Book Synopsis Dormancy and Low Growth States in Microbial Disease by : Anthony R. M. Coates
Download or read book Dormancy and Low Growth States in Microbial Disease written by Anthony R. M. Coates and published by Cambridge University Press. This book was released on 2003-06-02 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: All cellular life-forms can exist in replicating and non-replicating states. Organisms replicate only when the conditions are beneficial, and when not replicating they concentrate on survival of these environmental stresses. Many bacteria, harmful to humans, survive the period of infection in a low growth state. This 2003 book addresses the basic science of microbial dormancy and low growth states, putting this in the context of human medicine. Such fundamental topics as bacterial growth and non-growth, culturability and viability are covered, as well as survival of the host's immune response, and inter-bacterial signalling. Following this introduction, more medically focused topics are discussed, namely antibiotic resistance arising during stationary phase, biofilms, the bacteria which cause gastric ulcers and tuberculosis as the classic persistent bacterial infection. This book will interest graduate students and researchers in medical microbiology, immunology and infectious disease medicine who are interested in bacterial dormancy in relation to disease.

Book Synopsis Survival of Microorganisms and Bacterial Predation and Competition in Nature by : L. E Casida (Jr)
Download or read book Survival of Microorganisms and Bacterial Predation and Competition in Nature written by L. E Casida (Jr) and published by . This book was released on 1990 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: In general, both predator and prey bacterial species in soil are dormant much of the time. This seems to be a means of avoiding starvation, desiccation, and predation. For many species of soil bacteria, the breaking of dormancy is controlled by small amounts of either magnesium or copper. The cells need the metal to allow breaking of dormancy. However, there usually isn't enough of the respective metal that is readily available in the environment. Therefore, the cells produce a specific peptide growth initiation factor (GIF) which chelates the respective metal (scavenges if from the environment) to make it available to the cells. The cells then break dormancy and start growth. The cells do not need the GIF for their growth, however: only to initiate growth. Keywords: Soil bacteria, Microorganisms, Bacterial predation, Predator bacterial species, Prey bacterial species. (JES).

Book Synopsis Dormancy and Resistance in Harsh Environments by : Esther Lubzens
Download or read book Dormancy and Resistance in Harsh Environments written by Esther Lubzens and published by Springer. This book was released on 2010-11-04 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many organisms have evolved the ability to enter into and revive from a dormant state. They can survive for long periods in this state (often even months to years), yet can become responsive again within minutes or hours. This is often, but not necessarily, associated with desiccation. Preserving one’s body and reviving it in future generations is a dream of mankind. To date, however, we have failed to learn how cells, tissues or entire organisms can be made dormant or be effectively revived at ambient temperatures. In this book studies on organisms, ranging from aquatic cyanobacteria that produce akinetes to hibernating mammals, are presented, and reveal common but also divergent physiological and molecular pathways for surviving in a dormant form or for tolerating harsh environments. Attempting to learn the functions associated with dormancy and how they are regulated is one of the great future challenges. Its relevance to the preservation of cells and tissues is one of the key concerns of this book.
Book Synopsis Stress-Induced Mutagenesis by : David Mittelman
Download or read book Stress-Induced Mutagenesis written by David Mittelman and published by Springer Science & Business Media. This book was released on 2013-03-12 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of stress-induced mutagenesis has changed ideas about mutation and evolution, and revealed mutagenic programs that differ from standard spontaneous mutagenesis in rapidly proliferating cells. The stress-induced mutations occur during growth-limiting stress, and can include adaptive mutations that allow growth in the otherwise growth-limiting environment. The stress responses increase mutagenesis specifically when cells are maladapted to their environments, i.e. are stressed, potentially accelerating evolution then. The mutation mechanism also includes temporary suspension of post-synthesis mismatch repair, resembling mutagenesis characteristic of some cancers. Stress-induced mutation mechanisms may provide important models for genome instability underlying some cancers and genetic diseases, resistance to chemotherapeutic and antibiotic drugs, pathogenicity of microbes, and many other important evolutionary processes. This book covers pathways of stress-induced mutagenesis in all systems. The principle focus is mammalian systems, but much of what is known of these pathways comes from non-mammalian systems.

Book Synopsis Hypersaline Lake Environments Exhibit Reduced Microbial Dormancy by : Joshua Christopher Vert
Download or read book Hypersaline Lake Environments Exhibit Reduced Microbial Dormancy written by Joshua Christopher Vert and published by . This book was released on 2013 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: From acid seeps and deep-sea thermal vents to glacial ice and hypersaline lakes, extreme environments contain relatively simplified communities consisting of extremophiles that have evolved to survive and thrive under adverse abiotic conditions. In more neutral environments, microorganisms use dormancy as a common life history strategy to weather temporal fluctuations of resources or stresses until more 'optimal' conditions are present. It is unclear if dormancy is an essential survival mechanism for microorganisms in extreme environments; however, recent studies suggest that extreme environments may create stable conditions for extremophiles to the extent that dormancy is of less ecological importance. Using lake salinity levels as measurements of "extreme," we evaluated the dormancy of bacterial and archaeal phyla and lake chemistry in five hypersaline and five freshwater lakes across the western United States. Dormancy was calculated using targeted metagenomics to analyze 16S rDNA and rRNA tag sequences. It was hypothesized that bacteria and archaea in hypersaline lake communities would exhibit lower levels dormancy than bacterial and archaeal communities in geologically similar freshwater lake controls. It was also hypothesized that microbial dormancy would decrease as the dominant extreme environmental variable increased in the lakes. As hypothesized, overall dormancy decreased at least 2-fold in hypersaline compared to freshwater lakes for both bacteria and archaea. Of the predominant phyla and subclasses, Firmicutes, Bacteroidetes, and Gammaproteobacteria each demonstrated at least a seven-fold decrease in dormancy in hypersaline lakes compared to freshwater lakes. Specifically, species within the genus Clostridium were responsible for 85% of the dormancy observed in the phylum Firmicutes. Also as hypothesized, microbial dormancy decreased as salinity increased in lakes. Lower dormancy in hypersaline lakes correlated with increasing salinity while lower dormancy in freshwater lakes correlated with increasing total phosphorus levels. These results suggest that dormancy is a less common life history strategy for microorganisms in extreme environments; it is proposed that this is due to the relatively stable environment in hypersaline lakes and the reduced number of available microbial niches. These results also suggest that the dominant extreme stress (i.e., salinity) may override other driving factors in an environment to ultimately determine microbial community composition, diversity and richness.

Book Synopsis Survival Strategies of Annual Desert Plants by : Yitzchak Gutterman
Download or read book Survival Strategies of Annual Desert Plants written by Yitzchak Gutterman and published by Springer Science & Business Media. This book was released on 2002-08-28 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annual desert plant species of unrelated taxa in the Negev Desert of Israel have developed complementary sets of adaptations and survival strategies as ecological equivalents with physiological, morphological and anatomical resemblances, in the various stages of their life cycles. After 40 years of research in hot deserts Yitzchak Gutterman provides a comprehensive treatise of such adaptations and strategies. In doing so he covers the following topics: post-maturation primary seed dormancy, which prevents germination of maturing seeds before the summer; seed dispersal mechanisms with escape or protection strategies; cautious or opportunistic germination strategies; seedling drought tolerance. The day-length is an important factor in regulating flowering as well as the phenotypic plasticity of seed germination which is also affected by maternal factors.

Book Synopsis Microbial Threats to Health by : Institute of Medicine
Download or read book Microbial Threats to Health written by Institute of Medicine and published by National Academies Press. This book was released on 2003-08-25 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Infectious diseases are a global hazard that puts every nation and every person at risk. The recent SARS outbreak is a prime example. Knowing neither geographic nor political borders, often arriving silently and lethally, microbial pathogens constitute a grave threat to the health of humans. Indeed, a majority of countries recently identified the spread of infectious disease as the greatest global problem they confront. Throughout history, humans have struggled to control both the causes and consequences of infectious diseases and we will continue to do so into the foreseeable future. Following up on a high-profile 1992 report from the Institute of Medicine, Microbial Threats to Health examines the current state of knowledge and policy pertaining to emerging and re-emerging infectious diseases from around the globe. It examines the spectrum of microbial threats, factors in disease emergence, and the ultimate capacity of the United States to meet the challenges posed by microbial threats to human health. From the impact of war or technology on disease emergence to the development of enhanced disease surveillance and vaccine strategies, Microbial Threats to Health contains valuable information for researchers, students, health care providers, policymakers, public health officials. and the interested public.
