Strategies for Detection of Plasmodium species Gametocytes

Strategies for Detection of Plasmodium species Gametocytes

Carriage and density of gametocytes, the transmission stages of malaria parasites, are determined for predicting the infectiousness of humans to mosquitoes. This measure is used for evaluating interventions that aim at reducing malaria transmission. Gametocytes need to be detected by amplification of stage-specific transcripts, which requires RNA-preserving blood sampling. For simultaneous, hig...

Developing Gametocytes and Schizonts of Plasmodium Falciparum

The following is the description ol' plate XXII (figures 1 to 16) illustrating the article on Developing gametocytes and schizonts of Plasmodium falciparum ; A case showing all stages in the peripheral circulation', by B. M. Das Gupta and S. K. Ganguli, published in the October issue of the Gazette (p. 458) which was, by error, omitted. Figures 1 to 7 developing crescents, 6 and 7 showing two i...

Gametocytes of Plasmodium falciparum in the megakaryocytes

which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. A 50-year-old woman presented with fever for 1 week, with mild splenomegaly and anemia. Hematological examination showed pancytopenia, but peripheral blood smear examination showed no evidence of parasite. Because of pan-cytopenia, the patient was subjected ...

Out-of-phase circadian biorhythms in gametocytes of Plasmodium falciparum

The individual circadian periodicity in eight hosts of Plasmodium falciparum gametocytes is studied in Senegal. The average time series does not present any periodicity. As for filariasis (Pichon and Treuil, 2004), it could be considered that this lack of global periodicity is in fact due to the coexistence, in each host, of two completely periodic, out of phase rhythms. Here we propose a simpl...
