(A and B) Normalized fluorescence signals of the beads coated with serotype 14 PS (A) or serotype 9V PS (B) obtained with the panel of test samples (x axis) by use of the multiplexed inhibition type immunoassay with MAbs. The numbers on the X axes represent the numbers assigned to the isolates in the test panel that includes all pneumococcal serotypes and NT isolates. (C and D) Signal-to-noise ratios of the beads coated with probes for serotype 21 (C) and serotype 33F (D) obtained with the panel of test samples by use of the PCR-based multiplexed assay. The panel includes all 93 pneumococcal serotypes that have been identified so far and 4 isolates of NT pneumococci representing both group I and group II. Dashed lines indicate cutoffs and separate the positively reacting serotypes from the nonreacting serotypes.
