Gardnerella vaginalis

STRUCTURE AND PHYSIOLOGY

Gardnerella vaginalis is a non-spore-forming, coccobacillary (intermediate shape between cocci and bacilli), non-motile bacterium. This microorganism possesses a very thin Gram-positive wall that can appear as either Gram-positive or Gram-negative when stained. G. vaginalis is a facultative anaerobe and is often found to proliferate with other anaerobic bacteria in the female genital tract.

TRANSMISSION AND DISEASE

Overgrowth of G. vaginalis and other bacteria in the female genital tract can disrupt the normal microbiome and lead to bacterial vaginosis.

DISINFECTION

Antibiotics are effective for treating bacterial vaginosis either topically or orally.
