Escherichia coli can form linear trails and move in a flagellum-independent manner on semisolid agar containing carbon sources. Trail formation seemed to correlate with the growth speed and/or carbon metabolism. Cell morphology in linear trails changed into larger cell sizes. We speculate that the flagellum-independent trail formation is a new mechanism for migration of E. coli cells.
