FIG. 4.

LDR-FMA diagnosis of 921 patient samples at dhfr codon 59 (A) and pfcrt codons 72 to 76 (B). Results from the multiplex LDR-FMA show fluorescence captured for two alleles simultaneously for each individual sample: 59C and 59R for dhfr and CVMNK and SVMNT for pfcrt. Data points on the x or y axis suggest single infections with parasites carrying dhfr 59C or 59R, respectively (A), or pfcrt CVMNK or SVMNT, respectively (B). Data points occurring off the x and y axes suggest that infections included a mixture of parasites carrying both alleles.
