Download or read book Mechanisms of antibiotic resistance written by Jun Lin and published by Frontiers Media SA. This book was released on 2015-06-01 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antibiotics represent one of the most successful forms of therapy in medicine. But the efficiency of antibiotics is compromised by the growing number of antibiotic-resistant pathogens. Antibiotic resistance, which is implicated in elevated morbidity and mortality rates as well as in the increased treatment costs, is considered to be one of the major global public health threats (www.who.int/drugresistance/en/) and the magnitude of the problem recently prompted a number of international and national bodies to take actions to protect the public (http://ec.europa.eu/dgs/health_consumer/docs/road-map-amr_en.pdf: http://www.who.int/drugresistance/amr_global_action_plan/en/; http://www.whitehouse.gov/sites/default/files/docs/carb_national_strategy.pdf). Understanding the mechanisms by which bacteria successfully defend themselves against the antibiotic assault represent the main theme of this eBook published as a Research Topic in Frontiers in Microbiology, section of Antimicrobials, Resistance, and Chemotherapy. The articles in the eBook update the reader on various aspects and mechanisms of antibiotic resistance. A better understanding of these mechanisms should facilitate the development of means to potentiate the efficacy and increase the lifespan of antibiotics while minimizing the emergence of antibiotic resistance among pathogens.

Download or read book Bacterial Adaptation to Co resistance written by Santi M. Mandal and published by Springer Nature. This book was released on 2019-11-17 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The proposed book aims to understand the mechanism of survival of microorganisms in response to chemical stress in various ecological niches that suffer direct human intervention, more so the agricultural, domestic and hospital settings. Microbicides (e.g. disinfectants, antiseptics, fungicides, algaecides, insecticides and pesticides) are used rampantly to control undesirable microbes. Insecticides and pesticides are routinely used in agriculture which directly affect the microbial population in farms, orchards and fields. Health care environments are always stressed with disinfectants and antibiotics. It is always probable that microbicide-stressed microorganisms are in a dynamic state, displaced from one niche to the other. Some soil and water borne bacteria or their resistance determinants are also getting prominence in hospital settings after suffering selective pressure from agricides. In order to reveal the survival strategies of microbicidal-resistant microbes, it is of prime importance to know the mode of action of these complete range of microbicides (agricides to antibiotics). The present book intends to address these issues. There will be several chapters dealing with tolerance and cross resistance in microbes and bacteria in particular, dwelling in various niches. Till date, there is no consensus among scientists in theorizing molecular mechanisms to explain bacterial tolerance and their cross resistance to agricides and antibiotics.
Download or read book Handbook on Antimicrobial Resistance written by Mukteswar Prasad Mothadaka and published by Springer Nature. This book was released on 2023-07-18 with total page 1098 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antimicrobial resistance (AMR) is a global public health threat. The menace of antimicrobial resistance is present across health, animal, agriculture, food, and environment sectors. It, therefore, requires an inter-disciplinary combat approach- the one health approach, envisaged by the FAO-UNEP-WHO-WOAH Quadripartite (Food and Agriculture Organization of the United Nations (FAO), the UN Environment Programme (UNEP), the World Health Organization (WHO) and the World Organisation for Animal Health (WOAH). This comprehensive reference book provides a thorough understanding of antimicrobial resistance across different sectors. It presents deep insights and gives a global perspective on antimicrobial resistance for policymakers. The book offers essential and up-to-date information that enables researchers from multiple fields to design research on antimicrobial resistance. The book discusses molecular mechanisms and antibiotic resistance genes of significant antimicrobial-resistant pathogens, regulatory frameworks available worldwide, and mitigation strategies across the sectors, including probiotics, prebiotics, antimicrobial peptides, bacteriophages, phytochemical compounds, immunostimulants, vaccines, bacteriocins, etc. It compiles essays from leading experts in the field of antimicrobial resistance research. The book is meant for students and researchers in microbiology, medical microbiology, and public health. It is also helpful for clinicians and policymakers.
Download or read book Improving Food Safety Through a One Health Approach written by Institute of Medicine and published by National Academies Press. This book was released on 2012-09-10 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Globalization of the food supply has created conditions favorable for the emergence, reemergence, and spread of food-borne pathogens-compounding the challenge of anticipating, detecting, and effectively responding to food-borne threats to health. In the United States, food-borne agents affect 1 out of 6 individuals and cause approximately 48 million illnesses, 128,000 hospitalizations, and 3,000 deaths each year. This figure likely represents just the tip of the iceberg, because it fails to account for the broad array of food-borne illnesses or for their wide-ranging repercussions for consumers, government, and the food industry-both domestically and internationally. A One Health approach to food safety may hold the promise of harnessing and integrating the expertise and resources from across the spectrum of multiple health domains including the human and veterinary medical and plant pathology communities with those of the wildlife and aquatic health and ecology communities. The IOM's Forum on Microbial Threats hosted a public workshop on December 13 and 14, 2011 that examined issues critical to the protection of the nation's food supply. The workshop explored existing knowledge and unanswered questions on the nature and extent of food-borne threats to health. Participants discussed the globalization of the U.S. food supply and the burden of illness associated with foodborne threats to health; considered the spectrum of food-borne threats as well as illustrative case studies; reviewed existing research, policies, and practices to prevent and mitigate foodborne threats; and, identified opportunities to reduce future threats to the nation's food supply through the use of a "One Health" approach to food safety. Improving Food Safety Through a One Health Approach: Workshop Summary covers the events of the workshop and explains the recommendations for future related workshops.
Download or read book Antimicrobial Resistance in the Environment written by Patricia L. Keen and published by John Wiley & Sons. This book was released on 2012-01-24 with total page 634 pages. Available in PDF, EPUB and Kindle. Book excerpt: Examines effects of the environmental distribution of antimicrobial resistance genes on human health and the ecosystem Resistance genes are everywhere in nature—in pathogens, commensals, and environmental microorganisms. This contributed work shows how the environment plays a pivotal role in the development of antimicrobial resistance traits in bacteria and the distribution of resistant microbial species, resistant genetic material, and antibiotic compounds. Readers will discover the impact of the distribution in the environment of antimicrobial resistance genes and antibiotics on both the ecosystem and human and animal health. Antimicrobial Resistance in the Environment is divided into four parts: Part I, Sources, including ecological and clinical consequences of antibiotic resistance by environmental microbes Part II, Fate, including strategies to assess and minimize the biological risk of antibiotic resistance in the environment Part III, Antimicrobial Substances and Resistance, including antibiotics in the aquatic environment Part IV, Effects and Risks, including the effect of antimicrobials used for non-human purposes on human health Recognizing the intricate links among overlapping complex systems, this book examines antimicrobial resistance using a comprehensive ecosystem approach. Moreover, the book's multidisciplinary framework applies principles of microbiology, environmental toxicology, and chemistry to assess the human and ecological risks associated with exposure to antibiotics or antibiotic resistance genes that are environmental contaminants. Each chapter has been written by one or more leading researchers in such fields as microbiology, environmental science, ecology, and toxicology. Comprehensive reference lists at the end of all chapters serve as a gateway to the primary research in the field. Presenting and analyzing the latest findings in a field of growing importance to human and environmental health, this text offers readers new insights into the role of the environment in antimicrobial resistance development, the dissemination of antimicrobial resistant genetic elements, and the transport of antibiotic resistance genes and antibiotics.

Download or read book Antibiotic Resistance written by Adriel R. Bonilla and published by Nova Biomedical Books. This book was released on 2009 with total page 554 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antibiotic resistance is the ability of a micro-organism to withstand the effects of antibiotics. There are three mechanisms that can cause antibiotic resistance: prevention of interaction of drug with target, decreased uptake due to either an increased efflux or a decreased influx of the antimicrobial agent and enzymatic modification or destruction of the compound. In the past couple years, antibiotic resistance has become an increasing public health concern. Tuberculosis, gonorrhoea, malaria and childhood ear infections are just a few of the diseases that have become hard to treat with antibiotic drugs. This book addresses the concern that over the past few years, there has been a major rise in resistance to antibiotics among gram-negative bacteria. New antibacterial drugs with novel modes of actions are urgently required in order to fight against infection. Novel antibiotics such as linezolid, carbapenem ertapenem, daptomycin and gemifloxacin are examined in this book. The genetic approaches used in risk assessment of antibiotic resistance dissemination are looked at as well. Furthermore, this book discusses the present studies on the use of veterinary antibiotics in agriculture, on the occurrence of antibiotic compounds and resistant bacteria in soil and water and clearly demonstrates the need for further studies.
Download or read book The Structure of Fitness Landscapes in Antibiotic Resistant Bacteria written by John Barrett Deris and published by . This book was released on 2013 with total page 163 pages. Available in PDF, EPUB and Kindle. Book excerpt: Antibiotic use is so ingrained in modern healthcare and agriculture that it can be difficult to imagine life in the pre-antibiotic era of the twentieth century. Many privileges we currently take for granted as rights, e.g., modern surgery, would not be possible without these drugs. But the rapid rise of antibiotic resistance may soon thrust the world back into this era. In order to predict (and ultimately prevent) the emergence of antibiotic resistance, it is crucial to establish quantitative, predictive links between the fitness of drug resistant organisms and the molecular mechanisms conferring resistance. Although the resistance mechanisms are often well characterized in vitro, their contributions to microbial fitness may depend critically on the environment and on the internal state of bacteria, which are often unknown in quantitative terms. To bridge this gap I investigate E. coli strains constitutively expressing resistance to translation-inhibiting antibiotics. The results show that in the presence of drugs, genes providing drug resistance are subject to an innate, positive feedback due to the global effect of drug-inhibited growth on gene expression. This feedback results in complex behaviors for isogenic populations of cells, including an abrupt drop in the growth rate of cultures at a threshold drug concentration. At drug concentrations below this threshold, cells exhibit growth bistability--the coexistence of large populations of non-growing cells among otherwise identical, but growing, cells. This work demonstrates for the first time that many bacteria remain susceptible to an antibiotic even as they carry resistance to it. These behaviors do not appear in strains that lack drug resistance, and a quantitative characterization of drug-drug resistance interactions reveals a whole that is surprisingly richer than its parts. A mathematical model of bacterial growth based on the innate feedback predicts the onset of bistability and the growth rates of growing sub-populations, without invoking any ad hoc fitting parameters. Furthermore, the model describes a fitness landscape for bacterial drug resistance in different environments, allowing me to characterize the factors that determine the evolvability of resistance. The approach I use can be generalized to study resistance against other classes of antibiotics, besides the translation inhibitors studied here.
Download or read book Antibiotics written by Claudio O. Gualerzi and published by John Wiley & Sons. This book was released on 2013-09-05 with total page 549 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most of the antibiotics now in use have been discovered more or less by chance, and their mechanisms of action have only been elucidated after their discovery. To meet the medical need for next-generation antibiotics, a more rational approach to antibiotic development is clearly needed. Opening with a general introduction about antimicrobial drugs, their targets and the problem of antibiotic resistance, this reference systematically covers currently known antibiotic classes, their molecular mechanisms and the targets on which they act. Novel targets such as cell signaling networks, riboswitches and bacterial chaperones are covered here, alongside the latest information on the molecular mechanisms of current blockbuster antibiotics. With its broad overview of current and future antibacterial drug development, this unique reference is essential reading for anyone involved in the development and therapeutic application of novel antibiotics.
Download or read book Antibiotics and Antibiotic Resistance in the Environment written by Carlos F. Amabile-Cuevas and published by CRC Press. This book was released on 2015-12-30 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The presence of antibiotics, antibiotic resistance genes, and antibiotic resistant bacteria in the environment is a cause of growing worldwide concern, as it reveals the extensive impact of antibiotic abuse and other human-related pressures upon microbes. The field of detecting and measuring resistance in the environment has rapidly evolved to a systematic search of organisms and genes. This book will review the available evidence and hypotheses on where antibiotic resistance is coming from and for how long it has been there. Further, it will discuss involved maintenance pressures, resistance spread, traits and laboratory and in-silico strategies to further investigate antibiotic resistance.
