Curved, gram-variable anaerobic rods seen in the vaginal discharge of bacterial vaginosis belong to the genus

  • A.Mobiluncus
  • B.Veillonella
  • C.Bifidobacterium
  • D.Eubacterium

Answer: B

Correct answer: Mobiluncus

Mobiluncus species are curved, motile, gram-variable anaerobic rods found in bacterial vaginosis along with Gardnerella vaginalis and various anaerobes, replacing the normal lactobacillary flora. Their comma or gull-wing shape on a wet mount or Gram film is a useful pointer. Veillonella is a Gram-negative coccus, and Bifidobacterium and Eubacterium are Gram-positive rods of the gut and are not implicated in this syndrome.
