New Method Weakens, Doesn't Destroy Bacteria

Researchers at University of Wisconsin have developed a method of dealing with bacteria in the human body that does not kill the bacteria, as antibiotics do. Rather, the new mechanism removes the bacteria's ability to harm cells within the body.

The new method involves displacing plasmids--which carry the genes responsible for bacteria's virulence and antibiotic resistance--with strands of DNA from other, less dangerous, bacteria.

By leaving the bacteria alive, this method prevents other, possibly more dangerous, bacteria from swarming into the vacancy. It also prevents benign bacteria from being killed by harsh antibiotics.

Does bacteria weaken as it passes from person to person?
