Values represent total pooled experimental results with prevalence's expressed as percentages (no. of mosquitoes infected/no. of mosquitoes dissected). Number of times each parasite isolate was fed to mosquito combinations was as follows: 3D7, 3 paired feeds; K39, 2 paired feeds, 1 single feed An. stephensi; M24, 2 paired feeds; P018, 2 paired feeds, P019, 2 paired feeds; P020, 1 paired feed; PNG12.2, 3 single feeds An. stephensi; PNG37.2, 1 paired feed; PNG51.1, 1 paired feed; 1776.3.7, 1 paired feed. * Indicates statistically significant comparison performed by χ² test; probability considered significant at P < 0.01. N/A = not applicable.
