TLDR
It is postulated that flagellar sheaths may allow for specific interaction between a bacterium and a surface, and there is a problem as to the relationship between a rapidly rotating flageLLum and the sheath.Abstract:
Although bacterial flagellar sheaths were observed over 30 years ago, they may still be characterized as structures in search of a function. In addition to true sheaths, bacterial flagella may possess other adornments that cause an increase in the organelle's cross-sectional diameter. These "complex flagella" are sharply differentiated from sheathed flagella. Immunological and chemical distinctions have been found between flagellar sheaths, flagellar cores, and LPS layers inferred to be the sheath sensu stricto. Although complex flagella may serve as specific receptors for flagellotropic phages or in allowing for more efficient swimming in viscous environments, similar functions have not yet been attributed to true sheaths. It is postulated that flagellar sheaths may allow for specific interaction between a bacterium and a surface. In addition, there is a problem as to the relationship between a rapidly rotating flagellum and the sheath.read more

TL;DR: The regulation of motility during biofilm formation in Bacillus, Pseudomonas, Vibrio, and Escherichia is reviewed, and it is concluded that the motility-to-biofilm transition, if necessary, likely involves two steps.

Dual flagellar systems enable motility under different circumstances.
TL;DR: This review focuses on the polar and lateral flagellar systems of Vibrio parahaemolyticus, which have been identified encoding distinct structural, motor, export/assembly, and regulatory elements.

Bdellovibrio bacteriovorus gen. et sp. n., a predatory, ectoparasitic, and bacteriolytic microorganism.
H. Stolp,M. P. Starr +1 more
TL;DR: All presently known isolates ofBdellovibrio possess lytic activity only against gram-negative bacteria; the individual strains, however, show certain differences in their host activity spectra; some have a restricted host range, while others are able to attack a broad spectrum of host bacteria.

TL;DR: The results suggest that L-fucose-containing structures of eukaryotic cell surfaces may function as receptors for the vibrio adhesin and may therefore be an important determinant of host susceptibility.
