Available in PDF, EPUB and Kindle. Book excerpt: A cup of seawater contains 100 million cells, which are preyed upon by billions of viruses. Fifty million tons of fungal spores are released into the atmosphere every year. And the human gut is home to somewhere between 500 and 1,000 species of bacteria. The more we learn about microbial biodiversity, the clearer it becomes that the vast majority of life has long gone unseen, and unobserved. The flowering of microbial science is revolutionizing biology and medicine in ways unimagined only a few years ago, and is inspiring a new view of what it means to be alive. In The Amoeba in the Room, Nicholas Money explores the extraordinary breadth of the microbial world and the vast swathes of biological diversity that can be detected only using molecular methods. Although biologists have achieved a remarkable level of understanding about the way multicellular organisms operate, Money shows that most people continue to ignore the fact that most of life isn't classified as either plant or animal. Significant discoveries about the composition of the biosphere are making it clear that the sciences have failed to comprehend the full spectrum of life on earth, which is far more diverse than previously imagined. Money's engaging work considers this diversity in all its forms, exploring environments from the backyard pond to the ocean floor to the "mobile ecosystem" of our own bodies. A revitalized vision of life emerges from Money's lively narrative of the lowly, one in which we are challenged to reconsider our existence in proper relationship to the single-celled protists, bacteria, and viruses that constitute most of life on earth. Proposing a radical reformulation of biology education and research in the life sciences, The Amoeba in the Room is a compelling romp through the least visible and yet most prodigiously magnificent aspects of life on earth.
Download or read book The Social Amoebae written by John Tyler Bonner and published by Princeton University Press. This book was released on 2009-01-18 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Noted biologist and author John Tyler Bonner has experimented with cellular slime molds for more than sixty years, and he has done more than anyone else to raise these peculiar collections of amoebae from a minor biological curiosity to a major model organism--one that is widely studied for clues to the development and evolution of all living things. Now, five decades after he published his first pioneering book on cellular slime molds, Bonner steps back from the proliferating and increasingly specialized knowledge about the organism to provide a broad, nontechnical picture of its whole biology, including its evolution, sociobiology, ecology, behavior, and development. The Social Amoebae draws the big lessons from decades of research, and shows how slime molds fit into and illuminate biology as a whole. Slime molds are very different from other organisms; they feed as individual amoebae before coming together to form a multicellular organism that has a remarkable ability to move and orient itself in its environment. Furthermore, these social amoebae display a sophisticated division of labor; within each organism, some cells form the stalk and others become the spores that will seed the next generation. In The Social Amoebae, Bonner examines all these parts together, giving a balanced, concise, and clear overview of slime mold biology, from molecules to cells to multicells, as he advances some unconventional and unexpected insights.

This book was released on 2013-01-10 with total page 633 pages. Available in PDF, EPUB and Kindle. Book excerpt: Beginning with the germ theory of disease in the 19th century and extending through most of the 20th century, microbes were believed to live their lives as solitary, unicellular, disease-causing organisms . This perception stemmed from the focus of most investigators on organisms that could be grown in the laboratory as cellular monocultures, often dispersed in liquid, and under ambient conditions of temperature, lighting, and humidity. Most such inquiries were designed to identify microbial pathogens by satisfying Koch's postulates.3 This pathogen-centric approach to the study of microorganisms produced a metaphorical "war" against these microbial invaders waged with antibiotic therapies, while simultaneously obscuring the dynamic relationships that exist among and between host organisms and their associated microorganisms-only a tiny fraction of which act as pathogens. Despite their obvious importance, very little is actually known about the processes and factors that influence the assembly, function, and stability of microbial communities. Gaining this knowledge will require a seismic shift away from the study of individual microbes in isolation to inquiries into the nature of diverse and often complex microbial communities, the forces that shape them, and their relationships with other communities and organisms, including their multicellular hosts. On March 6 and 7, 2012, the Institute of Medicine's (IOM's) Forum on Microbial Threats hosted a public workshop to explore the emerging science of the "social biology" of microbial communities. Workshop presentations and discussions embraced a wide spectrum of topics, experimental systems, and theoretical perspectives representative of the current, multifaceted exploration of the microbial frontier. Participants discussed ecological, evolutionary, and genetic factors contributing to the assembly, function, and stability of microbial communities; how microbial communities adapt and respond to environmental stimuli; theoretical and experimental approaches to advance this nascent field; and potential applications of knowledge gained from the study of microbial communities for the improvement of human, animal, plant, and ecosystem health and toward a deeper understanding of microbial diversity and evolution. The Social Biology of Microbial Communities: Workshop Summary further explains the happenings of the workshop.
Download or read book Welcome to the Microbiome written by Rob DeSalle and published by Yale University Press. This book was released on 2015-11-10 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: Suddenly, research findings require a paradigm shift in our view of the microbial world. The Human Microbiome Project at the National Institutes of Health is well under way, and unprecedented scientific technology now allows the censusing of trillions of microbes inside and on our bodies as well as in the places where we live, work, and play. This intriguing, up-to-the-minute book for scientists and nonscientists alike explains what researchers are discovering about the microbe world and what the implications are for modern science and medicine. Rob DeSalle and Susan Perkins illuminate the long, intertwined evolution of humans and microbes. They discuss how novel DNA sequencing has shed entirely new light on the complexity of microbe-human interactions, and they examine the potential benefits to human health: amazing possibilities for pinpoint treatment of infections and other illnesses without upsetting the vital balance of an individual microbiome. This book has been inspired by an exhibition, The Secret World Inside You: The Microbiome, at the American Museum of Natural History, which will open in New York in early November 2015 and run until August 2016. It will then travel to other museums in the United States and abroad.

Download or read book Amoebae as Host Models to Study the Interaction with Pathogens written by Sascha Thewes and published by Frontiers Media SA. This book was released on 2019-08-27 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human body is constantly faced with microorganisms. Most of these bacteria, fungi, and viruses are harmless, many of them are beneficial, and a small fraction is pathogenic. For humans, infection with pathogenic microorganisms can be very serious or even fatal, ranging from mild transient or chronic infections to death. The first line of defence against pathogens is our innate immune system. Beside chemical and physical defence mechanisms of the innate immune system, phagocytic cells such as macrophages play a crucial role in the fight against pathogenic microorganisms. However, phagocytic cells and pathogens are in a constant evolutionary arms race, inventing new strategies to successfully kill pathogens and learning how to resist phagocytosis and intracellular killing, respectively. If pathogens are not obligatory adapted to the human body or other animals, they also have to face environmental phagocytes in the form of amoebae. Many aspects of phagocytosis and intracellular killing are surprisingly well conserved between amoebae and macrophages. Therefore, pathogens that have evolved with environmental amoebae as their “training grounds” can also be successful during infection of macrophages and other animal phagocytic cells. In this Research Topic, we provide the latest knowledge about the potential of using amoebae as host models to study the interaction with pathogens. The Research Topic covers the interaction of amoebae with bacteria, fungi, and viruses and also illustrates the similarities and differences between amoebae and macrophages. Investigation of evolutionary conserved pathways of amoebae and macrophages furthers our understanding of the biology of host-pathogen interactions and helps to develop new anti-infection therapies.

This book was released on 2017-10-06 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: People's desire to understand the environments in which they live is a natural one. People spend most of their time in spaces and structures designed, built, and managed by humans, and it is estimated that people in developed countries now spend 90 percent of their lives indoors. As people move from homes to workplaces, traveling in cars and on transit systems, microorganisms are continually with and around them. The human-associated microbes that are shed, along with the human behaviors that affect their transport and removal, make significant contributions to the diversity of the indoor microbiome. The characteristics of "healthy" indoor environments cannot yet be defined, nor do microbial, clinical, and building researchers yet understand how to modify features of indoor environmentsâ€"such as building ventilation systems and the chemistry of building materialsâ€"in ways that would have predictable impacts on microbial communities to promote health and prevent disease. The factors that affect the environments within buildings, the ways in which building characteristics influence the composition and function of indoor microbial communities, and the ways in which these microbial communities relate to human health and well-being are extraordinarily complex and can be explored only as a dynamic, interconnected ecosystem by engaging the fields of microbial biology and ecology, chemistry, building science, and human physiology. This report reviews what is known about the intersection of these disciplines, and how new tools may facilitate advances in understanding the ecosystem of built environments, indoor microbiomes, and effects on human health and well-being. It offers a research agenda to generate the information needed so that stakeholders with an interest in understanding the impacts of built environments will be able to make more informed decisions.

Download or read book Management of Legionella in Water Systems written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2020-02-20 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Legionnaires' disease, a pneumonia caused by the Legionella bacterium, is the leading cause of reported waterborne disease outbreaks in the United States. Legionella occur naturally in water from many different environmental sources, but grow rapidly in the warm, stagnant conditions that can be found in engineered water systems such as cooling towers, building plumbing, and hot tubs. Humans are primarily exposed to Legionella through inhalation of contaminated aerosols into the respiratory system. Legionnaires' disease can be fatal, with between 3 and 33 percent of Legionella infections leading to death, and studies show the incidence of Legionnaires' disease in the United States increased five-fold from 2000 to 2017. Management of Legionella in Water Systems reviews the state of science on Legionella contamination of water systems, specifically the ecology and diagnosis. This report explores the process of transmission via water systems, quantification, prevention and control, and policy and training issues that affect the incidence of Legionnaires' disease. It also analyzes existing knowledge gaps and recommends research priorities moving forward.
Download or read book Dictyostelium written by Richard H. Kessin and published by Cambridge University Press. This book was released on 2001-01-11 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dictyostelia are soil amoebae capable of extraordinary feats of survival, motility, chemotaxis, and development. Characterised by their ability to transform from a single-celled organism into an elaborate assemblage of thousands of synchronously-moving cells, Dictyostelids are often referred to as 'social amoebae', and have been the subjects of serious study since the 1930s. Research in this area has been instrumental in understanding many problems in cellular biology. Beginning with the history of Dictyostelids and discussing each stage of their development, this book considers the evolution of this unique organism, analyses the special properties of the Dictyostelid genome, and presents in detail the methods available, at the time of the book's original publication in 2001, to manipulate their genes. Representing the synthesis of such material and with an emphasis on combining classical experiments with modern molecular findings, this book will be essential for researchers and graduates in developmental and cellular biology.

Download or read book Ending the War Metaphor written by Institute of Medicine and published by National Academies Press. This book was released on 2006-07-09 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infectious diseases have existed longer than us, as long as us, or are relatively newer than us. It may be the case that a disease has existed for many, many years but has only recently begun affecting humans. At the turn of the century the number of deaths caused by infections in the United States had been falling steadily but since the '80s has seen an increase. In the past 30 years alone 37 new pathogens have been identified as human disease threats and 12% of known human pathogens have been classified as either emerging or remerging. Whatever the story, there is currently a "war" on infectious diseases. This war is simply the systematic search for the microbial "cause" of each disease, followed by the development of antimicrobial therapies. The "war" on infectious diseases, however, must be revisited in order to develop a more realistic and detailed picture of the dynamic interactions among and between host organisms and their diverse populations of microbes. Only a fraction of these microbes are pathogens. Thus, in order to explore the crafting of a new metaphor for host-microbe relationships, and to consider how such a new perspective might inform and prioritize biomedical research, the Forum on Microbial Threats of the Institute of Medicine (IOM) convened the workshop, Ending the War Metaphor: The Changing Agenda for Unraveling the Host-Microbe Relationship on March 16-17, 2005. Workshop participants examined knowledge and approaches to learning about the bacterial inhabitants of the human gut, the best known host-microbe system, as well as findings from studies of microbial communities associated with other mammals, fish, plants, soil, and insects. The perspective adopted by this workshop is one that recognizes the breadth and diversity of host-microbe relationships beyond those relative few that result in overt disease. Included in this summary are the reports and papers of individuals participating in the Forum as well as the views of the editors.
Download or read book The Perfect Slime written by Hans-Curt Flemming and published by IWA Publishing. This book was released on 2016-09-15 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Perfect Slime presents the latest state of knowledge and all aspects of the Extracellular Polymeric Substances, (EPS) matrix – from the ecological and health to the antifouling perspectives. The book brings together all the current material in order to expand our understanding of the functions, properties and characteristics of the matrix as well as the possibilities to strengthen or weaken it. The EPS matrix represents the immediate environment in which biofilm organisms live. From their point of view, this matrix has paramount advantages. It allows them to stay together for extended periods and form synergistic microconsortia, it retains extracellular enzymes and turns the matrix into an external digestion system and it is a universal recycling yard, it protects them against desiccation, it allows for intense communication and represents a huge genetic archive. They can remodel their matrix, break free and eventually, they can use it as a nutrient source. The EPS matrix can be considered as one of the emergent properties of biofilms and are a major reason for the success of this form of life. Nevertheless, they have been termed the “black matter of biofilms” for good reasons. First of all: the isolation methods define the results. In most cases, only water soluble EPS components are investigated; insoluble ones such as cellulose or amyloids are much less included. In particular in environmental biofilms with many species, it is difficult to impossible isolate, separate the various EPS molecules they are encased in and to define which species produced which EPS. The regulation and the factors which trigger or inhibit EPS production are still very poorly understood. Furthermore: bacteria are not the only microorganisms to produce EPS. Archaea, Fungi and algae can also form EPS. This book investigates the questions, What is their composition, function, dynamics and regulation? What do they all have in common?
