Figure 3. DFMO affects H. pylori 60190, but has no effect on two other Gram-negative bacteria.

(A) Growth rates of H. pylori 60190 cultured in the absence or presence of 1% DFMO were compared as described in Figure 1B. Dashed lines indicate exponential curve regressions for each data set and are labeled with generation time and goodness of fit (n = 3; *, p<0.05). (B) E. coli DH5α were grown in control broth or broth supplemented with 1% or 2% DFMO and growth was monitored for 8 h. (C) C. rodentium were grown in control broth or broth supplemented with 1% or 2% DFMO and growth was monitored for 8 h.
