Overview
Gardnerella is a genus of gram-variable bacteria of which Gardnerella vaginalis is the only species. Gardnerella vaginalis can cause bacterial vaginosis in some women.
Diagnosis
Laboratory Findings
Culture
Once classified as a species of Haemophilus, G. vaginalis grows as small, circular, convex, gray colonies on chocolate agar; it will also grow on HBT agar. A selective medium for G. vaginalis is colistin-oxolinic acid blood agar.
While typically isolated in genital cultures, it may also be detected from other sources, such as blood, urine and pharynx. Although a chief cause of bacterial vaginosis, it may be isolated from women without any signs or symptoms of infection.
Microscopy
Under the microscope it appears as a gram-negative rod, although it has been reported to have a gram-positive cell wall. It is associated microscopically with clue cells, which are epithelial cells covered in bacteria.

Reactions
Infections with G. vaginalis go along with proteolysis, giving nitrous products such as cadaverines and putrescines, which can cause a bad smell and loss of water.
Treatment
Medical Therapy
One method of treatment is metronidazole.
