Antibiotic-resistant bacteria may be tougher superbugs than previously thought: Not only are these bacteria harder to treat, they appear to be "fitter" in general, meaning they survive better in the host and cause more deadly infections, a new study suggests.
The findings go against the prevailing view in medicine that when bacteria acquire resistance to drugs, they become less "fit" in some way, for example, they spread less easily. Although scientists have assumed this is true, evidence supporting this view is limited, the researchers said.
In the new study, the researchers examined the effect of genes on antibiotic resistance in Pseudomonas aeruginosa, bacteria that cause lung infections. Read more...
