FLANNERY, DEPARTMENT EDITOR I am writing this column in late August, so it's difficult to predict to antibiotics, that the reign of these drugs was likely to be short what the HI N I flu situation will be by like the time it is published lived and could only be extended by human ingenuity working towards the end of the year. Since there is already a pandemic, to keep one step ahead of the microbes.

Instead, Iwill make a prognostication that Pasteur's intellectual heritage. He came to the United States and is a safer bet: there will continue to be health issues of some kind spent most of his career as a researcher at what is now Rockefeller at the end of this year, at the end of this century, and on to the University in New York. There he discovered gramicidin, the first end of this millennium. I am using as my crystal ball a book by clinically tested antibiotic. While it didn't prove to be an effective Rene Dubos (1901-1982) called Mirage of Health (1959). It seems drug, Dubos's research did yield useful information on antibi appropriate to examine this book on the fiftieth anniversary of its otic dynamics both in culture and in living organisms. When publication, because it is at least as relevant today as itwas at the penicillin was discovered and being developed as a drug, he was time it came out. Also, since this issue of ABT is devoted to health involved in the early work done in the United States. He also did and medicine, this work is a great reminder of the limits of the research on tuberculosis and pneumonia. latter to ensure the former. It was Dubos's studies on how bacteria became resistant to The book's main argument is that, as the title suggests, the effects of antibiotics that led him to consider the theme of the quest for perfect health is an unending one, just as walking health as amirage. By this time, in addition to his journal articles, towards amirage is a fruitless task. Dubos contends that the idea Dubos had already published two books for the general reader: a that better days are coming, that ifwe get rid of the latest scourge biography of Pasteur (1950) and a book on tuberculosis (1952). to health, life will be wonderful and we will to a ripe old age in Inmidlife, he had discovered his gift for communication and went good health, just isn't going to happen.

However, Dubos looks at the other side of the coin as well Others saw illness in more specific terms, with different illnesses and examines the social and political environments which lead having different causes and resulting in different problems within to health improvements. He argues that tuberculosis, bacterial the body, what came to be called the "specific etiology" view pneumonia, and cholera had become much less lethal in the 19th of disease. This is obviously the dominant opinion in medicine century, well before the discovery of the specific etiologies of today, and Dubos traces its development and its consequences, these infections. Better sanitation and improved living conditions focusing on medical approaches to, not surprisingly, infectious were responsible for this improvement.

Pasteur and his successors were identifying specific organisms as the cause of specific kinds did a very good job of indoctrinating the public with the idea that of illnesses. But this cause-and-effect relationship was not always if the infectious agent is removed so is the disease. But itmakes clear-cut and many in the field questioned it. They argued that a big difference when that removal takes place-before or after an diseases such as tuberculosis and cholera were not the result of individual is infected.
