Gardnerella vaginalis is a species of Gram-variable-staining facultative anaerobic bacteria. The organisms are small (1.0–1.5 μm in diameter) non-spore-forming, nonmotile coccobacilli . [ 3 ]
They are a medical sign of bacterial vaginosis, particularly that caused by Gardnerella vaginalis, [2] a group of Gram-variable bacteria. This bacterial infection is characterized by thin gray vaginal discharge, and an increase in vaginal pH from around 4.5 to over 5.5.
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 ...
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 ...

Diagnostic microbiology is the study of microbial identification. Since the discovery of the germ theory of disease , scientists have been finding ways to harvest specific organisms. Using methods such as differential media or genome sequencing , physicians and scientists can observe novel functions in organisms for more effective and accurate ...
