[New data on the biology of gametocytes of Plasmodium yoelii yoelli gathered from morphological characteristics indicating their age].
A morphological study has been made of the gametocytes of P. yoelii (a parasite of Rodents belonging to the "vivax" group). The authors distinguish 4 types chronologically ordered. Moreover, morphology enables one to predict their infectivity. The morphological analysis represents a tool leading to new data on the biology of gametocytes: loss of infectivity as soon as the parasitaemia becomes high; infectivity restricted to the young stages; concentration of young stages in the blood ingested by the Mosquitoes; short periodicity and short lived infectivity.
