Figure 1

Antibacterial activities of the three vitamin D3 species against H. pylori.

(a) The chemical structures of vitamin D3 (D3), 25-hydroxyvitamin D3 (25D3) and 1α,25-dihydoxyvitamin D3 (1,25D3). (b) FC-free H. pylori strain NCTC 11638 was incubated for 24 h in the presence of each D3 species in a broth and the CFUs were counted. The gray bars in the graphs represent the baseline CFU count measured immediately after the incubation was started. Three independent experiments with the respective D3 species were performed to calculate the mean CFU ± SD per ml.
