The Microbial State

For three centuries, concepts of the state have been animated by one of the most powerful metaphors in politics: the body politic, a claustrophobic and bounded image of sovereignty. Climate change, neoliberalism, mass migration, and other aspects of the late Anthropocene have increasingly revealed the limitations of this metaphor. Just as the human body is not whole and separate from other bodies—comprising microbes, bacteria, water, and radioactive isotopes—Stefanie R. Fishel argues that the body politic of the state exists in dense entanglement with other communities and forms of life. Drawing on insights from continental philosophy, science and technology studies, and international relations theory, this path-breaking book critiques the concept of the body politic on the grounds of its very materiality. Fishel both redefines and extends the metaphor of the body politic and its role in understanding an increasingly posthuman, globalized world politics. By conceiving of bodies and states as lively vessels, living harmoniously with multiplicity and the biosphere, she argues that a radical shift in metaphors can challenge a politics based on fear to open new forms of global political practice and community. Reframing the concept of the body politic to accommodate greater levels of complexity, Fishel suggests, will result in new configurations for the political and social organization necessary to build a world in which the planet’s inhabitants do not merely live but actively thrive.

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.

With the application of new analytical techniques, the field of food fermentation has grown in recent years. This book provides the latest information and relevant advances on the microbial ecology of fermented foods and the application of molecular methods. This book serves as a guide for students and researchers on the most advanced techniques to identify bacteria and helps in choosing the most appropriate tools to study fermented food from a microbiological point of view.

In the past 15 years, there has been steady growth in work relating to the microbial iron cycle. It is now well established that in anaerobic environments coupling of organic matter utilization to Fe reduction is a major pathway for anaerobic respiration. In iron-rich circumneutral environments that exist at oxic-anoxic boundaries, significant progress has been made in demonstrating that unique groups of microbes can grow either aerobically or anaerobically using Fe as a primary energy source. Likewise, in high iron acidic environments, progress has been made in the study of communities of microbes that oxidize iron, and in understanding the details of how certain of these organisms gain energy from Fe-oxidation. On the iron scarcity side, it is now appreciated that in large areas of the open ocean Fe is a key limiting nutrient; thus, a great deal of research is going into understanding the strategies microbial cells, principally phytoplankton, use to acquire iron, and how the iron cycle may impact other nutrient cycles. Finally, due to its abundance, iron has played an important role in the evolution of Earth’s primary biogeochemical cycles through time. The aim of this Research Topic is to gather contributions from scientists working in diverse disciplines who have common interests in iron cycling at the process level, and at the organismal level, both from the perspective of Fe as an energy source, or as a limiting nutrient for primary productivity in the ocean. The range of disciplines may include: geomicrobiologists, microbial ecologists, microbial physiologists, biological oceanographers, and biogeochemists. Articles can be original research, techniques, reviews, or synthesis papers. An overarching goal is to demonstrate the environmental breadth of the iron cycle, and foster understanding between different scientific communities who may not always be aware of one another’s work.

The newly revised and updated third edition of the bestselling book on microbial ecology in the oceans The third edition of Microbial Ecology of the Oceans features new topics, as well as different approaches to subjects dealt with in previous editions. The book starts out with a general introduction to the changes in the field, as well as looking at the prospects for the coming years. Chapters cover ecology, diversity, and function of microbes, and of microbial genes in the ocean. The biology and ecology of some model organisms, and how we can model the whole of the marine microbes, are dealt with, and some of the trophic roles that have changed in the last years are discussed. Finally, the role of microbes in the oceanic P cycle are presented.

Inhibition and Destruction of the Microbial Cell focuses on the effects of various classes of toxic chemical agents on microbial cell. This book is organized into 14 chapters that cover the topics from two points of view: the agent and the target (the microbial cell). The introductory chapters are devoted to the inhibitory effects of elevating temperature and to the lethal effect of environmental thermal energy supply restriction on growing bacteria. A chapter focuses on the effect of various classes of antibacterial compounds, such as 4-amino-quinaldinium and 8-hydroxyquinoline derivatives, chlorhexidine, amidines, halogens, dyes, and nitrofurans. The subsequent chapters examine the effects of other chemical agents on microorganisms, including toxic gases, solutes, ions, and radiations. The book goes on examining the inhibition and destruction of specific microorganisms, such as Pseudomonas aeruginosa, Enterobacteriaceae, Mycobacteria, Cocci, bacterial spores, molds, yeasts, and viruses. The last chapter discusses the effect of the cultural prehistory of microorganisms upon their response to inhibition and destruction. This book is an invaluable resource for graduate research workers and scientists in pure and applied microbiology. This will also be a good reference for undergraduates reading specialized courses at honors level in microbiology or applied courses in food science and agriculture. Furthermore, it will be of interest to the medical profession, especially those involved in public health and pathology, as well as to scientists in the pharmaceutical industry.
