The term “immunobiotics” has been proposed to define microbial strains able to beneficially regulate the mucosal immune system. Research in immunobiotics has significantly evolved as researchers employed cutting-edge technologies to investigate the complex interactions of these beneficial microorganisms with the immune system. During the last decade, our understanding of immunobiotics-host interaction was profoundly transformed by the discovery of microbial molecules and host receptors involved in the modulation of gut associated immune system, as well as the systemic and distant mucosal immune systems. In recent years, there has been a substantial increase in the number of reports describing the beneficial effects of immunobiotics in diseases such as intestinal and respiratory infections, allergy, inflammatory bowel disease, obesity, immunosuppression, and several other immune-mediated conditions. Evidence is also emerging of immunobiotics related molecules with immunomodulatory functions leading to the production of pharmabiotics, which may positively influence human or animal health. Therefore, research in immunobiotics continue to contribute not only to food but also medical and pharmaceutical fields. The compilation of research articles included in this ebook should help reader to have an overview of the recent advances in immunobiotics.

Probiotics in The Prevention and Management of Human Diseases: A Scientific Perspective addresses the use of probiotics and their mechanistic aspects in diverse human diseases. In particular, the mechanistic aspects of how these probiotics are involved in mitigating disease symptoms (novel approaches and immune-mechanisms induced by Probiotics), clinical trials of certain probiotics, and animal model studies will be presented through this book. In addition, the book covers the role of probiotics in prevention and management aspects of crucial human diseases, including multidrug resistant infections, hospital acquired infections, allergic conditions, autoimmune diseases, metabolic disorders, gastrointestinal diseases, neurological disorders, and cancers. Finally, the book addresses the use of probiotics as vaccine adjuvants and as a solution for nutritional health problems and describes the challenges of using probiotics in management of human disease conditions as well as their biosafety concerns. Intended for nutrition researchers, microbiologists, physiologists, and researchers in related disciplines as well as students studying these topics require a resource that addresses the specific role of probiotics in the prevention and management of human disease. - Contains information on the use of probiotics in significant human diseases, including antibiotic resistant microbial infections - Presents novel applications of probiotics, including their use in vaccine adjuvants and concept of pharmabiotics - Includes case studies and human clinical trials for probiotics in diverse disease conditions and explores the role of probiotics in mitigation of the symptoms of disease

Through five editions, and since 1993, Lactic Acid Bacteria: Microbiological and Functional Aspects has provided readers with information on how and why fermentation by lactic acid-producing bacteria improves the shelf life, palatability, and nutritive value of perishable foods and also how these microbes have been used as probiotics for decades. Thoroughly updated (with the current lactobacilli taxonomy) and fully revised, with a rearrangement of chapters into four sections, the Sixth Edition covers new findings on health effects, properties, production and stability of LAB as well as regulatory aspects globally. The new edition also addresses the technological use of LAB in various fermentations of food, feed, and beverage and their safety considerations. It also includes the rising concept of postbiotics and discusses new targets such as cognitive function, metabolic health, and respiratory health. Key Features: In 42 chapters, divided into 4 sections, findings are presented on health effects, properties and stability of LAB as well as production of target-specific LAB. Covers the revised ‘Lactobacillus’ taxonomy Addresses novel topics such as postbiotics Presents new discoveries related to the mechanisms of actions of lactic acid bacteria Covers the benefits of LAB in fermentation of dairy, cereal, meat, vegetable and silage, including non-Western traditional fermented foods from Africa and Asia Discusses the less-known role of LAB as food spoilers Reports on the health benefits of LAB on humans and animals Covers the global regulatory framework related to safety and efficacy

The world’s population is predicted to hit 9 Billion by 2050, and with it food demand is predicted to increase substantially. The World Bank estimates that cereal and meat production needs to increase by 50% and 85% respectively between 2000 and 2030 to meet demand, putting serious pressure on the global agricultural industry. Critical to meeting this demand for food are mechanisms to reduce the incidence of animal disease. With in excess of 1.3 billion cattle globally, the total cost of infectious diseases is difficult to estimate. However in North America alone, the cost is predicted to be $18 billion annually. Non-infectious diseases also account for another major impediment to the production capacity and welfare of animals as well as the economic sustainability of farming. However animal diseases have implications that spread far beyond the farm gate. Infectious agents can also contaminate the food chain, and potentially affect human health. Controlling diseases, through better preventative and treatment methods requires a detailed understanding of the immune response in livestock species. Multiple studies have identified associations between variation in immune genes and disease susceptibility, which potentially opens up new avenues to select animals with superior disease resistance. Detailed understanding of immunity in cattle is leading to the design of more effective vaccines. Furthermore, appreciation of the significant differences between rodent and human immune responses has also led to bovine models being developed for some human diseases. The publication of the bovine genome and the advent of next-generation sequencing technologies have facilitated a massive expansion in our knowledge of the immune response in cattle. As a result there has been an explosion of exciting research findings including in metagenomics and epigenetics. Recently, there has been a welcome move to integrate our emerging understanding of the immune response with detailed studies of other important physiological processes including nutrition and reproduction. The interactions between the reproductive system, nutrition and the immune system are of particular interest, since each places significant demands on the animal at various stages through the production cycle. The interplay between these morphologically diffuse systems involves widely distributed chemical signals in response to environmental input, and each system must interact for the normal functioning of the other. A comprehensive “systems” approach is improving our understanding of normal physiological interactions between these systems and furthermore, how dysregulation can lead to disease. The successful translation of bovine immunological research into improved treatments for animal disease requires tight interaction between diverse scientific and clinical disciplines including immunology, microbiology, endocrinology, physiology, nutrition, reproduction and clinical veterinary medicine. With so much recent progress in the field, we believe that it is valuable and well-timed to review the broad variety of the relevant studies that attempt to increase our understanding through comprehensive collaboration between these disciplines. We are looking forward to a wide and vivid discussion of developments in bovine immunology and related issues, and we expect that our readers profoundly benefit from new exciting insights and fruitful collaborations.
