Fungal parasite networks in ants

expanded view 1

Microbial parasites may behave collectively to manipulate their host’s behavior. The study examines adaptations of a microbial parasite in its natural environment: the body of its coevolved and manipulated host. Electron microscopy and 3D reconstructions of host and parasite tissues reveal that this fungus invades muscle fibers throughout the ant’s body but leaves the brain intact, and that the fungal cells connect to form extensive networks. Raw images (1,000 images) through 50 μm of head tissue followed by a 3D reconstruction of one muscle fiber (red) surrounded by 25 connected O. unilateralis s.l. hyphal bodies (yellow) (see Fig. 3A for the size of the structures). Images from Ant #1. 3D reconstruction and video created using Avizo software.
