Scoring system (zero to 7+)* is a weighted combination of the following bacterial morphotypes:
	A. Lactobacillus acidophilus (large gram-positive rods) B. Gardnerella vaginalis and Bacteroides species (small gram-variable or gram-negative rods) C. Mobiluncus species (curved gram-variable rods)
The total score is the sum of the weighted quantity of the three bacterial morphotypes.
Scoring for each of the above bacterial morphotypes:
	Zero = No morphotypes per oil-immersion field
	1+ = Less than one morphotype per oil-immersion field 2+ = One to four morphotypes per oil-immersion field 3+ = Five to 30 morphotypes per oil-immersion field 4+ = More than 30 morphotypes per oil-immersion field
