Figure 2. Effect of hCMV concentration on adherence of Actinobacillus actinomycetemcomitans strains to HeLa cells. Cells were exposed to hCMV for 1 hr (MOI range: 10–200) and incubated for an additional 48 hrs. Uninfected cells served as controls. Data are expressed as the proportion of cell-associated bacteria relative to the numbers of bacteria added to the cells initially. Each datapoint represents the mean ± SEM for 4 independent experiments. *P < 0.05, hCMV-infected group vs. uninfected controls. #P < 0.05, Actinobacillus actinomycetemcomitans strain IDH1705 vs. strains JP2 and ATCC33384 at MOI 200.
