Download or read book Toxin Antitoxin Systems in Pathogenic Bacteria written by Juan Carlos Alonso and published by Mdpi AG. This book was released on 2021-06-17 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bacterial toxin-antitoxin (TA) systems, which are ubiquitously present in bacterial genomes, are not essential for normal cell proliferation. The TA systems regulate fundamental cellular processes, facilitate survival under stress conditions, have essential roles in virulence and represent potential therapeutic targets. These genetic TA loci are also shown to be involved in the maintenance of successful multidrug-resistant mobile genetic elements. The TA systems are classified as types I to VI, according to the nature of the antitoxin and to the mode of toxin inhibition. Type II TA systems encode a labile antitoxin and its stable toxin; degradation of the antitoxin renders a free toxin, which is bacteriostatic by nature. A free toxin generates a reversible state with low metabolic activity (quiescence) by affecting important functions of bacterial cells such as transcription, translation, DNA replication, replication and cell-wall synthesis, biofilm formation, phage predation, the regulation of nucleotide pool, etc., whereas antitoxins are toxin inhibitors. Under stress conditions, the TA systems might form networks. To understand the basis of the unique response of TA systems to stress, the prime causes of the emergence of drug-resistant strains, and their contribution to therapy failure and the development of chronic and recurrent infections, must be known in order to grasp how TA systems contribute to the mechanisms of phenotypic heterogeneity and pathogenesis that will enable the rational development of new treatments for infections caused by pathogens.

Download or read book Prokaryotic Toxin Antitoxins written by Kenn Gerdes and published by Springer Science & Business Media. This book was released on 2012-10-19 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Prokaryotic Toxins – Antitoxins gives the first overview of an exciting and rapidly expanding research field. Toxin – antitoxin (TA) genes were discovered on plasmids 30 years ago. Since then it has become evident that TA genes are highly abundant in bacterial and archaeal chromosomes. TA genes code for an antitoxin that combine with and neutralize a cognate toxin. When activated, the toxins inhibit protein synthesis and cell growth and thereby induce dormancy and multidrug tolerance (persistence). Remarkably, in some species, the TA gene families have undergone dramatic expansions. For example, the highly persistent major human pathogen Mycobacterium tuberculosis has »100 TA loci. The large expansion of TA genes by some organisms is a biological mystery. However, recent observations indicate that TA genes contribute cumulatively to the persistence of bacteria. This medically important phenomenon may thus for the first time become experimentally tractable at the molecular level.

Download or read book Microbial Toxins written by P. Gopalakrishnakone and published by Springer. This book was released on 2018-03-14 with total page 502 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the field of Toxinology has expanded substantially. On the one hand it studies venomous animals, plants and micro organisms in detail to understand their mode of action on targets. While on the other, it explores the biochemical composition, genomics and proteomics of toxins and venoms to understand their three interaction with life forms (especially humans), development of antidotes and exploring their pharmacological potential. Therefore, Toxinology has deep linkages with biochemistry, molecular biology, anatomy and pharmacology. In addition, there is a fast developing applied subfield, clinical toxinology, which deals with understanding and managing medical effects of toxins on human body. Given the huge impact of toxin-based deaths globally, and the potential of venom in generation of drugs for so-far incurable diseases (for example, Diabetes, Chronic Pain), the continued research and growth of the field is imminent. This has led to the growth of research in the area and the consequent scholarly output by way of publications in journals and books. Despite this ever growing body of literature within biomedical sciences, there is still no all-inclusive reference work available that collects all of the important biochemical, biomedical and clinical insights relating to Toxinology. The Handbook of Toxinology aims to address this gap and cover the field of Toxinology comprehensively.

Download or read book Origin of Group Identity written by Luis P. Villarreal and published by Springer Science & Business Media. This book was released on 2008-12-10 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: A sense of belonging is basic to the human experience. But in this, humans are not unique. Essentially all life, from bacteria to humans, have ways by which it determines which members belong and which do not. This is a basic cooperative nature of life I call group membership which is examined in this book. However, cooperation of living things is not easily accounted for by current theory of evolutionary biology and yet even viruses display group membership. That viruses have this feature would likely seem coincidental or irrelevant to most scientist as having any possible relationship to human group identity. Surely such simple molecular-based relationships between viruses are unrelated to the complex cognitive and emotional nature of human group membership. Yet viruses clearly affect bacterial group membership, which are the most diverse and abundant cellular life form on Earth and from which all life has evolved. Viruses are the most ancient, numerous and adaptable biological entities we know. And we have long recognized them for the harm and disease they can cause, and they have been responsible for the greatest numbers of human deaths. However, with the sequencing of entire genomes and more recently with the shotgun sequencings of habitats, we have come to realize viruses are the black hole of biology; a giant force that has until recently been largely unseen and historically ignored by evolutionary biology. Viruses not only can cause acute disease, but also persist as stable unseen agents in their host.

Download or read book Biological Toxins and Bioterrorism written by P. Gopalakrishnakone and published by Springer. This book was released on 2015-01-22 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological toxins are an important part of our world, a reality with which we need to cope, so in parallel with understanding their mechanisms of action and thereby improving our fundamental knowledge, there are successful efforts to utilize them as therapeutics against some debilitating human and animal diseases. In view of the complexity of different types of biotoxins and the broad range of toxin structure, physiology, utility, and countermeasures including regulatory issues, it was thus aimed to compile a book on biotoxins and bioweapons. This reference work in the Toxinology handbook series gathers together knowledge from around the globe about naturally inspired and manufactured biological weapons. The authors describe how they work; how authorities may detect their presence, prevent their use, and diagnose their impacts; and the means by which medical and paramedical professionals may treat victims. Also described are how they have been used to further our knowledge and what insights they have given us into evolutionary and physiological processes. Finally, it is also discussed how these toxins can be used as therapeutics and what the implications of such therapeutics are to their use as biothreat agents. This volume provides a reference accessible to scientists, educators, and medical experts alike with an interest in biotoxins, focusing on the major toxins used as bioweapons. Regulatory agencies will also benefit from the information provided in this book. Some in the intended audience may need to understand how they elicit their effects and how we can defend ourselves against them. Others may be interested in the sometimes colorful histories that surround this subset of biotoxins that can be and, in some cases, have been used as weapons.

Download or read book Chemical and Biological Terrorism written by Institute of Medicine and published by National Academies Press. This book was released on 1999-03-12 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: The threat of domestic terrorism today looms larger than ever. Bombings at the World Trade Center and Oklahoma City's Federal Building, as well as nerve gas attacks in Japan, have made it tragically obvious that American civilians must be ready for terrorist attacks. What do we need to know to help emergency and medical personnel prepare for these attacks? Chemical and Biological Terrorism identifies the R&D efforts needed to implement recommendations in key areas: pre-incident intelligence, detection and identification of chemical and biological agents, protective clothing and equipment, early recognition that a population has been covertly exposed to a pathogen, mass casualty decontamination and triage, use of vaccines and pharmaceuticals, and the psychological effects of terror. Specific objectives for computer software development are also identified. The book addresses the differences between a biological and chemical attack, the distinct challenges to the military and civilian medical communities, and other broader issues. This book will be of critical interest to anyone involved in civilian preparedness for terrorist attack: planners, administrators, responders, medical professionals, public health and emergency personnel, and technology designers and engineers.

Download or read book Clostridial Neurotoxins written by Cesare Montecucco and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tetanus has been known from the very beginning of medical literature since it was first described by Hyppocrates of Cos in the fifth century B.C. For 24 centuries it was considered a neuro logical disease until the breakthrough of CARLE and RATIONE (1884) who demonstrated its infectious etiology. Following the establishment of purified cultures of Clostridium tetani(KITASATO 1889), FABER (1890), and TIZZONI and CATIANI (1890) demon strated that the disease is actually an intoxication caused by a proteic neurotoxin. This toxin was shown by BRUSHCHETIINI (1892) to move retroaxonally and to act at the spinal cord level. Soon thereafter VAN ERMENGEN (1897) demonstrated that botu lism is also due to intoxication with a protein toxin produced by bacteria of the genus Clostridium. These bacteria and their spores and ubiquitous, and the majority of them do not produce neurotoxins. The selective advantage of producing such potent toxin is still a matter of speculation (see Popoff, this volume). The next major advance was the discovery that tetanus neurotoxin 1 can be converted by formaldehyde treatment to a nonpathogenic but still fully immunogenic form, and that this can be used successfully as a vaccine to prevent tetanus (RAMON and DESCOMBEY 1925). Similar vaccines (toxoids) can be prepared with botulism neurotoxins (see MiDDLEBROOK and BROWN, this volume). The prevention oftetanus by vaccination (see Galatzka and Gasse, this volume) is one of the great successes of basic research coupled with an efficient public medicine service.
