistry and chemical biology in the form of a completely comprehensive survey. Glycostructures play highly diverse and crucial roles in a myriad of organisms and important systems in biology, physiology, medicine, bioengineering and technology. Only in recent years have the tools been developed to partly understand the highly complex functions and the chemistry behind them. While many facts remain undiscovered, this MRW has been contributed to by a large number of the world’s leading researchers in the field.

Book Description
During the last decade a wealth of new data has arisen from the use of new fluorescent labelling techniques and the sequencing of whole microbial genomes. One important conclusion from these data is that bacterial cells are much more structured than previously thought. The wall and the outer membrane contain topological domains, some proteins localize or move in specific patterns inside the cells, and some genes appear clustered in the chromosome and form conserved evolutionary units. Many of these structures are related to the cell cycle and to the process of cell morphogenesis, two processes that are themselves related to each other. From these observations the dcw gene cluster appears as a phylogenetic trait that is mainly conserved in bacilli. Molecules in Time and Space reviews the data on the formation of subcellular patterns or structures in bacteria, presents observations and hypotheses on the establishment and the maintenance of cell shape, and on the organization of genetic information in the chromosome.

Book Description
One of the most profound paradigms that have transformed our understanding about life over the last decades was the acknowledgement that microorganisms play a central role in shaping the past and present environments on Earth and the nature of all life forms. Each organism is the product of its history and all extant life traces back to common ancestors, which were microorganisms. Nowadays, microorganisms represent the vast majority of biodiversity on Earth and have survived nearly 4 billion years of evolutionary change. Microbial evolution occurred and continues to take place in a great variety of environmental conditions. However, we still know little about the processes of evolution as applied to microorganisms and microbial populations. In addition, the molecular mechanisms by which microorganisms communicate/interact with each other and with multicellular organisms remains poorly understood. Such patterns of microbe-host interaction are essential to understand the evolution of microbial symbiosis and pathogenesis.Recent advances in DNA sequencing, high-throughput technologies, and genetic manipulation systems have enabled studies that directly characterize the molecular and genomic bases of evolution, producing data that are making us change our view of the microbial world. The notion that mutations in the coding regions of genomes are, in combination with selective forces, the main contributors to biodiversity needs to be re-examined as evidence accumulates, indicating that many non-coding regions that contain regulatory signals show a high rate of variation even among closely related organisms. Comparative analyses of an increasing number of closely related microbial genomes have yielded exciting insight into the sources of microbial genome variability with respect to gene content, gene order and evolution of genes with unknown functions. Furthermore, laboratory studies (i.e. experimental microbial evolution) are providing fundamental biological insight through direct observation of the evolution process. They not only enable testing evolutionary theory and principles, but also have applications to metabolic engineering and human health. Overall, these studies ranging from viruses to Bacteria to microbial Eukaryotes are illuminating the mechanisms of evolution at a resolution that Darwin, Delbruck and Dobzhansky could barely have imagined. Consequently, it is timely to review and highlight the progress so far as well as discuss what remains unknown and requires future research. This book explores the current state of knowledge on the molecular mechanisms of microbial evolution with a collection of papers written by authors who are leading experts in the field.

Book Description
Achievements and progress in genome mapping and the genomics of microbes supersede by far those for higher plants and animals, in part due to their enormous economic implication but also smaller genome size. In the post-genomic era, whole genome sequences of animal-associated microbes are providing clues to depicting the genetic basis of the complex host-pathogen relationships and the evolution of parasitism; and to improving methods of controlling pathogens. This volume focuses on a globally important group of intracellular prokaryotic pathogens which affect livestock animals. These include Brucella, Mycobacterium, Anaplasma and Ehrlichia, as well as the protozoan pathogens Cryptosporidium and Theileria, for which genome sequence data is available. Insights from comparative genomics of the microbes described provide clues to the adaptation involved in host-microbe interactions, as well as resources potentially useful for application in future research and product development.
