Viruses Vs. Superbugs by T. Häusler,Thomas Häusler Pdf
Each year thousands of people die from bacteria resistant to antibiotics. Alternative drugs are urgently needed. A surprising ray of hope from the past are viruses that kill bacteria, but not us. Award-winning science journalist Thomas Häusler investigates how these long-forgotten cures may help sick people today.
In the US alone some 90,000 people die from superbugs--bacteria that have grown immune to antibiotics. Officials agree that this problem will only get worse with time and new alternatives must be found. One alternative that is being considered by scientists is a kind of virus called a bacteriophage. "Phages"--viruses that kill bacteria but not humans--were discovered in 1915. Phage therapy was successfully used for twenty years before the invention of penicillin made them obsolete everywhere but Eastern Europe, where they are still in use today. In its first English translation, this book tells the fascinating story behind the history of the phage, its discovery and development, as well as the strides that are being made to bring the therapy back to the West today.
The Perfect Predator by Steffanie Strathdee,Thomas Patterson Pdf
An electrifying memoir of one woman's extraordinary effort to save her husband's life-and the discovery of a forgotten cure that has the potential to save millions more. "A memoir that reads like a thriller." -New York Times Book Review "A fascinating and terrifying peek into the devastating outcomes of antibiotic misuse-and what happens when standard health care falls short." -Scientific American Epidemiologist Steffanie Strathdee and her husband, psychologist Tom Patterson, were vacationing in Egypt when Tom came down with a stomach bug. What at first seemed like a case of food poisoning quickly turned critical, and by the time Tom had been transferred via emergency medevac to the world-class medical center at UC San Diego, where both he and Steffanie worked, blood work revealed why modern medicine was failing: Tom was fighting one of the most dangerous, antibiotic-resistant bacteria in the world. Frantic, Steffanie combed through research old and new and came across phage therapy: the idea that the right virus, aka "the perfect predator," can kill even the most lethal bacteria. Phage treatment had fallen out of favor almost 100 years ago, after antibiotic use went mainstream. Now, with time running out, Steffanie appealed to phage researchers all over the world for help. She found allies at the FDA, researchers from Texas A&M, and a clandestine Navy biomedical center -- and together they resurrected a forgotten cure. A nail-biting medical mystery, The Perfect Predator is a story of love and survival against all odds, and the (re)discovery of a powerful new weapon in the global superbug crisis.
International Bestseller "An amazing, informative book that changes our perspective on medicine, microbes and our future." --Siddhartha Mukherjee, MD, New York Times bestselling author of The Emperor of All Maladies A New York Times bestselling author shares this exhilarating story of cutting-edge science and the race against the clock to find new treatments in the fight against the antibiotic-resistant bacteria known as superbugs. Physician, researcher, and ethics professor Matt McCarthy is on the front lines of a groundbreaking clinical trial testing a new antibiotic to fight lethal superbugs, bacteria that have built up resistance to the life-saving drugs in our rapidly dwindling arsenal. This trial serves as the backdrop for the compulsively readable Superbugs, and the results will impact nothing less than the future of humanity. Dr. McCarthy explores the history of bacteria and antibiotics, from Alexander Fleming's discovery of penicillin, to obscure sources of innovative new medicines (often found in soil samples), to the cutting-edge DNA manipulation known as CRISPR, bringing to light how we arrived at this juncture of both incredible breakthrough and extreme vulnerability. We also meet the patients whose lives are hanging in the balance, from Remy, a teenager with a dangerous and rare infection, to Donny, a retired New York City firefighter with a compromised immune system, and many more. The proverbial ticking clock will keep readers on the edge of their seats. Can Dr. McCarthy save the lives of his patients infected with the deadly bacteria, who have otherwise lost all hope?
Superbugs, bacterial infections and diseases that have become immune to current antibiotics, are becoming more common. What makes a superbug and why are they becoming more frequent? Is there anything we can do to protect ourselves from superbugs? This exciting book answers these questions and more!
Award-winning Boston University educator and researcher Muhammad H. Zaman provides a chilling look at the rise of antibiotic-resistant superbugs, explaining how we got here and what we must do to address this growing global health crisis. In September 2016, a woman in Nevada became the first known case in the U.S. of a person who died of an infection resistant to every antibiotic available. Her death is the worst nightmare of infectious disease doctors and public health professionals. While bacteria live within us and are essential for our health, some strains can kill us. As bacteria continue to mutate, becoming increasingly resistant to known antibiotics, we are likely to face a public health crisis of unimaginable proportions. “It will be like the great plague of the middle ages, the influenza pandemic of 1918, the AIDS crisis of the 1990s, and the Ebola epidemic of 2014 all combined into a single threat,” Muhammad H. Zaman warns. The Biography of Resistance is Zaman’s riveting and timely look at why and how microbes are becoming superbugs. It is a story of science and evolution that looks to history, culture, attitudes and our own individual choices and collective human behavior. Following the trail of resistant bacteria from previously uncontacted tribes in the Amazon to the isolated islands in the Arctic, from the urban slums of Karachi to the wilderness of the Australian outback, Zaman examines the myriad factors contributing to this unfolding health crisis—including war, greed, natural disasters, and germophobia—to the culprits driving it: pharmaceutical companies, farmers, industrialists, doctors, governments, and ordinary people, all whose choices are pushing us closer to catastrophe. Joining the ranks of acclaimed works like Microbe Hunters, The Emperor of All Maladies, and Spillover, A Biography of Resistance is a riveting and chilling tale from a natural storyteller on the front lines, and a clarion call to address the biggest public health threat of our time.
What Is Phage Therapy The therapeutic use of bacteriophages, also known as phage therapy, viral phage therapy, or phagotherapy, may be defined as the treatment of infectious diseases caused by harmful bacteria. This treatment technique arose at the beginning of the 20th century, but following the second world war, it was gradually supplanted by the use of antibiotics in most areas of the globe. Bacteriophages are a kind of virus that attach itself to bacterial cells and then inject their genome into the bacterial cell. Bacteriophages are also known as phages. The bacterial genome is successfully replaced by the genome of the virus, which results in the cessation of the bacterial infection. Because it is unable to replicate, the bacterial cell that is responsible for the infection instead creates extra phages. Phages are only effective against extremely specific bacterial species due to their high level of specificity.

This book fills a void. Never before has a comprehensive history of phage therapy—a once-neglected, now resurgent field—been written. Kuchment writes from the perspective of the eager student of history for the common reader.
While viruses—the world’s most abundant biological entities—are not technically alive, they invade, replicate, and evolve within living cells. Michael Cordingley goes beyond our familiarity with infections to show how viruses spur evolutionary change in their hosts and shape global ecosystems, from ocean photosynthesis to drug-resistant bacteria.
How to Fight Harmful Microbial Bugs and Superbugs? by Alain Fischer,Michel Goldman,Paul-Henri Lambert Pdf
The evolution of human beings has been shaped to a large extent by microbes. A number of microbes are innocuous or even contribute to our health equilibrium. This is the case of bacteria and viral phages present in our gut. However, several bacteria, viruses, parasites, and fungi are damaging our bodies, causing a number of acute and chronic diseases. Until recently, these bugs represented the main causes of death. Better hygiene, vaccines, antibiotics and other anti-microbial drugs have resulted in a better control or cure of many infections. However, malaria, tuberculosis, and AIDS still represent major threats in several countries and the recent epidemics of Ebola and Zika demonstrate how vulnerable we are to newly emerging viruses. Furthermore, diarrhea and pneumonia caused by bacteria or viruses still kill millions of children worldwide. Most importantly, bacteria resistant to existing antibiotics are multiplying at a high pace and these superbugs are expected to kill more and more people in the coming years. Clearly, we need to develop more effective approaches to tackle bugs and superbugs. Better hygiene and better vaccine coverage must be considered first and education of kids is essential in this respect. This is the main objective of this series of papers published in Frontiers for Young Minds under the heading “How to Fight Harmful Microbial Bugs and Superbugs?”. Another key objective of the collection is to elicit the interest of children for research on innovative anti-microbial therapies and vaccines.
Evolving germs – Antibiotic resistance and natural selection in education and public communication by Gustav Bohlin Pdf
Bacterial resistance to antibiotics threatens modern healthcare on a global scale. Several actors in society, including the general public, must become more involved if this development is to be countered. The conveyance of relevant information provided through education and media reports is therefore of high concern. Antibiotic resistance evolves through the mechanisms of natural selection; in this way, a sound understanding of these mechanisms underlies explanations of causes and the development of effective risk-reduction measures. In addition to natural selection functioning as an explanatory framework to antibiotic resistance, bacterial resistance as a context seems to possess a number of qualities that make it suitable for teaching natural selection – a subject that has been proven notoriously hard to teach and learn. A recently suggested approach for learning natural selection involves so-called threshold concepts, which encompass abstract and integrative ideas. The threshold concepts associated with natural selection include, among others, the notions of randomness as well as vast spatial and temporal scales. Illustrating complex relationships between concepts on different levels of organization is one, of several, areas where visualizations are efficient. Given the often-imperceptible nature of threshold concepts as well as the fact that natural selection processes occur on different organizational levels, visual accounts of natural selection have many potential benefits for learning. Against this background, the present dissertation explores information conveyed to the public regarding antibiotic resistance and natural selection, as well as investigates how these topics are presented together, by scrutinizing media including news reports, websites, educational textbooks and online videos. The principal method employed in the media studies was content analysis, which was complemented with various other analytical procedures. Moreover, a classroom study was performed, in which novice pupils worked with a series of animations explaining the evolution of antibiotic resistance. Data from individual written assignments, group questions and video-recorded discussions were collected and analyzed to empirically explore the potential of antibiotic resistance as a context for learning about evolution through natural selection. Among the findings are that certain information, that is crucial for the public to know, about antibiotic resistance was conveyed to a low extent through wide-reaching news reporting. Moreover, explanations based on natural selection were rarely included in accounts of antibiotic resistance in any of the examined media. Thus, it is highly likely that a large proportion of the population is never exposed to explanations for resistance development during education or through newspapers. Furthermore, the few examples that were encountered in newspapers or textbooks were hardly ever visualized, but presented only in textual form. With regard to videos purporting to explain natural selection, it was found that a majority lacked accounts of central key concepts. Additionally, explanations of how variation originates on the DNA-level were especially scarce. These and other findings coming from the content analyses are discussed through the lens of scientific literacy and could be used to inform and strengthen teaching and scientific curricula with regards to both antibiotic resistance and evolution. Furthermore, several factors of interest for using antibiotic resistance in the teaching of evolution were identified from the classroom study. These involve, among others, how learners’ perception of threshold concepts such as randomness and levels of organization in space and time are affected by the bacterial context
