The extent of amplification (ΔCT) for human (rnp) and N. meningitidis (sdhA, NEIS2381, NEIS0417, NEIS2065, NEIS1699, and sodC) markers (A) and the relative extent of selective amplification (ΔΔCT) for N. meningitidis markers (B). Amplification conditions (temperature and protocol) are given at the bottom of the figure, where, e.g., 30_1 indicates SWGA at 30°C using protocol 1. WGA, nonselective whole-genome amplification.
