(A) Percentage of A. stephensi mosquitoes infected with WT (gray, n = 4) and sufA
– (brown, n = 6) parasites. Shown is the mean percentage (± S.D.) from independent mosquito feeding experiments. For sufA
– infections, both isogenic strains, sufA
–1 (n = 4) and sufA
–2 (n = 2), were transmitted to mosquitoes and data combined. (B) Mean sporozoite number (± S.D.) in salivary glands (days 17–21 after infection) from the same independent mosquito feedings as shown in panel A (WT, n = 4; pooled sufA
–, n = 6). (C) Liver stages development of WT and sufA
– parasites in cultured hepatoma cells. Shown are mean numbers (± S.D.) of intracellular parasites at the time points indicated from two experiments done in quadruplicate each. (D) Merosome formation at 72 h after infection. Shown are mean values (± S.D.). None of the sufA
– data points were significantly different from the corresponding WT values (P>0.05; non-parametric, two-tailed Mann-Whitney’s test).
