Analysis of the ΔΨm in primary osteoblasts infected with E. faecalis OG1RF using JC-1 staining. a Primary osteoblasts were incubated with E. faecalis OG1RF at MOIs of 10, 100, 500, and 1,000 for 6 and 12 h. The apoptotic cells were evaluated using flow cytometry after JC-1 staining. b The relative intensity of red/green fluorescence was determined. *P < 0.05 and **P < 0.01 versus the control group
