Randomized trial evaluates drug resistance impacts on fitness in malaria parasites, suggesting fitness costs may limit resistance spread.

This research aims to understand how drug resistance in malaria parasites affects their fitness and implications for treatment.
Characterization of resistance-mediating polymorphisms in malaria parasites
In vitro and in vivo studies examining the growth of resistant strains compared to wild type
Analysis of clinical samples under different selective pressures
Resistance mutations generally lead to reduced growth in culture and animal models compared to wild type.
Wild type parasites often replace resistant strains when drug pressure is reduced.
Potential compensatory mutations may enhance virulence or transmission despite fitness costs.

Philip J. Rosenthal (2013) studied this question.
