Book excerpt: The extremely potent substance botulinum neurotoxin (BoNT) has attracted much interest in diverse fields. Originally identified as cause for the rare but deadly disease botulism, military and terrorist intended to misuse this sophisticated molecule as biological weapon. This caused its classification as select agent category A by the Centers for Diseases Control and Prevention and the listing in the Biological and Toxin Weapons Convention. Later, the civilian use of BoNT as long acting peripheral muscle relaxant has turned this molecule into an indispensable pharmaceutical world wide with annual revenues >$1.5 billion. Also basic scientists value the botulinum neurotoxin as molecular tool for dissecting mechanisms of exocytosis. This book will cover the most recent molecular details of botulinum neurotoxin, its mechanism of action as well as its detection and application.

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.

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.

This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Classical clostridial neurotoxins including tetanus neurotoxin and seven antigenically distinct serotypes of botulinum neurotoxin are potent proteinaceous toxins composed of three functional domains. Responsible for the paralytic diseases tetanus and botulism, the clostridial neurotoxin family is produced by multiple species of Clostridium and localizes to plasmids, bacteriophage, and the bacterial chromosome suggestive of a deep history of horizontal gene transfer. In Group I Clostridium botulinum, the species responsible for most human foodborne botulism cases, three serotypes of botulinum neurotoxins occur both within a family of large conjugative plasmids and at discrete sites within the chromosome. To further understand the transfer and localization of these toxins in Group I C. botulinum, a bioinformatic survey of CRISPR-Cas systems was conducted to test whether these endogenous genomic defense complexes play a potential role regulating toxin transfer at the species level. No evidence was found for direct targeting of botulinum neurotoxin associated genes by CRISPR-Cas systems, but CRISPR-Cas systems were predicted to frequently target botulinum neurotoxin producing, conjugative plasmids. Further, these plasmids themselves were found to possess a unique nuclease deficient variant of the type I-B CRISPR-Cas system, which could play roles in plasmid incompatibility, maintenance, and survival. Coupled with the high frequency of chromosomally localized type I and III CRISPR-Cas systems, these results indicate that CRISPR-Cas systems are tolerant of botulinum toxins as an accessory gene product but may nonetheless play a significant role in the regulation of their trafficking throughout Group I C. botulinum. Since 2015, a fast-growing outgroup of botulinum-like toxins have been identified in diverse bacterial species within and beyond genus Clostridium. These homologous toxins possess comparable domain structures to clostridial neurotoxins and are frequently conserved at key functional motifs capable of enzymatically cleaving known botulinum substrates. These attributes make them excellent tools for exploring the evolution of clostridial neurotoxins and may additionally confer unique and pharmacologically desirable activities. However, their capacity to cause disease akin to tetanus or botulism at similar potency to the classical toxin family remains largely unknown. Recombinant expression of a botulinum-like toxin from Enterococcus demonstrated a capacity to cause botulism in mice, though this required a significantly larger quantity of toxin relative to the classical neurotoxin serotypes. Chimeric constructs composed of the enzymatic and translocative domains of the botulinum-like toxin and binding domain of botulinum serotype A was intermediately toxic between the two. These findings coupled with mixed toxicity results from additional botulinum-like toxins indicates botulinum-like toxins vary significantly in mammalian potency and function, requiring investigation on a case-by-case basis.

Available in PDF, EPUB and Kindle. Book excerpt: Botulinum Neurotoxin and Tetanus Toxin covers the mechanism of action, pathogenesis, and treatment of clostridial neurotoxins. The book is organized into four parts encompassing 18 chapters that discuss the origin, structure, pharmacology, toxicology, immunology, assays, and clinical issues of botulinum and tetanus neurotoxins. The introductory part of the book discusses the discovery and production of neurotoxins in various strains of Clostridium bacteria. This text also describes how specific bacteriophages and plasmids mediate the pathogenicity of some types of Clostridium botulinum and Clostridium tetani. The subsequent part provides an overview of issues related to toxin binding, including toxins that may serve as models for botulinum and tetanus neurotoxins. Discussions on the peripheral and central aspects of poisoning transport in the central nervous system and on the antagonistic drugs for clostridial neurotoxins are provided. The third part of the book addresses the antibodies against botulinum neurotoxin. Bioassay in mice and highly sensitive immunoassays, such as reversed passive hemagglutination, reversed passive latex agglutination, radioimmunoassay, and enzyme-linked immunosorbent assay, are presented. The concluding part covers the animal models for these toxins and discusses the diagnosis and treatment of botulism and tetanus in human. The clinical use of Clostridium botulinum toxin type A in ocular and neuromuscular disease is also examined. This book will be of value to protein chemists, microbiologists, virologists, pharmacologists, immunologists, and clinicians.

Available in PDF, EPUB and Kindle. Book excerpt: Three days in Madison have thoroughly modified my view on clostridial neurotoxins. While still realizing the numerous activating, modifying and protective inputs, I cannot judge the meaningfulness of the meeting impartially. Neither may the reader expect a complete summary of all presentations. Collected in this volume, they speak for themselves without requiring an arbiter. Instead I shall write down my very personal opinions as a researcher who has studied clostridial neurotoxins for nearly 25 years. Comparable conferences have been rare during this time. A comprehensive symposium 4 on C. botulinum neurotoxins has been organized at Ft. Detrick. International conferences on tetanus have been held regularly under the auspices of the Wodd Health Organization. One or maximally two days of these meetings have been devoted to tetanus toxin and its actions whereas the sponsor and the majority of the participants have been interested mainly in epidemiology, prevention and treatment of tetanus as a disease (see refs. 5,6). Some aspects of clostridial neurotoxins have been addressed in the context of bacterial toxins, in particular in the biennial European workshops. 1-3,7,8 The Madison meeting differed from the previous ones in three aspects. First, it covered both tetanus and botulinum neurotoxins. The fusion was justified because of their huge similarities in primary structure, in their mode of action and in their cellular targets. Second, the meeting was not limited to toxins but drew some lines on which modern neurobiology might proceed.

Download or read book Human Emerging and Re emerging Infections written by Sunit Kumar Singh and published by John Wiley & Sons. This book was released on 2015-11-09 with total page 2365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emerging and re-emerging pathogens pose several challenges to diagnosis, treatment, and public health surveillance, primarily because pathogen identification is a difficult and time-consuming process due to the “novel” nature of the agent. Proper identification requires a wide array of techniques, but the significance of these diagnostics is anticipated to increase with advances in newer molecular and nanobiotechnological interventions and health information technology. Human Emerging and Re-emerging Infections covers the epidemiology, pathogenesis, diagnostics, clinical features, and public health risks posed by new viral and microbial infections. The book includes detailed coverage on the molecular mechanisms of pathogenesis, development of various diagnostic tools, diagnostic assays and their limitations, key research priorities, and new technologies in infection diagnostics. Volume 1 addresses viral and parasitic infections, while volume 2 delves into bacterial and mycotic infections. Human Emerging and Re-emerging Infections is an invaluable resource for researchers in parasitologists, microbiology, Immunology, neurology and virology, as well as clinicians and students interested in understanding the current knowledge and future directions of infectious diseases.
