Figure 4. Effect of IE-antigen expression on adherence of Actinobacillus actinomycetemcomitans strain JP2 to confluent monolayers. HEL and primary cells were exposed for 1 hr to hCMV or the mock preparation (MOI 100) and incubated for 96 hrs. Uninfected cells served as controls. Data are expressed as the proportion of cell-associated bacteria relative to the number of cell-associated bacteria on uninfected control cells (= 100%). Each datapoint represents the mean ± SEM for 6 independent experiments. *P < 0.05, hCMV- or mock-infected group vs. uninfected control; #P < 0.05, hCMV vs. mock-infected group.
