Figure 1. Typical growth curves of P. gingivalis W83 in CSE-conditioned and unconditioned medium.

Figure 1

Growth of P. gingivalis was compared in GAM medium and GAM conditioned with CSE (500 ng ml-1 nicotine equivalents). Closed triangles represent growth in GAM. Open triangles represent growth in GAM-CSE. Error bars represent the mean (s.d.) of 3 experiments. There were no significant differences in the growth characteristics of P. gingivalis cultured in GAM or GAM-CSE (p > 0.05).
