Diagnosis: 

  • cells are spherical
  • diameter of cells 1.8 – 2.2 µm
  • cells with highly refractive granules, mainly in the center
  • cells are colorless
  • colonies consist of loose aggregations of clusters of 2-16 cells
  • a gelatinuous sheat around the colonies, only visible due to adherent bacteria
  • colonies about 20 – 100 µm in diameter
