Microflora Grade

  • Grade I - when only Lactobacillus cell types (large Gram positive rods) were present.
  • Grade II - (intermediate) when both Lactobacillus and Gardnerella or Bacteroides-Prevotella cell types were present.
  • Grade III - (bacterial vaginosis) when Lactobacillus cell types were absent and only Gardnerella, Bacteroides-Prevotella or Mobiluncus cell types were present.
  • Grade IV - when Gram positive cocci were predominantly present.
