Fig. 2

Reactivity of serially diluted culture parasites on RDTs showing relative band intensities. Band intensities are graded as 0 (negative) or 1–4 (positive with increasing band intensity respectively). Dd2 (hrp2− /hrp3+), was reactive on all HRP2 bands at 100 parasites/µL (a, b, c) and in one case at 10 parasites/µL (c). Only for the double deleted 3BD5 (hrp2− /hrp3−) was HRP2 reactivity completely lost irrespective of parasite density (a, b, c). All parasites were reactive on the pan-LDH band
