The authors demonstrate the presence of putative junctional pores by electron microscopy and other ultrastructural data that would appear to support polysaccharide secretion as the driving force for motility in this organism.
Overall, this study presents observations related to slime-mediated motility on multiple scales (molecular, single-filament and colony), and integrates these findings into a coherent model for the relationship between the cellular organization and the behavior of the colony.
