What is bacterian vaginosis?

The vagina contains bacteria. It is 95% composed by Doderlein’s Bacillus which produce lactic acid and allow vaginal ph to be maintained at around 3.8 – 4.5. Amongst the other types of bacteria found in the vagina, gardnerella vaginalis is also present, it belongs to the anaerobic group of bacteria. Anaerobic bacteria develop when the absence of oxygen is total. Bacterial vaginosis is a vaginal flora imbalance and arises when anaerobic bacteria become a majority. Therefore, bacterial vaginosis is not an infection, it is an imbalance between the species which are normally found in the vagina which results in a rise of harmful bacteria and a decrease of good bacteria. Good bacteria, named lactobacillius normally protect the vagina, by maintaining an optimum level of acidity and preventing the growth of pathogenic organisms.

Signs of bacterian vaginosis

Two of the following clinical signs are sufficient to diagnose bacterial vaginosis:

  • Bad vaginal smell
  • Vaginal discharge
  • Vaginal ph superior to 5
  • Presence of clue cells during examination. This exam consists in observing cells with a microscope in order to determine whether they contain bacteria or not.


Bacterial vaginosis does not always cause discomfort. However generally the discomforts are the following:

  • Itching
  • Burning sensation
  • Whitish or greyish discharge
  • Unpleasant smells (fishy)

Causes of bacterian vaginoseis

Bacterial vaginosis occurs when certain types of bacteria which are normally found in the vagina start to multiply in abundance. The causes of this imbalance are not exactly known, however certain factors may increase the risk of bacterial vaginosis:

  • Intra-uterine devices
  • Vaginal douches
  • Using feminine hygiene products
  • Bubble bath
  • Anal intercourse
  • Tobacco

What is more, even if bacterial vaginosis is not a sexually transmitted disease, it is possible that sexual intercourse without condoms increases the risk of bacterial vaginosis because of the effect of sperm on vaginal bacteria.

Bacterial vsaginosis diagnosis

Diagnosing Bacterial vaginosis is established by examining:

  • Acidity
  • Odor
  • The characteristics
  • Vaginal discharges

Complications linked to bacterial vaginosis:

In female adults

Bacterial vaginosis may cause pelvic inflammatory disease when pathogens climb up to the top of the female genital organ. Bacterial vaginosis also increases the risk of catching a sexually transmitted disease, by decreasing the vaginal flora’s natural defenses.

Bacterial vaginosis may lead to severe complications for pregnant women, such as:

  • Bleeding, especially during the first and second month of pregnancy
  • Two times more risk of abortion
  • Higher risk of premature delivery
  • Amniotic fluid infection which can lead to lung and neurological problems at the child’s birth

What are the existing solutions?

What can be used against bacterial vaginosis?

Bacterial vaginosis can normally be treated with antibiotics. The most commonly prescribed are metrodinazole, clindamycin and secnidazole. Nevertheless, even if treatment is efficient, relapses are recurrent. At 4 weeks, the relapse rate is 30% and 82% after three months.

That is why Sérélys Pharma laboratories have created Sérélys® Vaginal Care which helps to relieve and prevent bacterial vaginosis relapses while protecting against vaginal thrush.

The solution : Sérélys® Vaginal Care

Sérélys® Vaginal Care is a CE 1253 medical device which treats and prevents bacterial thrush whilst protecting against vaginal thrush. Sérélys® Vaginal Care is hormone and preservative free (paraben free).
