Frozen motion of gliding bacteria outlines inherent features of the motility apparatus.

Abstract excerpt

High-resolution data of actively gliding wild-type bacteria of four different species and of four different gliding mutants of Myxococcus xanthus were obtained from scanning electron micrographs. By shock freezing and freeze drying, motility-associated surface patterns could be fixed and consequently distinct intermediate states of motion could be observed for the first time. It is shown that these topographic...
