    ATCC atcc 14019 strain
    Vaginal epithelial cell morphology (a–d) and changes in 16S rRNA gene copy number of G. vaginalis and lactobacilli in the vaginas of GV-infected mice following LasA or antibiotic treatment (e,f). Vaginal secretion smears from GV JNFY14-infected mice showing epithelial cells and adherent GV cells. Insets highlight zoomed-in regions (scale bar, 10 μm; inset bar, 2 μm). (a) Uninfected epithelial cells; (b) GV-infected vaginal epithelial cells without treatment; (c) GV-infected vaginal epithelial cells after LasA treatment; (d) GV-infected vaginal epithelial cells after ERM treatment. Arrows indicate GV cells adhered to epithelial cell surface. Biomass changes of G. vaginalis and lactobacilli populations after treatment in the vagina of mice infected with GV JNFY14 (e) or GV <t>ATCC</t> <t>14019</t> (f). Successfully infected mice were divided into 3 groups and treated once a day for 6 days: Group 1 was treated with 20 μg/mL LasA, group 2 was treated with the same concentration of antibiotics (ERM for strain JNFY14 and MTZ for strain ATCC 14019, respectively); and the control group was treated with an equal volume of 50 mM PBS buffer (pH 7.0). Statistical analysis was carried out using GraphPad Prism 9.5.1. ∗∗, p < 0.05; ∗∗∗, p < 0.01; ∗∗∗∗, p < 0.005.
