Hematology: Assessing the safety and efficacy of a test-based, targeted donor screening strategy to minimize transfusion transmitted malaria

In 2005, the Australian Red Cross Blood Service implemented a malaria antibody testing based strategy for donors with a history of travel/residence in a malaria endemic country or a past history of malaria. This report assesses the safety and efficacy of the strategy since inception.

These results suggest that despite the potential for inter-form gene flow through hybridization, actual (realized) gene flow between M and S may be substantially less than commonly assumed and may not explain most shared variation.

The present paper deals with the isolation and identification of antiplasmodial compounds from C. divaricatum in Carpesium spp. This is the first report on the antiplasmodial activity of the compounds from C. divaricatum.

The methanolic extract of the rhizomes parts of Agelica purpuraefolia was investigated for its activity against chloroquine-sensitive strains of Plasmodium falciparum using the parasite lactate dehydrogenase assay method.

Plasmepsins II (EC number: 3.4.23.39) and IV (EC number: 3.4.23.B14) are aspartic proteases present in the food vacuole of the malaria parasite Plasmodium falciparum and are involved in host hemoglobin degradation.

Because both parameters are likely to depend on the size and energetic state of adult mosquitoes, the present study investigates the effects of body size and energy state on attack behaviours in the malaria mosquito, Anopheles gambiae.

Here we report the first Plasmodium GWAS, which included 189 culture-adapted P. falciparum parasites genotyped using a custom-built Affymetrix molecular inversion probe 3K malaria panel array with a coverage of ~1 SNP per 7 kb.

Our results support the inclusion of PvRAP-1 and PvRAP-2 in the design of an antimalarial subunit-based vaccine against P. vivax, which would avoid inducing allele-specific immunity.

Evolutionary dynamics of the immunodominant repeats of the Plasmodium vivax malaria-vaccine candidate circumsporozoite protein (CSP)

To determine whether rearrangements of repeat motifs during mitotic DNA replication of parasites create significant CSP diversity under conditions of low effective meiotic recombination rates, we examined csp alleles from sympatric P. vivax isolates systematically sampled from an area of low malaria endemicity in Brazil over a period of 14 months.
