They utilize carbohydrates fermentatively and produce lactic acid as a major end-product [1]. Their Gr… When Gram stain showed mixed flora consisting of gram-positive, gram-negative, or gram-variable bacteria and the Lactobacillus morphotype was decreased or absent (0 to 2+), the Gram stain was interpreted as consistent with BV. Lactobacillus spp. the following information is not yet verified. Please enable it to take advantage of the complete set of features! Duplicate slides prepared from 20 additional specimens of vaginal fluid were stained by two methods and examined by three evaluators. Lactobacillales is one of the diverse and phylogenetically heterogeneous orders of lactic acid producing bacteria that include the type genus Lactobacillus, as well as the genera Facklamia, Granulicatella, Leuconostoc, Pediococcus, and Streptococcus. -, J Clin Pathol.

Interevaluator interpretations and intraevaluator interpretations of duplicate slides were in agreement with one another and with the clinical diagnosis greater than or equal to 90% of the time.

Am J Obstet Gynecol. Lactococcus lactis is a Gram-positive bacterium used extensively in the production of buttermilk and cheese, but has also become famous as the first genetically modified organism to be used alive for the treatment of human disease. Gram stain was consistent with BV in 25 of 25 women given a clinical diagnosis of BV and in none of 35 women with candidal vaginitis or normal examinations. eCollection 2019.

L. lactis cells are cocci that group in pairs and short chains, and, depending on growth conditions, appear ovoid with a typical length of 0.5 - 1.5 µm. 1982 May;35(5):550-4 An inverse relationship between the quantity of the Lactobacillus morphotype (large gram-positive rods) and of the Gardnerella morphotype (small gram-variable rods) was noted on Gram stain (P less than 0.001). -, Am J Med.

When Gram stain showed mixed flora consisting of gram-positive, gram-negative, or gram-variable bacteria and the Lactobacillus morphotype was decreased or absent (0 to 2+), the Gram stain was interpreted as consistent with BV. 2019 May 7;33:9. doi: 10.11604/pamj.2019.33.9.17926. More than meets the eye: associations of vaginal bacteria with gram stain morphotypes using molecular phylogenetic analysis. We concluded that a microscopically detectable change in vaginal microflora from the Lactobacillus morphotype, with or without the Gardnerella morphotype (normal), to a mixed flora with few or no Lactobacillus morphotypes (BV) can be used in the diagnosis of BV. 1981 Jan 15;139(2):130-3 An update and opinion.

To determine whether bacterial vaginosis (BV), also known as nonspecific vaginitis, could be diagnosed by evaluating a Gram stain of vaginal fluid, we examined samples from 60 women of whom 25 had clinical evidence of BV and 35 had candidal vaginitis or normal examinations.
