Download or read book Biofilm Associated Antimicrobial Resistance and Its Recovery written by Dibyajit Lahiri and published by CRC Press. This book was released on 2023-12-01 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: A biofilm is a collection of microbial cells that have adhered to biotic surfaces such as plant cuticles or animal epithelia, as well as abiotic surfaces such as rocky substratum or catheter exteriors. The life cycle of a microorganism includes the fundamental process of biofilm formation for survival in diverse and harsh environments since it is a protected mode of growth allowing colonisation of new habitats by dispersal of microbes from the microbial clusters. The biofilm bound microorganisms remain embedded in an extracellular polymeric matrix that protects the indwelling cells from surfactants, biocides, several invaders like protozoans, and defences offered by the hosts like phagocytic cells. The biofilm bound recalcitrant microbes induce chronic and nosocomial diseases, posing a serious threat to public health. It has been observed that various antimicrobial drugs are able to successfully remove the planktonic (freely suspended) states of microbes as compared to the sessile (substrate-bound) forms, thus resulting in the development of antimicrobial resistance. Modern pharmacological strategies targeting the biofilm matrix differ from the conventional methods of antibiotic usage. This includes the use of natural compounds such as plant bioactive molecules, antimicrobial peptides, green synthesised nanoparticles, or secondary metabolites from other organisms that not only prevent the rise of antimicrobial resistance but are also safe for the host tissues. Biofilm Associated Antimicrobial Resistance and Its Recovery provides a detailed and systematic review of alternative pharmacological developments in the field of biofilm research. Features: A narrative overview of the mechanism of biofilm formation and its role in the emergence of antimicrobial resistance. Recent research in the development of antibiofilm remedies involving biogenic compounds. Advancements in biofilm detection methodologies with cutting-edge technologies. This book serves as a resource for researchers who need to understand and analyze the progression of events during microbial biofilm formation, as well as design safer methodologies for its successful eradication. It may also be used as a textbook for a graduate level course in microbiology or microbial biotechnology.

Download or read book Bacterial Biofilms written by Tony Romeo and published by Springer Science & Business Media. This book was released on 2008-02-26 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout the biological world, bacteria thrive predominantly in surface-attached, matrix-enclosed, multicellular communities or biofilms, as opposed to isolated planktonic cells. This choice of lifestyle is not trivial, as it involves major shifts in the use of genetic information and cellular energy, and has profound consequences for bacterial physiology and survival. Growth within a biofilm can thwart immune function and antibiotic therapy and thereby complicate the treatment of infectious diseases, especially chronic and foreign device-associated infections. Modern studies of many important biofilms have advanced well beyond the descriptive stage, and have begun to provide molecular details of the structural, biochemical, and genetic processes that drive biofilm formation and its dispersion. There is much diversity in the details of biofilm development among various species, but there are also commonalities. In most species, environmental and nutritional conditions greatly influence biofilm development. Similar kinds of adhesive molecules often promote biofilm formation in diverse species. Signaling and regulatory processes that drive biofilm development are often conserved, especially among related bacteria. Knowledge of such processes holds great promise for efforts to control biofilm growth and combat biofilm-associated infections. This volume focuses on the biology of biofilms that affect human disease, although it is by no means comprehensive. It opens with chapters that provide the reader with current perspectives on biofilm development, physiology, environmental, and regulatory effects, the role of quorum sensing, and resistance/phenotypic persistence to antimicrobial agents during biofilm growth.

Download or read book Microbial Biofilms written by Mukesh Kumar Yadav and published by Elsevier. This book was released on 2024-04-15 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Microbial biofilms are serious problem in medical settings as they are associated with significant mortality and morbidity. Infection related to biofilms not only increases recovery time, but also escalates the cost of disease management. Biofilms are intrinsically resistant to antibiotics and evade human defense mechanisms. In addition, the close proximity of microbes within biofilms promotes genetic transformation, facilitating the acquisition of antibiotic-resistant genes and leading to an increased prevalence of diseases associated with resistance. Fortunately, with advances in science and technology, novel strategies are being utilized to mitigate the impact of biofilms on human health. Microbial Biofilms: Role in Human Infectious Diseases focuses on new and emerging concepts in microbial biofilm research. It explores topics such as the mechanisms of biofilm formation, biofilm-induced pathogenesis, biofilm detection and diagnosis, gene exchange within biofilms, strategies to control microbial biofilms, and the burden of biofilm-associated infections. Additionally, the book highlights the various antibiofilm strategies, such as surface coating, signal quenching, novel compounds that can be translated to curb biofilm-associated infections, and the escalation of antimicrobial resistance determinants.

Download or read book Biofilm Infections written by Thomas Bjarnsholt and published by Springer. This book was released on 2014-10-11 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will cover both the evidence for biofilms in many chronic bacterial infections as well as the problems facing these infections such as diagnostics and treatment regimes. A still increasing interest and emphasis on the sessile bacterial lifestyle biofilms has been seen since it was realized that that less than 0.1% of the total microbial biomass lives in the planktonic mode of growth. The term was coined in 1978 by Costerton et al. who defined the term biofilm for the first time.In 1993 the American Society for Microbiology (ASM) recognised that the biofilmmode of growth was relevant to microbiology. Lately many articles have been published on the clinical implications of bacterial biofilms. Both original articles and reviews concerning the biofilm problem are available.

This book was released on 2006-01-03 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans coexist with millions of harmless microorganisms, but emerging diseases, resistance to antibiotics, and the threat of bioterrorism are forcing scientists to look for new ways to confront the microbes that do pose a danger. This report identifies innovative approaches to the development of antimicrobial drugs and vaccines based on a greater understanding of how the human immune system interacts with both good and bad microbes. The report concludes that the development of a single superdrug to fight all infectious agents is unrealistic.

This book was released on 2011-12-30 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many potential applications of synthetic and systems biology are relevant to the challenges associated with the detection, surveillance, and responses to emerging and re-emerging infectious diseases. On March 14 and 15, 2011, the Institute of Medicine's (IOM's) Forum on Microbial Threats convened a public workshop in Washington, DC, to explore the current state of the science of synthetic biology, including its dependency on systems biology; discussed the different approaches that scientists are taking to engineer, or reengineer, biological systems; and discussed how the tools and approaches of synthetic and systems biology were being applied to mitigate the risks associated with emerging infectious diseases. The Science and Applications of Synthetic and Systems Biology is organized into sections as a topic-by-topic distillation of the presentations and discussions that took place at the workshop. Its purpose is to present information from relevant experience, to delineate a range of pivotal issues and their respective challenges, and to offer differing perspectives on the topic as discussed and described by the workshop participants. This report also includes a collection of individually authored papers and commentary.

Download or read book Antiseptic Stewardship written by Günter Kampf and published by Springer. This book was released on 2018-08-25 with total page 694 pages. Available in PDF, EPUB and Kindle. Book excerpt: Various antiseptic agents, such as chlorhexidine, are used for different applications, e.g. in healthcare, veterinary medicine, animal production and household products, including cosmetics. However, not all antiseptic agents provide significant health benefits, especially in some products used in human medicine (alcohol-based hand rubs, antimicrobial soaps). While some products (antimicrobial soaps, surface disinfectants, instrument disinfectants, wound antiseptics) may contain one or more biocidal agents with a comparable antimicrobial efficacy but large differences in their potential for microbial adaptation and tolerance. An increased bacterial resistance has been described for various antimicrobial agents, sometimes including a cross-resistance to antibiotics. The book is the first comprehensive reference resource on antiseptic agents, including their efficacy, natural and acquired resistance, adaptation, and cross-resistance. It also discusses their and appropriate use in terms of a balance between their efficacy and the risk of acquired bacterial resistance / tolerance. Focusing on human and veterinary medicine and household products, it helps readers make informed decisions concerning against antiseptic products based on their composition. The book contributes to reduce any unnecessary selection pressure towards emerging pathogens and to keep the powerful antiseptic agents for all those applications that have a clear benefit (e.g. reduction of healthcare-associated infection).

Download or read book Extending the Cure written by Ramanan Laxminarayan and published by Routledge. This book was released on 2010-09-30 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our ability to treat common bacterial infections with antibiotics goes back only 65 years. However, the authors of this report make it clear that sustaining a supply of effective and affordable antibiotics cannot be without changes to the incentives facing patients, physicians, hospitals, insurers, and pharmaceutical manufacturers. In fact, increasing resistance to these drugs is already exacting a terrible price. Every day in the United States, approximately 172 men, women, and children die from infections caused by antibiotic-resistant bacteria in hospitals alone. Beyond those deaths, antibiotic resistance is costing billions of dollars through prolonged hospital stays and the need for doctors to resort to ever more costly drugs to use as substitute treatments. Extending the Cure presents the problem of antibiotic resistance as a conflict between individual decision makers and their short-term interest and the interest of society as a whole, in both present and future: The effort that doctors make to please each patient by prescribing a drug when it might not be properly indicated, poor monitoring of discharged patients to ensure that they do not transmit drug-resistant pathogens to other persons, excesses in the marketing of new antibiotics, and the broad overuse of antibiotics all contribute to the development and spread of antibiotic-resistant bacteria. The book explores a range of policy options that would encourage patients, health care providers, and managed care organizations to serve as more responsible stewards of existing antibiotics as well as proposals that would give pharmaceutical firms greater incentives to develop new antibiotics and avoid overselling. If the problem continues unaddressed, antibiotic resistance has the potential to derail the health care system and return us to a world where people of all ages routinely die from simple infections. As a basis for future research and a spur to a critically important dialogue, Extending the Cure is a fundamental first step in addressing this public health crisis. The Extending the Cure project is funded in part by the Robert Wood Johnson Foundation through its Pioneer Portfolio.
