Bacterial Conjugation by D.B. Clewell Pdf

Bacterial plasmids originating in a wide range of genera are being studied from a variety of perspectives in hundreds of laboratories around the globe. These elements are well known for carrying "special" genes that confer important survival properties, frequently neces sary under atypical conditions. Classic examples of plasmid-borne genes are those provid ing bacterial resistance to toxic substances such as antibiotics, metal ions, and bacte riophage. Often included are those determining bacteriocins, which may give the bacterium an advantage in a highly competitive environment. Genes offering metabolic alternatives to the cell under nutritionally stressed conditions are also commonly found on plasmids, as are determinants important to colonization and pathogenesis. It is likely that in many, if not most, cases plasmids and their passenger determinants represent DNA acquired recently by their bacterial hosts, and it is the characteristic mobility of these elements that enables their efficient establishment in new bacterial cells by the process known as conjugation. Whereas many plasmids are fully capable of promoting their own conjugal transfer, others move only with help from coresident elements. The ability of a plasmid to establish itself in a variety of different species is com mon, and recent studies have shown that transfer can in some cases occur from bacterial cells to eukaryotes such as yeast.

Bacterial Plasmids by Geoffrey Guy Meynell Pdf

This is a sound, scholarly, yet very readable book that organizes the pertinent material on a relatively popular topic in bacterial genetics. In a complicated area where articles are scattered throughout the literature, it should prove an excellent reference source for researchers in microbial genetics and general microbiology, as well as in certain aspects of clinical medicine and in nutrition. Drug-resistance factors are accessory chromosomes, independent of the bacterial chromosome proper, which are of increasing practical concern as they cause a large portion of the antibiotic resistance that is prevalent in medicine and in veterinary practice. Yet these factors are only part of a much larger class of accessory chromosomes known as &"plasmids&" which have played a prominent role in the development of bacterial genetics of molecular biology as a whole. Two other well-known classes are the sex factors, which enable bacteria to transfer their genes to recipients by conjugation, and the bacterial phages&-viruses that grow in bacteria. Despite the great differences in their overt properties, all plasmids exhibit strong fundamental similarities, and it is these general properties rather than their individual peculiarities which are emphasized here. The book first notes how plasmids were discovered. It then discusses the physical structure of their chromosomes, their manner of replication, how they act to bring about conjugation, and other processes they determine. Although the treatment is primarily biological, the book supplies references to laboratory techniques and to the implications of the subject for human and for animal medicine.

The Dynamic Bacterial Genome by Peter Mullany Pdf

"This book provides an in-depth analysis of the mechanisms and biological consequences of genome rearrangements in bacteria. Each chapter examines the mechanisms involved in genome rearrangements and the direct biological consequences of these events. Because genome rearrangements are so important in evolution, at least one of the chapters views the phenomenon from an evolutionary angle. This book provides the reader with a holistic view of genome rearrangements (i.e., studies on both the biological consequences of genome rearrangement and the mechanisms underlying these processes are presented)." "The book is written by leading research workers in the field and is aimed at final-year undergraduates, postgraduate and postdoctoral workers, and established biologists."--BOOK JACKET.

Plasmid Biology by Gregory Phillips,Barbara E. Funnell Pdf

This book opens with an essay on the historical perspective of the study of plasmids, reviewing important events and discoveries that have propelled the field forward. The remaining chapters are divided into six sections, detailing basic biological processes such as replication and inheritance functions, specific plasmid systems, plasmid evolution, and use of plasmids as genetic tools. Chapters include use of genomic approaches for the study of plasmid biology, and a review of plasmids from bacteria, archaea, and eukaryotes is presented. In-depth treatment is given to diversity of plasmid systems in the natural environment, and the development of plasmid use in the laboratory is also covered.

Molecular Microbiology by Stephen J.W. Busby,Christopher M. Thomas,Nigel L. Brown Pdf

Molecular microbiology is a rapidly expanding area of contemporary science: the application of molecular biology has opened up the microbial world in many remarkable ways. The attraction of microbes is that they are self-contained and that they offer complete solutions to understanding the phenomenon of life. This book provides a concise introduction to current research in the field. Four major areas are introduced and explained: - Bacterial Biochemistry - Bacterial Genomes - Gene Expression - Microbial Cell Biology

Cell-Cell Channels by František Baluška,Dieter Volkmann,Peter W. Barlow Pdf

This book covers cell-cell channels at all levels of biological organization. The purpose of this book is to document that cells are not physically separated and fully autonomous units of biological life as stated by the currently valid Cell Theory. If not the cell then some lower level unit must fulfill this role. The book deals also with the identity of this elusive unit of biological life.

Bacterial Genetics in Natural Environments by J.C. Fry,M.J. Day Pdf

This book has arisen from the Second European Meeting on Bacterial Genetics and Ecology (Bageco-2) held at the University of Wales, College of Cardiff which we organised on 11-12 April 1989. The meeting was attended by some 60 participants from eight European countries and was made possible by partial financial support from the Commission of the European Communities (CEC) and Imperial Chem ical Industries (UK) Ltd. The meeting was organised to discuss modern developments in the genetics of bacteria in aquatic and terrestrial habitats. It followed on from, and complemented, the first meeting of this series organised by Jean-Pierre Gratia in Brussels during April 1987 which concentrated more on medical and epidemiological issues. ! The next meeting will be organised by Michel J. Gauthier in 1991 at Nice, France. If you have been fired with enthusiasm for ecological bacterial genetics after having read this book, and want to attend the next meeting but did not hear about the one in Cardiff, you should write to Dr Gauthier to be put on the address list. A lot is now known about bacterial genetics at the physiological, biochemical and molecular level, and bacterial ecology has developed rapidly over the last 20 years. However, until very recently, few researchers have crossed the divide and linked these two specialisms.

The Biology of Plasmids by David Summers Pdf

Plasmids are closed, circular pieces of DNA that are able to self-replicate and are carried by many bacteria. They provide unique functions for bacteria by allowing them to sexually replicate and to pass on genetic material between each other. Plasmids are also responsible for the genetic factors that give resistance to antibiotics, and provide the enzymes needed to break down poorly metabolised food resources. The author has provided an updated treatment of the structure, function and application of plasmids suitable for undergraduates and medical students. Employing an original teaching perspective--examining plasmids as living organisms with either a symbiotic or parasitic mode of survival--this text provides an important framework for understanding the structure and function of plasmids in an evolutionary context. The most up to date text on plasmids An innovative teaching perspective makes for easy student understanding Contains crucial chapters on the importance of plasmids for clinical and biological research
