Bacterial vaginosis (BV) is an infection of the vagina caused by excessive growth of bacteria. [ 6 ] [ 12 ] Common symptoms include increased vaginal discharge that often smells like fish. [ 2 ] The discharge is usually white or gray in color. [ 2 ]
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 ...
Infections (bacterial vaginosis, vaginal yeast infection, trichomoniasis), allergic reactions, low estrogen [2] Diagnostic method: Based on examination, measuring the pH, culturing the discharge [3] Differential diagnosis: Inflammation of the cervix, pelvic inflammatory disease, cancer, foreign bodies [3] Treatment: Based on the cause [1] Frequency
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.
Bacterial vaginosis — an overgrowth of bacteria that can cause discharge and a "fishy" odor — is the most common vaginal infection in women, affecting nearly 30% between 15 and 44 years old ...
Gram stain of cells from the vagina (the same magnification) with normal bacterial flora (top) and the bacteria that cause vaginosis (bottom). A variety of diagnosis techniques are currently available for identifying Gardnerella vaginalis such as the OSOM BV Blue assay, FemExam cards and nucleic acid amplification tests (NAATs), resulting in the determination of ongoing BV.
Normal vaginal flora (left) is predominantly rod-shaped Lactobacilli, whereas in bacterial vaginosis (right) there is an overgrowth of bacteria, which can be of various species. A healthy vaginal microbiome aids in the prevention of bacterial vaginosis, yeast infections and other possible problems by maintaining an acidic pH (< 4.5) that is ...
It is the aerobic counterpart of bacterial vaginosis. The lack of acknowledgement of the difference between the two conditions might have led to inaccurate conclusions in several studies in the past. [4] The entity that has been described as "desquamative inflammatory vaginitis" probably corresponds to the more severe forms of aerobic vaginitis ...
