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.
