This book focuses on probiotics with antiviral activities. The "antiviral probiotic" is a new concept in medical sciences. Recently, studies have shown that antiviral probiotics can fight or prevent viral infections in many ways. The immunomodulation of mucosal immunity, production of antiviral compounds, virus trapping and the use thereof as vaccination vectors are the principal modes of action of antiviral probiotics. The author dedicates an entire chapter of the book to discussing the methods and techniques used to assess the antiviral activity of probiotic strains and their metabolites.

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.

Probiotic microorganisms are recognised as being beneficial for human health. Prebiotics are substrates that are used preferentially by the probiotic bacteria for their growth. A great deal of interest has been generated in recent years in identifying probiotic bacteria and prebiotics, their characterization, mechanisms of action and their role in the prevention and management of human health disorders. Together they are referred to as synbiotic. This book is in response to the need for more current and global scope of probiotics and prebiotics. It contains chapters written by internationally recognized authors. The book has been planned to meet the needs of the researchers, health professionals, government regulatory agencies and industries. This book will serve as a standard reference book in this important and fast-growing area of probiotics and prebiotics in human nutrition and health.

The novel coronavirus 2019 (COVID-19) has caused a serious global pandemic in just one year. Nearly every country and territory in the world has been affected by the virus. The virulence and infection rate of the virus are profound, and has required extreme social distancing measures across the globe in order to prevent overwhelming the healthcare services and hospitals. COVID-19 appears to have the greatest effects on elderly individuals and those who have co-morbid diseases, such as diabetes and obesity. As the cases and death rate remain high, there are justified fears of this virus remaining for several months or years to come. To address this, a rapid and unprecedented worldwide mobilization effort has begun to identify effective treatments and develop vaccines. As these begin to be deployed and administered across the globe, many now feel the virus will be brought under control and lives will eventually return to normal. This new volume will increase readers’ understanding of the ongoing COVID-19 pandemic through a series of chapters that address these concerns. Leading experts will discuss new treatment approaches, vaccine development, mental health aspects of the pandemic, and convey the results of survey studies. The book will be an excellent resource for researchers studying virology, metabolic diseases, respiratory disorders, and clinical scientists, physicians, drug companies, and healthcare services and workers.

Composed of nearly a thousand different types of microorganisms - some beneficial, others not - the human gut microbiota plays an important role in health and disease. This is due to the presence of probiotic or beneficial microbes, or due to the feeding of prebiotics that stimulate the endogenous beneficial microbes (these promote health by stimulating the immune system, improving the digestion and absorption of nutrients, and inhibiting the growth of pathogens). The notable health benefits of probiotic organisms have prompted much commercial interest, which in turn has led to a plethora of research initiatives in this area. These range from studies to elucidate the efficacy of the various health benefits to analyses of the diet-microbe interaction as a means of modulating the gut microbiota composition. Research in this area is at a very exciting stage. With state-of-the-art commentaries on all aspects of probiotics and prebiotics research, this book provides an authoritative and timely overview of the field. Written by leading international researchers, each chapter affords critical insight to a particular topic, reviews current research, discusses future direction, and stimulates discussion. Topics range from the different microorganisms used as probiotics (lactobacilli, bifidobacteria, yeast, etc.), and the techniques and approaches used (metagenomics, etc.), to the reviews of the clinical and medical aspects. The provision of extensive reference sections positively encourages readers to pursue each subject in greater detail. *** Librarians: ebook available on ProQuest and EBSCO [Subject: Microbiology, Life Science]

The rapid rise in Covid-19 infection to a pandemic stage in the face of lack of few choices for treatment, prevention has taken a special purpose in this battle. The 1918 Spanish Flu with no vaccine to protect against the infection and no antibiotics to treat secondary bacterial infections associated with influenza infections, control efforts worldwide were limited to non-pharmaceutical interventions including, isolation, quarantine, good personal hygiene, use of disinfectants, and limitations of public gatherings, which were applied unevenly. These same measures hold good for Covid-19 pandemic today. Nutraceuticals and Functional foods for many reasons, largely its perceived safety, have gained popularity in disease prevention. Also, in the last 2-3 decades there have been well designed and controlled basic and clinical investigations that have steadily added credence to nutraceuticals for disease prevention. This book is a compilation of reviews of data on different nutraceuticals that may be of relevance to Covid-19 pandemic. These include, probiotics, melatonin, plant bioactive, lipoic acid, curcumin, selenium, zinc, magnesium and boron to name some.

The 21st century has witnessed a complete revolution in the understanding and description of bacteria in eco- systems and microbial assemblages, and how they are regulated by complex interactions among microbes, hosts, and environments. The human organism is no longer considered a monolithic assembly of tissues, but is instead a true ecosystem composed of human cells, bacteria, fungi, algae, and viruses. As such, humans are not unlike other complex ecosystems containing microbial assemblages observed in the marine and earth environments. They all share a basic functional principle: Chemical communication is the universal language that allows such groups to properly function together. These chemical networks regulate interactions like metabolic exchange, antibiosis and symbiosis, and communication. The National Academies of Sciences, Engineering, and Medicine's Chemical Sciences Roundtable organized a series of four seminars in the autumn of 2016 to explore the current advances, opportunities, and challenges toward unveiling this "chemical dark matter" and its role in the regulation and function of different ecosystems. The first three focused on specific ecosystemsâ€"earth, marine, and humanâ€"and the last on all microbiome systems. This publication summarizes the presentations and discussions from the seminars.
