Plasmodium falciparum

Investigation of volatile organic biomarkers derived from Plasmodium falciparum in vitro

Reference: 
Malaria Journal 2012, 11:314 (7 September 2012)

MalariaWorldFuture in vivo studies analysing the breath of patients with severe malaria who are harbouring a parasite biomass that is significantly greater than achievable in vitro may yet reveal specific clinically-useful volatile chemical biomarkers.

Optimization of flow cytometric detection and cell sorting of transgenic Plasmodium parasites using interchangeable optical filters

MalariaWorldFilter optimization is particularly important for applications where the FP signal and percentage of positive events are relatively low, such as analysis of parasite-infected samples with in the intention of gene-expression profiling and analysis.

MalariaWorldThe results show that implementing volunteer programmes to improve the coverage of accurate and timely diagnosis with RDT and early treatment may be beneficial but the timeliness of detection and sustainability must be improved.

Malaria resistance genes are associated with the levels of IgG subclasses directed against Plasmodium falciparum blood-stage antigens in Burkina Faso

Afridi S, Atkinson A, Garnier S, Fumoux F, Rihet P
Reference: 
Malaria Journal 2012, 11:308 (4 September 2012)

MalariaWorldTaken together, the results support the hypothesis that some polymorphisms affect malaria resistance through their effect on the acquired immune response, and pave the way towards further comprehension of genetic control of an individual's humoral response against malaria.

Analysis of the trap gene provides evidence for the role of elevation and vector abundance in the genetic diversity of Plasmodium relictum in Hawaii

Farias ME, Atkinson CT, LaPointe DA, Jarvi SI
Reference: 
Malaria Journal 2012, 11:305 (3 September 2012)

MalariaWorldThe results of this study suggest that pathogen diversity in Hawaii may be driven by a complex interaction of factors including transmission rates, host immune pressures, and parasite-parasite competition.

Not Open Access | A single amino acid change in the Plasmodium falciparum RH5 (PfRH5) human RBC binding sequence modifies its structure and determines species-specific binding activity

September 3, 2012 - 14:05 -- Patrick Sampao
Author(s): 
Gabriela Arévalo-Pinzón, Hernando Curtidor, Marina Muñoz, Manuel A. Patarroyo, Adriana Bermudez, Manuel E. Patarroyo
Reference: 
Vaccine, Volume 30, Issue 3, 11 January 2012, Pages 637-646

MalariaWorldOur results show that a single amino acid change in the HABP 36727 sequence modifies a peptide's 3D structure, thereby resulting in a loss of specific binding to human RBCs and its inhibition ability, while binding to Aotus RBC remains unmodified.
