Antibiotic Resistance: Delaying the Inevitable (1 of 2)
Only a few decades ago, antibiotics were considered to be wonder drugs because they worked so well to cure deadly diseases. Ironically, though, many antibiotics have become less effective, precisely because they have worked so well and have been used so often.
Making inroads against infectious disease
Doctors miss the good old days, when the antibiotics they prescribed consistently cured their patients. However, evolutionary theory suggests some specific tactics to help slow the rate at which bacteria become resistant to our drugs.
