Allelic diversity of the C-terminal fragment of Pf MSP-1
in Plasmodium falciparum populations in Thailand. Sampling sites were at the borders of Thailand and three neighboring countries: Ubon Ratchathani (U), located at the Laos-Thailand border, Trat (T), located at the Cambodian-Thailand border, and Mae Hong Son (M), Kanchanaburi (K) and Ranong (R), located at the Myanmar-Thailand border. Numbers (n) of the total parasite isolates in Thailand (overall) or the parasites from each locality are displayed in the bracket. Numbers in pie charts represent the percentage of each MSP-119 haplotype (E/KNG/L, dark blue; Q/KNG/L, red; E/TSR/L, green; E/TSG/L, purple; QKNG/F, light blue).
