Gardnerella vaginalis was described in 1953 by Sidney Leopold as a nonmotile, nonencapsulated, pleomorphic gram-negative rod from the vaginas of women who showed symptoms of cervicitis. As though it's been suggested that the organism was related to the genus Haemophilus due to its morphology and growth conditions, the relation between this ...
Grade 2 (Intermediate): Some lactobacilli present, but Gardnerella or Mobiluncus morphotypes also present. Grade 3 (Bacterial Vaginosis): Predominantly Gardnerella and/or Mobiluncus morphotypes. Few or absent lactobacilli. (Hay et al., 1994) Gardnerella vaginalis is the main culprit in BV. Gardnerella vaginalis is a short, Gram-variable rod ...
Mobiluncus is a genus of Gram-positive, [2] anaerobic, rod-shaped bacteria.These bacteria may be stained either Gram-negative or Gram-variable. However, they are classified as Gram-positive rods due to the fact that they possess a Gram-positive cell wall, lack endotoxin and are sensitive to vancomycin, erythromycin and ampicillin, but resistant to colistin.
Bacterial vaginosis is most often caused by an overgrowth of a common type of bacteria called gardnerella vaginalis. Certain risk factors, such as douching, can disrupt the balance of “good ...
Lactobacilli have been shown to inhibit in vitro growth of pathogenic microorganisms, e.g. Bacteroides fragilis, Escherichia coli, Gardnerella vaginalis, Mobiluncus spp., Neisseria gonorrhoeae, Peptostreptococcus anaerobius, Prevotella bivia and Staphylococcus aureus. It is generally accepted that this is achieved mainly through the action of ...

The Nugent Score is a Gram stain scoring system for vaginal swabs to diagnose bacterial vaginosis (BV).The Nugent score is calculated by assessing for the presence of large Gram-positive rods (Lactobacillus morphotypes; decrease in Lactobacillus scored as 0 to 4), small Gram-variable rods (Gardnerella vaginalis morphotypes; scored as 0 to 4), and curved Gram-variable rods (Mobiluncus spp ...
