Giant lime green stick insect
Katarzyna Ignasiak and Tony Maxwell (John Innes Centre)

Scientists at the John Innes Centre on the Norwich Research Park are investigating plants as a source of novel antibacterial agents. By selecting plant-insect interactions (shown here, Diapherodes gigantea feeding on eucalyptus leaves [Eucalyptus dalrympleana]), we can isolate bacteria from the insect gut. When we find evidence for resistance to known antibiotics in the gut bacteria, we hypothesise that there are naturally occurring antibacterial compounds present in the plant. We can then use a variety of chemical methods to isolate and identify these compounds, which may represent sources of new antibiotics
