FIG. 2.

Effect of H. ducreyi on proliferation and DNA loss of Jurkat T cells. (A) Jurkat T cells were incubated with varying concentrations of FTWC for 24 h and then pulsed with [³H]thymidine. Percent inhibition of proliferation was determined as described in the text. (B) Jurkat T cells were [³H]thymidine labeled, washed, and cultured with FTWC for 18 h. Percent specific DNA loss was calculated as described in the text. FTWC were not treated (open squares) or heat treated for 40 min at 60°C (filled squares). Results are expressed as the means ± standard errors of triplicate wells and are representative of three independent experiments.
