title: Parasitic pattern of rodent Plasmodium in blood from mouse tail and from Anopheles blood meal.
abstract: During the course of the infection of mice by rodent malaria parasites (P. yoelii yoelii, P. vinckei petteri, and P. chabaudi chabaudi) the parasitic pattern in the blood smears differed according to the site of sampling: mosquito blood meal (usually actively sucked from capillaries) or mouse tail (issued from larger vessels). There were fewer old trophozoites and mature schizonts, and more immature schizonts, in the mosquito blood meal than in the tail blood of mice. It is suggested that the erythrocyte containing a schizont becomes less rigid when merozoites formation begins. The greater abundance in the mosquito blood meal of the gametocytes infective stage (0-I for P. yoelii, II for P. vinckei), previously shown, could be due to a particular flexibility of this stage, a character progressively selected.
