We use Bacillus subtilis as a model system to characterize the bacterial stress responses elicited by metal ion limitation and excess during infection, and by host-produced antibiotics that interfere with integrity of the cell envelope. The resulting insights are relevant for understanding the mechanisms that allow bacterial cells (both beneficial and harmful) to adapt to the host environment.
