Bacteriophage-like particles were identified in Bartonella bacilliformis cultures. These particles possess an icosahedral head measuring 40 nm and a 16 nm tail, suggesting novel viral structures in this bacterium.

Area of Science:

  • Microbiology
  • Virology
  • Bacteriology

Background:

  • Bartonella bacilliformis is a human pathogen responsible for Carrion's disease.
  • The presence and morphology of bacteriophages within Bartonella species are not well-characterized.

Purpose of the Study:

  • To investigate the ultrastructure of particles observed in Bartonella bacilliformis cultures.
  • To identify and describe potential bacteriophage-like entities associated with this bacterium.

Main Methods:

  • Culturing of Bartonella bacilliformis.
  • Electron microscopy for particle visualization and characterization.

Main Results:

  • Bacteriophage-like particles were detected in Bartonella bacilliformis cultures.

  • The observed particles featured an icosahedral head (40 nm in diameter) and a tail (16 nm in length).

    • Conclusions:

    • The findings suggest the presence of novel bacteriophage-like structures in Bartonella bacilliformis.
    • Further research is warranted to elucidate the nature and implications of these particles in the bacterium's biology.
