Malaria parasites have evolved flexible strategies to cope with the changing conditions they experience during infections. We show that using such flexible strategies does not impact upon the parasites’ ability to grow (resulting in disease symptoms) or transmit (spreading the disease).

Comparing the degree of synchrony across species, strains, and time points within infection can illuminate the proximate and evolutionary drivers of synchrony. Standardized methods for comparing synchrony are lacking and may suffer from multiple sources of bias, highlighting an urgent need for better approaches

Parasites alter how much effort they invest in survival versus reproduction, according to changes in their in-host population size. When population sizes plummet, parasites prioritise between-host transmission. However, smaller losses in number elicit reproductive restraint, which facilitates in-host survival and future transmission.

At night, gametocytes are twice as infective to mosquitoes, despite being less numerous in the blood. Enhanced parasite infectiousness at night interacts with mosquito circadian rhythms to increase sporozoite burdens fourfold when mosquitoes become infected from feeding during their rest phase.
Comment on Koepfli et al (2018) to highlight the potential for parasites in natural infections of humans to adjust their investment in gametocytes during infections.

Reveals that the malaria parasite Plasmodium chabaudi responds to host anaemia by increasing investment in transmission stages because, counterintuitively, host aneamia represents a better environment for parasite replication. Furthermore, evolutionary potential in form of genetic variation exists in the extent that parasite strains respond to changes in red blood cell resources.

Reveals that, contrary to expectation, parasites do not preferentially invest into transmission when mosquitos are available to vector them.

Demonstrates that traditional methods for sexing male and female transmission stages can overestimate the proportion that are females and quantifies sex-specific mortality rates.

Develops theory to predict how parasites should invest in male versus female transmission stages according to the fecundity of males and overall numbers of sexual stages.
