Groups were inoculated with clone R in the single infections, or clone R and clone S for the mixed infections. The inoculum of clone S was always 10⁶ parasites, the inoculum of clone R varied from 10⁶ to 10¹ parasites. All treatment groups with an inoculum size of 10¹ parasites had 10 mice at the start of the experiment. All other treatment groups consisted of 5 mice. Drug treatment was given on Days 6–9 post-infection.

^aAn excluded mouse.

^bA dead or euthanized mouse.
