    • 2 for 2 days before the test. Strain EGD (13) was prepared for invasion tests as described (2), and a multiplicity of infection (MOI) of about 100 bacteria per cell was used. Vero or Caco-2 cells were treated with wortmannin (Sigma or Biomol) or LY294002 (Biomol) 20 min before infection, as well as during the 60-min infection. Inhibitors were added from 1000X solutions in DMSO, and therefore DMSO was added at a final concentration of 0.1% in the control (0 concentration). At the concentrations used, the inhibitors had no effect on cell or bacterial viability as assayed by the [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT)] test (79) or titering of viable bacteria, respectively. The inhibitors also did not affect bacterial adhesion to Vero or Caco-2 cells.

    • 3 were observed when a smaller MOI was used (100:1), except that these increases were slightly smaller and apparent 15 to 30 min after infection.
