Swarming, Traffic Jams and Biofilms

Transient traffic jam within a monolayer bacterial swarm. Notice the cells being pushed out of the monolayer!

Absolutely delighted that Iago’s paper on the transition from bacterial swarming to biofilms is now out on eLife.

When the expansion of a B. subtilis swarm is hindered (even just by a simple barrier!) cells at the front pile up through a physical process similar to a traffic jam (a transient one in the movie!). This in turn leads to the emergence of a localised biofilm. This is the first direct report we could find of a transition between swarming and biofilm! Great work by Iago and fab collaboration with Munehiro Asally!

Ah! …here’s eLife‘s press release!
