Superbugs may be here to stay - New Scientist: "Multidrug-resistant bacteria may be here to stay. The common wisdom that superbugs with antibiotic resistance are outcompeted by their non-super neighbours in the absence of antibiotics has been turned on its head.
Bacterial antibiotic resistance is a major concern because it can lead to the appearance of dangerous and difficult-to-treat infections in humans. Resistance generally occurs in one of two ways: either through mutations in the bacterial DNA or, more commonly, through the acquisition of resistant genes from other organisms through horizontal gene transfer."
