Figure 2. Correlation of antigen-specific memory B cells and serum IgG titers in LVR versus NOP children.

Figure 2

(A) Frequencies of antigen-specific memory B cells (MBCs). (B) Serum immunoglobulin G (IgG) titers to 5 pneumococcal protein antigens. (C) Correlation between PhtD-specific serum antibody titers and PhtD-specific percentages of antigen-specific MBCs. Data are for 10 LVRsOP children and 12 non–otitis prone (NOP) children. Open circles denote otitis prone and closed circles denote non–otitis prone. *P = 0.05; ** P = 0.005.
