| Lateral flagella |
 |
Inducible lateral peritrichous flagellar system is responsible for movement across solid surfaces or through viscous environments known as swarming motility. Glycosylation of the lateral flagellin is essential for swarming motility over surfaces. ... |

|
Types of bacterial movement: swimming, swarming, gliding, twitching and sliding. Only swimming and swarming are correlated with the presence of flagella. Swimming is an individual endeavour, while swarming is the movement of a group of bacteria. Constitutively expressed for motility in liquid environments. ... |

B. bacilliformis is highly motile due to the expression of multiple unipolar flagella. It has been suggested that nonmotile variants bind poorly and do not invade erythrocytes. But B. henselae, B. quintana, and B. tribocorum are nonflagellated but capable of invading erythrocytes, flagella cannot be essential for the process of erythrocyte invasion in these species. ... |

Embedded in periplasmic space between their inner and outer membranes, thus called periplasmic flagella. B. burgdorferi possesses 7 to 11 periplasmic flagella that are inserted at each cell pole and wrap around the cell cylinder to produce the spirochete's distinctive flat-wave
morphology. ... |

Two different (approximately 59-kDa) flagellin subunits, FlaA and FlaB are subject to both antigenic variation and phase variation. The expression of FlaA and FlaB is controlled by different transcription factors, namely the alternative sigma28 (FlaA) and sigma54 (FlaB) transcription factors. Post-translationally modified through O-linked glycosylation. The major modification are pseudaminic acid (Pse5Ac7Ac), a nine carbon sugar that is similar to sialic acid, and an acetamidino-substituted pseudaminic acid (PseAm). There are also minor amounts of a dihydroxyproprionyl form (Pse5Pr7Pr) and an O-acetylated form (Pse5Ac7Ac8OAc). The exact role of glycosylation is unknown. The modification appears to be important for flagellar assembly and may be required for recognition by the flagellar secretion/assembly apparatus. ... |

H. pylori typically produce 4-6 unipolar flagella, which are encased in a membranous sheath and capped by terminal bulbs. ... |

| Flagellar glycosylation/Pse biosynthetic pathway |
|
Flagellar glycosylation is common among a number of bacterial pathogens such as H. pylori and Campylobacter jejuni. H. pylori flagellins are O-glycosylated on serines and threonines with an unusual nine-carbon sugar pseudaminic acid (Pse). ... |

Flagella expression is associated with the cellular cycle in L. pneumophila, the bacteria are not motile while multiplying in host cells, but become motile in the later stages of the infection process. ... |
