Bacteria invasion of mucus. (A) Schematics of the experiment: a droplet of mucus in contact with a droplet of bacteria-rich TB is sandwiched between two parallel glass slides. (B) Trajectories of Bacillus subtilis (strain 1085) obtained in the region with TB, by consecutive snapshot accumulation over 8.5 seconds. The bacteria display the well known circles close to a wall. The image is (125 × 94) μm. (C) Trajectories of bacteria over 8.5s at the interface of the droplets. The bacteria penetrate in the direction of the red arrow. Scale bar 100 μm. (D) Velocity and wobbling amplitude of a bacterium penetrating mucus.
