Figure 4

Nitrite and nitrate concentrations in the supernatant of HCT116 cells which were infected with H. cinaedi. Means ± SD are shown for n = 5. The initial cell numbers were 1 × 106 for HCT116 and 1 × 107 or 1 × 108 for H. cinaedi, yielding multiplicity of infections (MOI) of 10 or 100. The times (24 or 48 h) correspond to the duration of exposure to the bacteria. The increased NO2− concentrations for MOI = 100 are evidence of NO synthesis by the HCT116 cells.
