Sites of close contact between gliding Cytophaga sp. strain U67 cells and glass were examined by interference reflection microscopy. Site patterns changed during translocation and moved relative to the substratum, in contrast to previous interference reflection microscopy observations of fibroblast and amoeboid motility. Sinistral rotation around the long axis of the cell was coupled with gliding, except when curved cells traversed curvilinear pathways. Close contact was temporary, since cells flipped up off the substratum on one pole, pivoted, or were displaced laterally in collisions. Other members of the order Cytophagales and Myxococcus sp. demonstrated similar patterns of close association with substrata.
