FIG 5.

AMB-1 runs are interrupted by short pauses and tumbles. (A) Time-lapse images extracted from Movie S5 in the supplemental material showing an AMB-1 cell pausing in the midst of a run (frames 6 to 20). Exposure time, 100 ms. Bar, 4 μm. The letter B and the vector above it indicate the orientation of the local magnetic field. (B) Tumbles are caused by two flagella showing the same fluorescent pattern. Time-lapse images were extracted from Movie S8. The pictogram under each frame represents an interpretation of the flagellar motion depicted in the image above it. Exposure time, 80 ms. Bar, 2 μm.
