Table 1 Plasmodium falciparum parasitaemia in culture in the presence of plasma from healthy donors and 'immune' plasma

From: Modulating effects of plasma containing anti-malarial antibodies on in vitro anti-malarial drug susceptibility in Plasmodium falciparum

Plasma concentration Median (range) % parasitaemia after 48 hours incubation *
Normal plasma 'Immune' plasma **
Control (MCM) 1.7 (1.5-2.6) 1.7 (1.4-2.3)
2.5% 1.6 (1.5-1.7) 1.7 (1.2-2.1)
5% 1.5 (1.4-1.6) 1.4 (0.7-1.4)
10% 1.5 (1.4-1.7) 1.1 (0.9-1.2) ***
20% 1.4 (1.3-1.4) *** 1.1 (0.5-1.2) ***
40% 1.2 (1-1.4) *** 0.9 (0.7-1.2) ***
  1. *- The percentage of infected red blood cells counted per 1,000 red blood cells.
  2. **- 'Immune' plasma (titre of 1:50)
  3. ***- Significant difference compared to control; p ≤ 0.05 (N = 4). MCM is malaria culture medium.
