Leaf-cutter ants |
Following close on my article a few days ago on the antibiotic found in the skin of an Australian toadlet and how this demonstrates the need to maintain a rich biodiversity if only for the resource of natural medicines yet to be discovered in nature, we have another example of an unlikely compound being found - within the nest of leaf-cutter ants.
This time, it's an antifungal compound, produced by bacteria that live on the attine ants (ants of the Atta genus of what are more commonly known as leaf-cutter ants that farm fungi on a substrate of moist chewed-up leaf matter). The ants use this antifungal compound, called attinimicin, to keep their crop and its substrate free from fungal parasites.
