fliL is the first gene in a flagellar operon that specifies members of the switch complex and type III export system in Salmonella enterica and Escherichia coli, but no function has been ascribed to this gene thus far. Here we report that a fliL mutant is slightly impaired for swimming but completely defective in swarming in both organisms, and have studied this phenotype further in S. enterica. We have found that on swarm agar, mutant cells release or 'eject' their flagellar filaments. The… CONTINUE READING
