Book Description
As our understanding of mobile genetic elements continues to grow we are gaining a deeper appreciation of their importance in shaping the bacterial genome and in the properties they confer to their bacterial hosts. These include, but are by no means limited to, resistance to antibiotics, and heavy metals, toxin production and increased virulence, production of antibiotics and the ability to utilize a diverse range of metabolic substrates. We are also gaining an understanding of diversity of these elements and their interactions with each other; a property which continually complicates any attempt to classify them. We are learning more about the molecular mechanisms by which they translocate to new genomic sites both within genomes and between different bacteria. This book provides a timely, state of the art update on the properties of an important selection of different bacterial integrative mobile genetic elements and the myriad of different ways in which they move and influence the biology of the host bacterium. The chapters are all written by authors who have undertaken pioneering work in their respective fields, making this book vital reading for all who are interested in the biology of bacteria and the mobile elements they carry.

Mobile Genetic Elements
Author: James Shapiro
Publisher: Elsevier
ISBN: 0323143199
Category : Science
Languages : en
Pages : 707
Book Description
Mobile Genetic Elements introduces the nonspecialist to the biology and genetics of mobile elements. It attempts to make the biochemistry of DNA rearrangements more accessible to embryologists and evolutionists, and to illuminate the related developmental cycles to the biochemist. The book also shows how natural the activity of mobile elements can be in diverse biological situations. The chapters describe several well-studied cases in which genetic determinants—often identified as specific nucleic acid sequences—repeatedly change their positions within or between cellular genomes. Because their genomic positions are not fixed, these determinants may conveniently be classed together under the rubric of mobile genetic elements. The book begins with a discussion of maize controlling elements. This is followed by separate chapters on the bacteriophages ? and Mu; nonviral mobile elements in bacteria; transposable Ty elements in brewer's yeast; Drosophila transposable element; and hybrid dysgenesis. Subsequent chapters cover vertebrate retroviruses; Agrobacterium oncogenesis in plants; flagellar phase variation in Salmonella; yeast mating type; and surface antigenic variation in trypanosomes.

Languages : en
Pages : 214
Book Description
The 35th N:osbach Colloquium "The Impact of Gene Transfer Techniques in Eukaryotic CeU Biology" brought together a number of speakers interested in various aspects of cellular and developmental biology and over 600 other scientists, who listened to the lectures and participated in the lively discussions. The questions and experiments described were very varied, but all of them illustrated the importance of recombinant DNA technology. The powerful techniques of identifying and isolating DNA sequences, followed by their introduction into living cells and even into the germ cells of multicellular organisms, have pervaded nearly every branch of molecular biology. The presentations and discussions that followed showed that recombinant DNA has tremendously increased our potential for fundamental research. Now, and for some time to corne, these contri butions and the resulting increase in our understanding of life will be the main result of gene manipulation. There will, however, also be applications that will lead to new industrial processes. One section was devoted to novel ways of vaccine production and another to herbicide resistance. These applications are a matter of intense debate in the public domain today. Although they reach beyond the scope of the research labora.tory at a university or research institution, scientists have the knowledge necessary to judge these developments and are sometimes directly involved. There fore the development of industrial qene technology requires the attention of the whole scientific community. We hope that this Symposium has also served this purpose.

Evolution and Impact of Transposable Elements
Author: Pierre Capy
Publisher: Springer Science & Business Media
ISBN: 9401148988
Category : Science
Languages : en
Pages : 305
Book Description
During the last 50 years, the perception oftransposable elements (TEs) has changed considerably from selfish DNA to sequences that may contribute significantly to genome function and evolution. The recent increased interest in TEs is based on the realization that they are a major genetic component (at least 10--20%) of all organisms and a major contributor to the mutation process. It is currently estimated that 70--80% of spontaneous mutations are the result of TE-mediated insertions, deletions, or chromosomal rearrangements. Thus, it seems at least plausible that TEs may playa significant role in the adaptation and evolution of natural populations and species. The ubiquity of TEs suggests that they are an old component of genomes which have been vertically transmitted through generations over evolutionary time. However, detailed analyses carried out over the last 20 years have revealed several unusual features of TE evolution: (i) TEs can be horizontally transferred between species; (ii) TE evolutionary rates can be dramatically increased by specific inactivation processes, such as the RIP (Repeat Induced Point mutation) mechanism in fungi; (iii) TEs can influence the regulation of other TEs by insertion or deletion; (iv) different classes of TEs in even distantly related species can be remarkably similar in both structure and function.

Antibiotic Resistance

ISBN: 0470515368
Category : Medical
Languages : en
Pages : 260
Book Description
Antibiotic Resistance: Origins, Evolution, Selection and Spread Chairman: Stuart B. Levy, 1997 Over the last 50 years, the rapid increase in the use of antibiotics, not only in people, but also in animal husbandry and agriculture, has delivered a selection unprecedented in the history of evolution. Consequently, society is facing one of its gravest public health problems-the emergence of infectious bacteria with resistance to many, and in some cases all, available antibiotics. This book brings together a multidisciplinary group of experts to discuss this problem. It begins by examining the origins of resistance and goes on to look at how the use of antibiotics in human medicine and farming/agriculture has selected for resistant bacteria. Separate chapters describe the evolution of resistance determinants and how these are spread both within and between bacterial species. Finally, the book contains discussions on strategies for countering the threat of antibiotic resistance. A major re-thinking of our approach to the treatment of infectious diseases is proposed-that antibiotic resistance should be seen as a problem created by the disruption of normal microbial ecology. To restore efficacy to earlier antibiotics, and to maintain the success of new antibiotics that are introduced, we need to use these drugs in a way that ensures an ecological balance that favours the predominance of susceptible bacteria.

Systems Biology and Antimicrobial Drug Resistance
Author: Vijay Soni
Publisher: Frontiers Media SA
ISBN: 283255427X
Category : Science
Languages : en
Pages : 244
Book Description
Antimicrobial resistance (AMR) poses a significant threat to global public health. With the emergence of new resistant strains and limited antibiotic treatment options, it has become increasingly difficult to treat infections effectively. This is particularly concerning for bacterial infections like Mycobacterium tuberculosis, Acinetobacter spp., Staphylococcus aureus, and Pseudomonas aeruginosa, where only a limited number of antibiotics are available for treatment. According to the US National Strategy for Combating Antibiotic-Resistant Bacteria, approximately 2 million Americans are infected with antibiotic-resistant bacteria each year, and at least 23,000 die as a result. The situation is even worse in developing countries. Systems biology, which aims to understand the complex interactions between the different components of a biological system, has emerged as a powerful tool for studying AMR. By integrating data from multiple sources, including genomics, transcriptomics, proteomics, and metabolomics, systems biology can provide a comprehensive view of the mechanisms underlying AMR. This approach can lead to the identification of novel targets for drug development and the development of personalized treatment strategies that consider the specific characteristics of individual patients and the pathogens that infect them. This Research Topic aims to explore the potential of systems biology in combating antibiotic resistance, and highlight the need for further research to fully realize its clinical potential in infectious diseases.
