Method description

The Galleria mellonella assay makes use of larvae of the Greater Wax Moth. G. mellonella larvae are injected with a small amount of microorganisms, and survival can easily be followed for up to 1 week. This allows to compare virulence between different organisms. Alternatively, after injection of the microorganisms a treatment can be administered, to determine antimicrobial activity.
