Normal: Gram stain shows a predominance of Lactobacillus acidophilus (3+ or 4+), with or without Gardnerella vaginalis.
Bacterial vaginosis: Gram stain shows mixed flora (gram-positive, gram-negative or gram-variable bacteria) and absent or decreased
	L. acidophilus (zero to 2+). A. L. acidophilus (large gram-positive bacilli) B. G. vaginalis (small gram-variable rods)
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 five morphotypes per oil-immersion field 3+ = Six to 30 morphotypes per oil-immersion field 4+ = More than 30 morphotypes per oil-immersion field
