cAMP-Signalling Regulates Gametocyte-Infected Erythrocyte Deformability Required for Malaria Parasite Transmission. [PDF]

, 2015
Blocking Plasmodium falciparum transmission to mosquitoes has been designated a strategic objective in the global agenda of malaria elimination. Transmission is ensured by gametocyte-infected erythrocytes (GIE) that sequester in the bone marrow and at ...

Erythrocyte tropism of malarial parasites: The reticulocyte appeal

Frontiers in Microbiology, 2022
Erythrocytes are formed from the enucleation of erythroblasts in the bone marrow, and as erythrocytes develop from immature reticulocytes into mature normocytes, they undergo extensive cellular changes through their passage in the blood. During the blood

The activity of methylene blue against asexual and sexual stages of Plasmodium vivax

Frontiers in Cellular and Infection Microbiology, 2023
Methylene blue (MB) is an alternative for combating drug-resistant malaria parasites. Its transmission-blocking potential has been demonstrated in vivo in murine models, in vitro, and in clinical trials.

Plasmodium vivax gametocytes and transmission

Parasitology International, 2022
Malaria elimination means cessation of parasite transmission. At present, the declining malaria incidence in many countries has made elimination a feasible goal. Transmission control has thus been placed at the center of the national malaria control programs.

The Coming-Out of Malaria Gametocytes [PDF]

Journal of Biomedicine and Biotechnology, 2010
The tropical disease malaria, which results in more than one million deaths annually, is caused by protozoan parasites of the genusPlasmodiumand transmitted by blood-feeding Anopheline mosquitoes. Parasite transition from the human host to the mosquito vector is mediated by gametocytes, sexual stages that are formed in human erythrocytes, which ...

Can field-based mosquito feeding assays be used for evaluating transmission-blocking interventions? [PDF]

, 2012
A recent meta-analysis of mosquito feeding assays to determine the Plasmodium falciparum transmission potential of naturally infected gametocyte carriers highlighted considerable variation in transmission efficiency between assay methodologies and ...

School-based screening and treatment may reduce P. falciparum transmission

Scientific Reports, 2021
In areas where malaria remains entrenched, novel transmission-reducing interventions are essential for malaria elimination. We report the impact screening-and-treatment of asymptomatic Malawian schoolchildren (n = 364 in the rainy season and 341 in the ...

Risk factors for Plasmodium falciparum gametocyte positivity in a longitudinal cohort. [PDF]

PLoS ONE, 2015
Malaria transmission intensity is highly heterogeneous even at a very small scale. Implementing targeted intervention in malaria transmission hotspots offers the potential to reduce the burden of disease both locally and in adjacent areas.

PfARID Regulates P. falciparum Malaria Parasite Male Gametogenesis and Female Fertility and Is Critical for Parasite Transmission to the Mosquito Vector

mBio, 2022
Sexual reproduction of Plasmodium falciparum parasites is critical to the spread of malaria in the human population. The factors that regulate gene expression underlying formation of fertilization-competent gametes, however, remain unknown.

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission-blocking target. [PDF]

FEBS Lett
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.
