Figure 2. L. crispatus transiently increases cell division frequency.
Lactobacilli were allowed to colonize a non-confluent layer of ME-
180 cells at 37uC in a 5% CO2 environment for 16 hours. DIC images
were captured at multiple positions every 10 minutes. The number of
cell division events that occurred every 10 minutes during the 16 hours
of the assay is shown for both ME-180 cells alone, and ME-180 cells that
have been colonized with each of the three Lactobacillus strains. The
gray box highlights the increased cell division frequency that was
observed. The red line indicates the average cell division frequency.
