Expression of pgfur gene in P. gingivalis strains. Relative expression of the pgfur gene was determined using RT-qPCR and shown in relation to iron/heme availability (a) and additionally to growth phase (b) at the indicated time points. Data are shown as relative levels of the mRNA normalized to 16S rRNA mRNA and presented as mean ± standard deviation (mean ± SD) from three replicates. **P < 0.01, ***P < 0.001
