Bacteria Motility

Borrelia burgdorferi (Bb) (Lyme spirochete) moving back and forth along a platelet

Time-lapse (16x normal) phase-contrast videomicrocopy.

  • In order to clear the body of infecting spirochetes, phagocytic cells must be able to get hold of them.
  • real-time phase-contrast videomicroscopy measured the speed of Borrelia burgdorferi (Bb), the Lyme spirochete, moving back and forth (bidirectional motor capacity) across a platelet to which it was tethered.
  • mean crossing speed was 1,636 µm/min (N = 28), maximum, 2800 µm/min (N = 3).
  • fastest speed recorded for a spirochete
  • two orders of magnitude above the speed of a human neutrophil, the fastest cell in the body.
