.. infectious-disease specialists like Brad Spellberg of UCLA's David Geffen School of Medicine have been reading up on those days because of a growing fear they are not all in the past. Wealthy countries take for granted the triumph of science over bacteria, but increasingly doctors are coming up against infections that can be quelled only by the most powerful antibiotics known to medicine—or by none of them. "It's already happening," says Spellberg, to the tune of roughly 100,000 deaths a year from antibiotic-resistant infections in the United States alone. "But it's going to become much more common." Imagine a world in which antibiotics resemble chemotherapy drugs—producing toxic side effects and unpredictable outcomes instead of the guaranteed cures we have come to expect...

We've squandered our antibiotics through overuse—in animal feed, or on diseases they can't cure, such as influenza—and, paradoxically, by under-use.
