Gardnerella encourages invasive GBS disease
Gilbert, NM Foster LR, Cao B, Yin Y, Mysorekar IU, Lewis AL. Gardnerella vaginalis promotes group B Streptococcus vaginal colonization, enabling ascending uteroplacental infection in pregnant mice. Am J Obstet Gynecol, 2020 Nov 25, S0002-9378(20)31331-4. doi:10.1016/j.ajog.2020.11.032 PMID: 33248136
Co-inoculation with Gardnerella results in increased GBS invasive ascending infection. Left: Schematic of the basic experimental design.
(A-B) Number of dams without or with bacterial cfu in uterine horn (A) or placental (B) tissue homogenates. Percentage of dams with detectable cfu indicated across the top of each bar. Fisher’s exact test *P < 0.05; np = not powered.
