Bacteria are wondrous critters. They fix nitrogen in the soil to nourish plants, populate our intestinal tract so we can digest our food, and convert our milk into cheese. Yet, like the uncounted billions of stars in the night sky, their cosmos is vast and mysterious beyond our reckoning. They populate every nook and cranny of Mother Gaia, from the highest peaks of the Himalayas to the most abysmal depths of the ocean trenches to deep into the core of the Earth. They even ride the clouds. Within your own body, at this very moment, more E. Coli bacteria are thriving than the entire number of human beings who have ever lived!
Bacteria can also have a fearsome bite. Bacterial pneumonia, cholera, diphtheria, leprosy, plague, gonorrhea, tetanus, and typhoid are among the scourges our species knew all too well until the medical revolution of the mid-20th century, when antibiotics made their first miraculous appearance. For the generations that have grown up under their protective shade, it is easy to forget that a doctor’s first line of defense against an infected wound was once a scalpel or amputating saw, not a pill. No longer can a mere nick upon the chin while shaving carry us off by blood poisoning. No longer is it fatal to be in the same room when a stranger coughs.
There is no doubt that the advent of antibiotics was an extraordinary medical advance. Indeed, so pervasive and profound was the impact of antibiotics during their heyday that in 1969 the Surgeon General of the U.S. trumpeted that, “It was time to close the book on infectious disease.”
He could not have been more wrong. Continue reading “Ceasefire: Ending Our War upon Bacteria”
