Spread of antibiotic resistance understood by unravelling bacterial secretion system

The system that allows the sharing of genetic material between bacteria -- and therefore the spread of antibiotic resistance -- has been uncovered by a team of scientists. Understanding the structure of the secretion system will help scientists uncover the mechanism by which it moves substances across the inner and outer membranes. It could eventually help scientists develop new tools for the genetic modification of human cells, as the bacteria could act as a carrier for genetic material, which ...
