Course of parasitaemia in Cohort 2 monkeys given tafenoquine (TQ) at 6 mg/kg base/day or 2 mg/kg base/day alone or in combination with 16 mg/kg chloroquine base/day for three days. The abbreviation DL refers to the detection limit of parasitaemia by microscopy. For the purposes of illustration parasitaemia levels falling below the limit of detection (approximate location indicated by hashed line) were arbitrarily assigned a value of 1 parasite/μl. Arrows indicate drug administration.
