Plasticity and genetic variation in traits underpinning asexual replication of the rodent malaria parasite Plasmodium chabaudi

摘要

BackgroundThe ability of malaria (Plasmodium) parasites to adjust investment into sexual transmission stages versus asexually replicating stages is well known, but plasticity in other traits underpinning the replication rate of asexual stages in the blood has received less attention. Such traits include burst size (the number of merozoites produced per schizont), the duration of the asexual cycle, and invasion preference for different ages of red blood cell (RBC).
