Relative quantity of cbpA, cps2A, ply, and psaA mRNA in S. pneumoniae strains D39 and ΔD39 with and without CSP. Real-time qRT-PCR was performed to assess the relative mRNA concentrations of cbpA (A), cps2A (B), ply (C), and psaA (D) in S. pneumoniae strains D39 and ΔD39 in the absence or presence of CSP. The levels of individual mRNA species were normalized using as reference the internal control (16S rRNA). ** p < 0.01, NS = no significance.
