Session 1: Microbe-Microbe Interactions - Cell Contact-Dependent Outer Membrane Exchange in Myxobacteria
Presented by Dan Wall
Myxobacteria are super cool, a fascinating example of complex cooperative behavior in relatively simple single-celled organisms. They swarm around eating other bacteria until they get low on food, at which point they gather together to form reproductive structures called fruiting bodies to spread to new environments.
As part of the mechanism they use to coordinate their activity and distinguish between friends and foes, they seem to exchange components of their outer membrane, but only with closely-related strains.
