Molecular quantification of Plasmodium falciparum ookinete load in individual Anopheles coluzzii mosquitoes during 12–36 hpi identifies low- and high-ookinete infection intensity groups linked to distinct early immune transcription.
- Why it matters: Early parasite development in mosquitoes is pivotal for establishment and transmission, but measuring ookinete burden during maturation and midgut invasion is difficult, limiting insight into host–parasite dynamics at the individual level.
- What they did: Mosquitoes were fed on P. falciparum-infected blood with identical gametocytemia, then ookinete load was quantified at 12, 18, 24, and 36 hpi using qPCR of four ookinete-associated transcripts (ctrp, warp, soap, cht1). RNAseq compared mosquitoes with low versus high infection intensities to test links to mosquito transcriptional responses.
- The result: The four markers’ transcriptional patterns correlated, and RNAseq showed distinct profiles where lower parasite burdens had stronger, more coordinated immune-related gene expression at 12 and 24 hpi, with L-arginine homeostasis genes significantly modulated.
