Mechanisms of antibiotic resistance


Book Description

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.







Challenges to Tackling Antimicrobial Resistance


Book Description

An accessible overview of the challenges in tackling AMR, and the economic and policy responses of the 'One Health' approach. It will appeal to policy-makers seeking to strengthen national and local polices tackling AMR, as well as students and academics who want an overview of the latest scientific evidence regarding effective AMR policies.




E. Coli Infections


Book Description

Gram-negative Escherichia coli (E. coli) bacteria are the most numerous commensal aerobic germs located in the human colon. Diarrhea caused by E. coli pathogenic strains is a major cause of death in developing countries, especially the sub-Saharan and South Asian areas. Some strains cause diarrhea, and all of them may produce an infectious disease. This book includes ten chapters covering the main aspects of infections related to E. coli, their pathogenic mechanisms, treatments, and resistance to diverse antibiotics.




Antimicrobial Resistance


Book Description

Tackling the realities of the antimicrobial resistance (AMR) situation today is no longer uncommon. Many battles have been fought in the past since the discovery of antibiotics between man and microbes. In the tussle of new antibiotic modifications, the transmission of resistant genes, both vertically and horizontally unveils yet another resistant attribute for the microbe, for it only to be faced with a more powerful, wide spectrum antibiotic; the cycle continues-and the winner is yet to be known. This book aims to provide some insight into various molecular mechanisms, agricultural mitigation methods, and the One Health applications to maybe, just maybe, tip the scales towards us.




Urinary Tract Infections


Book Description

A comprehensive overview of clinically important infections of the urinary tract Urinary tract infections (UTIs) continue to rank among the most common infectious diseases of humans, despite remarkable progress in the ability to detect and treat them. Recurrent UTIs are a continuing problem and represent a clear threat as antibiotic-resistant organisms and infection-prone populations grow. Urinary Tract Infections: Molecular Pathogenesis and Clinical Management brings the scientific community up to date on the research related to these infections that has occurred in the nearly two decades since the first edition. The editors have assembled a team of leading experts to cover critical topics in these main areas: clinical aspects of urinary tract infections, including anatomy, diagnosis, and management, featuring chapters on the vaginal microbiome as well as asymptomatic bacteriuria, prostatitis, and urosepsis the origins and virulence mechanisms of the bacteria responsible for most UTIs, including uropathogenic Escherichia coli, Proteus mirabilis, and Klebsiella pneumoniae the host immune response to UTIs, the rise of antibiotic-resistant strains, and the future of therapeutics This essential reference serves as both a resource and a stimulus for future research endeavors for anyone with an interest in understanding these important infections, from the classroom to the laboratory and the clinic.

Microbial Virulence Factors


Book Description

Microbial virulence factors encompass a wide range of molecules produced by pathogenic microorganisms, enhancing their ability to evade their host defenses and cause disease. This broad definition comprises secreted products such as toxins, enzymes, exopolysaccharides, as well as cell surface structures such as capsules, lipopolysaccharides, glyco- and lipoproteins. Intracellular changes in metabolic regulatory networks, governed by protein sensors/regulators and non-coding regulatory RNAs, are also known to contribute to virulence. Furthermore, some secreted microbial products have the ability to enter the host cell and manipulate their machinery, contributing to the success of the infection. The knowledge, at the molecular level, of the biology of microbial pathogens and their virulence factors is central in the development of novel therapeutic molecules and strategies to combat microbial infections. The present collection comprises state of the art research and review papers on virulence factors and mechanisms of a wide range of bacterial and fungal pathogens for humans, animals, and plants, thus reflecting the impact of microorganisms in health and economic human activities, and the importance of the topic.




Global Antimicrobial Resistance Surveillance System


Book Description

"In May 2015, the Sixty-eighth World Health Assembly adopted the Global action plan on antimicrobial resistance, which reflects the global consensus that AMR poses a profound threat to human health. One of the five strategic objectives of the Global action plan is to strengthen the evidence base through enhanced global surveillance and research. The Global Antimicrobial Resistance Surveillance System (GLASS) has been developed to facilitate and encourage a standardized approach to AMR surveillance globally and in turn support the implementation of the Global action plan on antimicrobial resistance. This manual addresses the early phase of implementation of GLASS, focussing on surveillance of resistance in common human bacterial pathogens. The intended readership of this publication is public health professionals and health authorities responsible for national AMR surveillance. It outlines the GLASS standards and describes the road map for implementation of the system between 2015 and 2019. Further development of GLASS will be based on the lessons learnt during this period"--Publisher's description.




Microbiology of Waterborne Diseases


Book Description

The second edition of Microbiology of Waterborne Diseases describes the diseases associated with water, their causative agents and the ways in which they gain access to water systems. The book is divided into sections covering bacteria, protozoa, and viruses. Other sections detail methods for detecting and identifying waterborne microorganisms, and the ways in which they are removed from water, including chlorine, ozone, and ultraviolet disinfection. The second edition of this handbook has been updated with information on biofilms and antimicrobial resistance. The impact of global warming and climate change phenomena on waterborne illnesses are also discussed. This book serves as an indispensable reference for public health microbiologists, water utility scientists, research water pollution microbiologists environmental health officers, consultants in communicable disease control and microbial water pollution students. Focuses on the microorganisms of most significance to public health, including E. coli, cryptosporidium, and enterovirus Highlights the basic microbiology, clinical features, survival in the environment, and gives a risk assessment for each pathogen Contains new material on antimicrobial resistance and biofilms Covers drinking water and both marine and freshwater recreational bathing waters
