We surveyed Plasmodium spp. diversity in wild chimpanzees living in an undisturbed tropical rainforest habitat and found 5 species: P. malariae, P. vivax, P. ovale, P. reichenowi, and P. gaboni.
Recent studies using molecular approaches demonstrated that wild and captive gorillas and captive bonobos and chimpanzees are infected with P. falciparum and that these apes harbor parasites broadly related to P. falciparum.
We designed a micro-bead device mimicking the geometry of the human narrow and short inter-endothelial slits. Upon filtration through a mixture of 5-25 μm diameter micro-beads, Plasmodium falciparum-hosting RBC (Pf-RBC) were retained in a parasite developmental stage-dependent way, the retention rates of a subset of ring-RBC being similar in micro-beads and in isolated-perfused human spleens.
To examine the contamination by leukocytes of purified erythrocytes from human blood, 20 µl of whole blood was mixed with 10 ml of RPMI 1640, and the mixture was passed through a leukocyte isolation filter.
Importantly, these results also demonstrated that the experimental cerebral malaria model shares many features with human pathology and might be a relevant model to study its pathogenesis.
In this study we examined the downstream effects of reduced haemoglobin digestion on osmoprotection and nutrition. We found that inhibitors of haemoglobinases (plasmepsins, falcipains and aminopeptidases) did not cause premature haemolysis.
