Antibiotic Resistance: Origins, Evolution, Selection and Spread Chairman: Stuart B. Levy, 1997 Over the last 50 years, the rapid increase in the use of antibiotics, not only in people, but also in animal husbandry and agriculture, has delivered a selection unprecedented in the history of evolution. Consequently, society is facing one of its gravest public health problems-the emergence of infectious bacteria with resistance to many, and in some cases all, available antibiotics. This book brings together a multidisciplinary group of experts to discuss this problem. It begins by examining the origins of resistance and goes on to look at how the use of antibiotics in human medicine and farming/agriculture has selected for resistant bacteria. Separate chapters describe the evolution of resistance determinants and how these are spread both within and between bacterial species. Finally, the book contains discussions on strategies for countering the threat of antibiotic resistance. A major re-thinking of our approach to the treatment of infectious diseases is proposed-that antibiotic resistance should be seen as a problem created by the disruption of normal microbial ecology. To restore efficacy to earlier antibiotics, and to maintain the success of new antibiotics that are introduced, we need to use these drugs in a way that ensures an ecological balance that favours the predominance of susceptible bacteria.

The Antibiotic Era

Reform, Resistance, and the Pursuit of a Rational Therapeutics

In The Antibiotic Era, physician-historian Scott H. Podolsky narrates the far-reaching history of antibiotics, focusing particularly on reform efforts that attempted to fundamentally change how antibiotics are developed and prescribed. This sweeping chronicle reveals the struggles faced by crusading reformers from the 1940s onward as they advocated for a rational therapeutics at the crowded intersection of bugs and drugs, patients and doctors, industry and medical academia, and government and the media. During the post–World War II "wonder drug" revolution, antibiotics were viewed as a panacea for mastering infectious disease. But from the beginning, critics raised concerns about irrational usage and overprescription. The first generation of antibiotic reformers focused on regulating the drug industry. The reforms they set in motion included the adoption of controlled clinical trials as the ultimate arbiters of therapeutic efficacy, the passage of the Kefauver-Harris amendments mandating proof of drug efficacy via well-controlled studies, and the empowering of the Food and Drug Administration to remove inefficacious drugs from the market. Despite such victories, no entity was empowered to rein in physicians who inappropriately prescribed, or overly prescribed, approved drugs. Now, in an era of emerging bugs and receding drugs, discussions of antibiotic resistance focus on the need to develop novel antibiotics and the need for more appropriate prescription practices in the face of pharmaceutical marketing, pressure from patients, and the structural constraints that impede rational delivery of antibiotics worldwide. Concerns about the enduring utility of antibiotics—indeed, about a post-antibiotic era—are widespread, as evidenced by reports from the Centers for Disease Control and Prevention, academia, and popular media alike. Only by understanding the historical forces that have shaped our current situation, Podolsky argues, can we properly understand and frame our choices moving forward.

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.

Antimicrobial therapy is a key factor in our success against pathogens poised to ravage at risk or infected individuals. However, we are currently at a watershed point as we face a growing crisis of antibiotic resistance among diverse pathogens. One area of intense interest is the impact of the application of antibiotics for uses other than the treatment of patients and the association with such utilization with emerging drug resistance. This Research Topic “Low- dose antibiotics: current status and outlook for the future” in Frontiers in Microbiology: Antimicrobials, Resistance and Chemotherapy details various aspects of the wide ranging effects of antimicrobial therapy from areas such as the regulation of host responses to modulation of bacterial virulence factors to acquisition of antibiotic resistance genes.

"What is antibiotic resistance, and why should I be concerned with it?" Media coverage and political and scientific discussions about "superbugs" that defy our current treatments, genetically–modified foods in our fields and grocery stores, the threat of bioterrorism, and the use of antibiotics in agriculture have increased citizen awareness and fears regarding the issues surrounding antibiotic resistance. Revenge of the Microbes: How Bacterial Resistance Is Undermining the Antibiotic Miracle is a single source of answers to this and other questions average people are asking. Written by experts with extensive experience in the field, Revenge of the Microbes provides the scientific information readers will need to form opinions and make informed decisions regarding the use of antibiotics. The authors have carefully sifted through a vast amount of information to ensure comprehensive coverage of topics including the larger issues of economics, politics, health, safety, and the environment. Specific antibiotics and controversies are examined in a real–life context; accounts of positions on all sides of the public policy debate are presented; and less common issues such as what happens to antibiotics once they are released into the environment, are addressed. The evolution of antibiotic–resistant bacteria is put into perspective and bacterial mutation and horizontal gene transfer are explained in simple terms. An in–depth documentation of antibiotic structures is provided in the appendix. Reader–friendly and comprehensible, Revenge of the Microbes will engage a diverse audience, including biologists, doctors, teachers, students, lawyers, environmentalists, and everyday citizens. This new volume encourages readers to consider the extensive role of antibiotics in modern medicine and the potentially catastrophic impact the loss of effective antibiotics would have today and on future generations.

Avoiding infection has always been expensive. Some human populations escaped tropical infections by migrating into cold climates but then had to procure fuel, warm clothing, durable housing, and crops from a short growing season. Waterborne infections were averted by owning your own well or supporting a community reservoir. Everyone got vaccines in rich countries, while people in others got them later if at all. Antimicrobial agents seemed at first to be an exception. They did not need to be delivered through a cold chain and to everyone, as vaccines did. They had to be given only to infected patients and often then as relatively cheap injectables or pills off a shelf for only a few days to get astonishing cures. Antimicrobials not only were better than most other innovations but also reached more of the world’s people sooner. The problem appeared later. After each new antimicrobial became widely used, genes expressing resistance to it began to emerge and spread through bacterial populations. Patients infected with bacteria expressing such resistance genes then failed treatment and remained infected or died. Growing resistance to antimicrobial agents began to take away more and more of the cures that the agents had brought.
