Book Description
To start with, we feel that we should explain why the book has been entitled Cholera Toxins. In fact, the enterotoxin secreted by Vibrio cholerae, which is p- marily responsible for causation of the disease, is conventionally known as or referred to as cholera toxin, or CT. By using the word “toxins” (in its plural form), we wanted to cover all of the different types of toxins—and not just CT—produced by V. cholerae. We could have used the title Toxins of Vibrio cholerae, but we believe that Cholera Toxins is simpler and equally as expressive. However, due to its relative importance, the story of CT covers most of this book. Also, compared to all other toxins of V. cholerae, CT has been investigated more extensively. This book was jointly written by us. It is not a multiauthor book in which each expert writes one chapter. In that respect our task is harder. On the other hand, it has given us the unique opportunity to present the entire subject in the way that we conceived it. Besides, our objective is to cater to the needs of not only active research scientists but also students from different disciplines—microbiology, molecular physiology and pharmacology, basic medicines, etc. —and as such, we have attempted to present the subject in a way that will be appreciated by general readers. Further, we have provided some information that students and predoctoral researchers may find useful at the end of the book.

Book Description
This book describes the major achievements and discoveries relevant to bacterial protein toxins since the turn of the new century illustrated by the discovery of more than fifty novel toxins (many of them identified through genome screening). The establishment of the three-dimensional crystal structure of more than 20 toxins during the same period offers deeper knowledge of structure-activity relationships and provides a framework to understand how toxins recognize receptors, penetrate membranes and interact with and modify intracellular substrates. Edited by two of the most highly regarded experts in the field from the Institut Pasteur, France 14 brand new chapters dedicated to coverage of historical and general aspects of toxinology Includes the major toxins of both basic and clinical interest are described in depth Details applied aspects of toxins such as therapy, vaccinology, and toolkits in cell biology Evolutionary and functional aspects of bacterial toxins evaluated and summarized Toxin applications in cell biology presented Therapy (cancer therapy, dystonias) discussed Vaccines (native and genetically engineered vaccines) featured Toxins discussed as biological weapons, comprising chapters on anthrax, diphtheria, ricin etc.

Book Description
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.

Book Description
Cyanobacterial toxins are among the hazardous substances most widely found in water. They occur naturally, but concentrations hazardous to human health are usually due to human activity. Therefore, to protect human health, managing lakes, reservoirs and rivers to prevent cyanobacterial blooms is critical. This second edition of Toxic Cyanobacteria in Water presents the current state of knowledge on the occurrence of cyanobacteria and cyanotoxins as well as their impacts on health through water-related exposure pathways, chiefly drinking-water and recreational activity. It provides scientific and technical background information to support hazard identification, assessment and prioritisation of the risks posed by cyanotoxins, and it outlines approaches for their management at each step of the water-use system. It sets out key practical considerations for developing management strategies, implementing efficient measures and designing monitoring programmes. This enables stakeholders to evaluate whether there is a health risk from toxic cyanobacteria and to mitigate it with appropriate measures. This book is intended for those working on toxic cyanobacteria with a specific focus on public health protection. It intends to empower professionals from different disciplines to communicate and cooperate for sustainable management of toxic cyanobacteria, including public health workers, ecologists, academics, and catchment and waterbody managers. Ingrid Chorus headed the department for Drinking-Water and Swimming-Pool Hygiene at the German Environment Agency. Martin Welker is a limnologist and microbiologist, currently with bioMérieux in Lyon, France.

Book Description
The last 20 years has seen a rapid increase in infectious diseases, particularly those that are termed "emerging diseases" such as SARS, "neglected diseases" such as malaria and those that are deemed biothreats such as anthrax. It is well-recognized that the most effective modality for preventing infectious diseases is vaccination. This book provides researchers with a better understanding of what is currently known about these diseases, including whether there is a vaccine available or under development. It also informs readers of the key issues in development of a vaccine for each disease. Provides a comprehensive treatise of the agents that are responsible for emerging and neglected diseases and those that can be used as biothreats Includes the processes such as the vaccine development pathway, vaccine manufacturing and regulatory issues that are critical to the generation of these vaccines to the marketplace Each chapter will include a map of the world showing where that particular disease is naturally found

Book Description
Vibrio cholerae is the bacteria responsible for causing cholera, a diarrheal disease. Cholera affects around 1.3 to 4 million people globally and impacts countries that lack access to sanitary drinking water such as Bangladesh. Given the burden of V. cholerae induced infection, we investigated the multifunctional autoprocessing repeats-in-toxin (MARTX) toxin, a secreted toxin. Cholera is typically considered a non-inflammatory disease, and this may be explained by the actions of the MARTX toxin. In this present study, we sought to determine if the MARTX toxin modulated host inflammation to limit bacterial clearance and confer a fitness advantage. Additionally, we wanted to determine whether the actions of MARTX toxin are dependent on V. cholerae's cholera toxin (CT). We found that genetic abrogation of the MARTX toxin was detrimental to the fitness of the pathogen within the gut of the host. At 6 hours post infection we observed a significant reduction in intestinal colonization by the MARTX toxin mutant, rtxA relative to the wild-type (WT) strain. RT-qPCR data reveal that mice infected with the WT and the mice infected with rtxA have non-significant different expression of intestinal inflammation genes, CXCL1, CXCL2 and Nos-2. However, we report that expression of these inflammation markers was greater in rtxA relative to WT after 6 hours and thus, could explain the observed bacterial enumeration data. These results help elucidate the interaction between bacterial toxins and their impact on host innate immunity, which can be further developed into a more effective cholera vaccine or provide therapeutic targets.
