Group B Strep – Streptococcus agalactiae – in the vagina is only starting to get more recognition, though there is still controversy over the impact of group B strep in the vagina. Some believe it is a benign coloniser only, while there is evidence that at minimum, other infections or inflammation of the vagina can result in higher levels of group B strep overall.

This doesn’t mean group B strep is the issue, per se, but it doesn’t mean it isn’t either. It seems important to know at the least if you have high levels of group B strep in your vagina and that correlates to symptoms.

The main reported symptoms being itching and burning, with discharge. It is almost always diagnosed as bacterial vaginosis, yeast infections, or trichomoniasis (a sexually transmitted infection). This leaves many women without relief, untested (because many physicians don’t believe or understand that group B strep affects the vagina). It is often dismissed as a transient bug despite evidence to the contrary.

Symptoms of group B strep overgrowth/infection

  • Itching
  • Burning
  • Discharge – clear or white
  • Red hot labia
  • Possible fissuring of labia
  • Inflammation

Streptococcus agalactiae is the gram-positive bacterium responsible for the vaginal and vulvar inflammation and discharge, but it also causes lactobacilli to become more rare in the vagina and cause the pH to become more alkaline (which isn’t good).

There are multiple strains being discovered, and that is one reason why it is hard to identify. In addition, not all testing gear is created equal and can’t necessarily easily pick up these sorts of bacteria.

About Group B Strep (GBS)

This infection typically affects newborn babies and can result in life-threatening infections that cause septicaemia, meningitis and pneumonia. It can affect adults, and typically causes diseases on the skin, in soft tissues, the urinary tract, and involving the bones and joints.

This bacteria is known to provoke an inflammatory reaction in the vagina, decrease lactobacilli populations, and causes very red, hot labia, perhaps even with vaginal fissures.

Treatment of group B strep

The medical treatment of group B Strep vaginitis may be a combination of topical lactobacilli probiotics plus antibiotics. Partners should be treated also.

Identification failure and misdiagnosis of group B strep

Some GBS isolates are thought to be less common, which may contribute to misdiagnosis. Variants can behave differently, producing a variety of symptoms.
