Age-structured gametocyte allocation links immunity to epidemiology in malaria parasites

Malaria Journal, 2007
Background Despite a long history of attempts to model malaria epidemiology, the over-riding conclusion is that a detailed understanding of host-parasite interactions leading to immunity is required.

Plasmodium falciparum gametocyte sex ratios in children with acute, symptomatic, uncomplicated infections treated with amodiaquine

Malaria Journal, 2008
Background Amodiaquine is frequently used as a partner drug in combination therapy or in some setting as monotherapy, but little is known about its effects on gametocyte production and sex ratio and its potential influence on transmission in Africa.

A study of the factors affecting the emergence of the gametocytes ofPlasmodium gallinaceumfrom the erythrocytes and the exflagellation of the male gametocytes

Parasitology, 1956
1. The emergence of the gametocytes ofPlasmodium gallinaceumfrom the erythrocytes and the exflagellation of the male gametocyte were inhibited completely when infected blood was exposed to an atmosphere of 5 % CO2and 95 % O2, or 5 % CO2and 95 % N2. When these gas mixtures were replaced by air, the gametocytes emerged from the erythrocytes and the male ...

Associations between Season and Gametocyte Dynamics in Chronic Plasmodium falciparum Infections.

PLoS ONE, 2016
IntroductionIn a markedly seasonal malaria setting, the transition from the transmission-free dry season to the transmission season depends on the resurgence of the mosquito population following the start of annual rains.

Do the venous blood samples replicate malaria parasite densities found in capillary blood? A field study performed in naturally-infected asymptomatic children in Cameroon

Malaria Journal, 2017
Background The measure of new drug- or vaccine-based approaches for malaria control is based on direct membrane feeding assays (DMFAs) where gametocyte-infected blood samples are offered to mosquitoes through an artificial feeder system.

Probabilistic data integration identifies reliable gametocyte-specific proteins and transcripts in malaria parasites. [PDF]

, 2018
Plasmodium gametocytes are the sexual forms of the malaria parasite essential for transmission to mosquitoes. To better understand how gametocytes differ from asexual blood-stage parasites, we performed a systematic analysis of available 'omics data for ...

Parasitaemia and gametocytaemia after treatment with chloroquine, pyrimethamine/sulfadoxine, and pyrimethamine/sulfadoxine combined with artesunate in young Gambians with uncomplicated malaria. [PDF]

, 2001
As part of a study to assess the infectivity of gametocytes after treatment with four antimalarial regimens, the efficacy of each treatment was also determined.

Gametocytes, sporozoites and liver schizonts.

South African medical journal = Suid-Afrikaanse tydskrif vir geneeskunde, 1974
Plasmodium falciparum differs from other human species of Plasmodium in the short, limited exo-erythrocytic stage in the life cycle, which is an apparent disadvantage in surviving through a prolonged non-transmission season such as occurs throughout much of tropical Africa.

Genotyping Plasmodium falciparum gametocytes using amplicon deep sequencing

Malaria Journal
Background Understanding the dynamics of gametocyte production in polyclonal Plasmodium falciparum infections requires a genotyping method that detects distinct gametocyte clones and estimates their relative frequencies. Here, a marker was identified and
