They are then accessible to mosquitoes, which can ingest them when they bite (see the top of the image on page 2). But circulating erythrocytes -- whether they are gametocyte-infected or not -- are deformable, thus preventing their clearance via the spleen, which constantly filters the blood and only retains stiff, old or abnormal erythrocytes. However, gametocyte-infected erythrocytes can easily pass through the spleen and persist for several days in the blood circulation.
