Because reverse transcription-PCR methods for detection of gametocytes
have documented higher rates of gametocyte
infection than microscopy (22,23), we are developing this testing method in our laboratory to confirm the absence of gametocytemia in the most recent samples from study participants.
The epidemiology of Plasmodium falciparum gametocytes
: weapons of mass dispersion.
After a few cycles of asexual stages, some of the infected erythrocytes differentiate into gametocytes
, and once ingested by the mosquito through a blood meal, undergo fertilization generating an oocyst.
Parasite densities were calculated by counting the number of asexual parasites per 200 leukocytes, assuming a leukocyte count of 8,000/[micro]L, and the presence of gametocytes

," Journal of Theoretical Biology, vol.
In parallel, stress factors such as lack of nutrition and host immune pressure force merozoites to develop into gametocytes
. Finally, the cycle continues when Anopheles mosquito ingests blood containing gametocytes
Timely diagnosis and treatment do not only help to prevent hospitalizations and deaths, but also help to control disease transmission by preventing or reducing the appearance of the sexual stages of the parasite (gametocytes
) in human hosts, the infective forms to the mosquito vectors (4, 6).
Many treatments (even some that are not permanently gonadotoxic) can trigger transient changes in in gametocyte
DNA, along with changes in number and function.
Despite this, through the observations, Plasmodium falciparum prevalence and gametocyte
rate in villagers decreased dramatically after LLINs deployment (61).
