ARTa	48	9	16 ± 2f	6 ± 1.5
ART	48	18	17g	7 ± 1
ART	48	35	NGh	11 ± 2
ART	48*	70	NG	17

^aART, artemisinin.

^bATS, artesunate.

^cThe dose tested corresponds to 10-fold the IC₅₀ of chloroquine (CQ) for F32-Tanzania.

^dAll experiments were carried out at least three times independently except those marked with an asterisk, which were carried out once.

^eValues express the time to reach 5% parasitemia in days ± standard deviations.

^fAt day 21, two of three cultures recovered.

^gAt day 21, only one of three cultures recovered.

^hNG, no growth at day 21.
