Origin of collected Plasmodium falciparum isolates. This world map presents the number of isolates and their approximate origin (d-maps.com©). From 1978 onwards 121 isolates derived from patients with clinical symptoms were collected by the Radboudumc (depicted by asterisk) and stored in liquid nitrogen. The origin of three isolates, previously published by the Radboudumc, is shown in text (NF54, NF135 and NF166). For 32 collected isolates the origin was unknown and for 5 isolates uncertain (not shown in figure)
