Formation of multiple treponemes

V Wolf1, J Wecke

  • 1Robert Koch-Institut, Berlin, Germany.

Zentralblatt Fur Bakteriologie : International Journal of Medical Microbiology

Summary

Treponemes form pseudomulticellular structures by losing individual sheaths and flagella to create a common outer envelope. This transformation involves unseparated helical and plait-like forms, potentially impacting pathogenesis.

Area of Science:

  • Microbiology
  • Cell Biology
  • Microscopy

Background:

  • Treponemes are helical bacteria known for various pathogenic species.
  • Understanding bacterial morphology is crucial for identifying novel life cycle stages.

Purpose of the Study:

  • To analyze the formation process of pseudomulticellular treponemes.
  • To investigate the structural changes during the development of these complex forms.

Main Methods:

  • Utilized advanced electron microscopy techniques.
  • Included thin sectioning, freeze fracturing, and scanning electron microscopy.

Main Results:

  • Observed the development of spherical bodies preceded by helical and plait-like structures.
  • Documented the loss of individual outer sheaths and axial flagella.
  • Identified the formation of a common outer envelope enclosing multiple bacteria.

Conclusions:

  • Pseudomulticellular treponeme formation involves significant structural reorganization.
  • These unique structures may have implications for treponemal pathogenesis and survival.
