What is non-specific vaginitis/bacterial vaginosis?

Non-specific vaginitis/bacterial vaginosis is the most common type of vaginal infection, representing 40-50% of all vaginal infections. The others are yeast (candida) and trichomonas infections.

What are the symptoms?

Between 50 and 75% of women who have non-specific vaginitis/bacterial vaginosis have no noticeable symptoms. For others, the most common symptoms are:

  • Abundant, grayish or white discharge
  • An unpleasant odour (“fishy” odour), which may be more noticeable after sexual intercourse and during menstruation
  • A vaginal pH level over 4.5

Whereas other types of vaginal infections cause inflammation and irritation/itching of the vagina, non-specific vaginitis/bacterial vaginosis does not usually cause these symptoms.

How is non-specific vaginitis/bacterial vaginosis diagnosed?

If you suspect that you have a vaginal infection, it is recommended that you consult a healthcare professional to obtain an accurate diagnosis. He or she will be able to determine whether you have non-specific vaginitis/bacterial vaginosis using one of several simple tests:

  • By examining the appearance and colour of vaginal secretions, collected using a cotton swab, under a microscope: normal secretions are generally white or clear, whereas in patients with non-specific vaginitis/bacterial vaginosis, they are often grayish, milky, thin and sometimes abundant
  • By examining a sample of vaginal secretions under a microscope to detect the presence of bacteria (coccobacilli) adhering to the cells, indicating the presence of non-specific vaginitis/bacterial vaginosis
  • By measuring the acidity of vaginal secretions using pH paper: patients with non-specific vaginitis/bacterial vaginosis will have a high pH level (>4.5) compared to the more acidic protective pH levels found in normal vaginal secretions
  • By smelling vaginal secretions to determine whether they have an unpleasant (“fishy”) odour after adding a chemical agent called potassium hydroxide (KOH)

How to distinguish the various types of vaginal infections

Although non-specific vaginitis/bacterial vaginosis is the most common type of vaginal infection, representing between 40 and 50% of all cases, only a healthcare professional can confirm that it is not a yeast infection (candida) or Trichomoniasis (an STI), which require different treatments.

If you suspect that you have a vaginal infection, it is recommended that you consult a healthcare professional to confirm an accurate diagnosis. While you wait for your appointment, here is an overview of the symptoms of the most common types of vaginal infections:

 Non-specific vaginitis/bacterial vaginosisVulvovaginal Candidiasis (yeast infections)Trichomoniasis
Itching / burning sensation Sometimes Usually Always
Discharge/odour Thin, milky, grayish-white, with a fishy odour Thick, odorless, white (cottage cheese-like) Excessive and foul-smelling; may be yellow or green and foamy
Causes Bacteria Yeast (Candida) STI caused by the Trichomonas vaginalis protozoan parasite

Causes of non-specific vaginitis/bacterial vaginosis

When the vaginal environment loses its acidity due to physiological or external factors, protective lactobacilli disappear and harmful bacteria (primarily Gardnerella vaginalis) multiply and become infectious.
