Background

  • Gram-negative or Gram-variable bacillus
  • Member of vaginal flora

Clinical Manifestations

  • Involved in bacterial vaginosis, a dysbiosis rather than infection
  • Rare cause of other infections, including urinary tract infection

Management

  • Bacterial vaginosis (a dysbiosis rather than infection) is usually treated with metronidazole, which helps to normalize the overall vaginal microbiome rather than treating the Gardnerella
  • Very little information about antibiotic susceptibility that would be relevant for treating infections
    • Based on one Brazilian study, ampicillin/sulbactam, clindamycin, chloramphenicol are likely reliable; ampicillin and metronidazole are not[1]
    • A case series reports treatment with ceftriaxone, cefuroxime, aminoglycosides, metronidazole, ciprofloxacin[2]
