Effect of human complement on ABS replication and gametocytogenesis.
A. Effect of human complement on ABS replication. Ring stage cultures of strain NF54 with a starting parasitemia of 0.5% were maintained in cell culture medium supplemented with either 10 vol% NHS or HIS at 37°C over a period of 0–120 h to follow three generations (G1–3). The parasitemia was evaluated every 12 h via Giemsa smears. Significant differences in parasitemia are indicated (* p < 0.05, *** p < 0.001; Bonferroni post‐test, two‐way ANOVA). The experiment was performed in triplicate (mean ± SD); the data are representative for one of two independent experiments.
B. Effect of human complement on gametocytogenesis. Ring stage cultures of strain NF54 with a starting parasitemia of 5% were maintained in cell culture medium supplemented with either 10 vol% NHS or HIS at 37°C over a period of 0–240 h. The gametocytemia was evaluated every 24 h via Giemsa smears. Significant differences in gametocyte numbers are indicated (** p < 0.01, *** p < 0.001; Bonferroni post‐test, two‐way ANOVA). The experiment was performed in triplicate (mean ± SD); the data are representative for one of two independent experiments.
