Scientists model outer membrane of 12 bacterial species to speed new drugs for 'bad bugs'
Scientists model membrane 12 bacterial species speed new drugs bad bugs
2016/11/4
As bacteria change their behavior to foil the drugs designed to kill them, illnesses that were once relatively easy to treat become difficult to cure. The phenomenon is known as antibiotic resistance,...
We generally think of inheritance as the genetic transfer from parent to offspring and that evolution moves toward greater complexity. But there are other ways that genes are transferred between organ...
