Elio Schaechter of Small Things Considered has authored an interesting post today about the motility of bacteria, specifically Paenibacillus, although he does highlight several other strains that swarm, glide or twitch.
"Microbes get around. They can be carried by the wind, by insects, or by water currents, sometimes across large distances, sometimes from one grain of soil to the next. Some bacteria contribute to their own dispersal by their motility or, rarely, one may think, by the motility of other microbes. It’s hard to generalize here because there are just too many variables, too many conditions where microbes are on the move. But this business can be pure fun. So it’s with pleasure that I read about a delightful account of how bacteria can transport fungal spores to the benefit of both."
