    Area of Science:

    • Microbiology
    • Bacteriology
    • Cell Biology

    Background:

    • Campylobacter jejuni and Campylobacter fetus are significant bacterial pathogens.
    • Bacterial flagella are crucial for motility and virulence.
    • The detailed ultrastructure of the flagellar apparatus in these species is not fully elucidated.

    Purpose of the Study:

    • To describe a previously unrecognized bacterial flagellar structure.
    • To investigate the location and morphology of this novel structure.
    • To discuss its potential functional and taxonomic implications.

    Main Methods:

    • Utilized advanced electron microscopy techniques.
    • Performed detailed ultrastructural analysis of Campylobacter jejuni and Campylobacter fetus.
    • Comparative morphological analysis of flagellar components.

    Main Results:

    • Identified a disc-shaped structure located beneath the flagellar insertion point.
    • The structure measures approximately 100 nm in diameter.
    • Observed eleven spokes radiating from a central hole within the structure.

    Conclusions:

    • A novel component of the bacterial flagellar apparatus has been identified.
    • This structure's presence in Campylobacter species suggests a conserved role.
    • Further research is needed to determine its precise function and taxonomic significance in spiral bacteria.
