Identifying how genomic islands move and their effect on bacterial physiology could lead to new approaches to
bypass bacterial defenses, Hudson said.
A small piece (lower left) of a larger drug molecule (top left) is enough to
distract bacterial defenses and allow the larger molecule to remain inside the bacterium.
Rapidly changing viromes would have signaled an «arms race» in which threatened bacteria were adapting to survive phage attacks, and the phages were adapting to
avoid bacterial defenses.
