Photograph showing the resolution of amplified products of msp1, msp2, and glurp allelic families of the six patients with recurrent infections. a Patient 1 had identical msp1-K1, msp1-RO33, msp2-FC27, and glurp alleles. b Patient 2 had alleles of all msp1 and msp2 allelic families in the initial sample, while the recurrent sample had only an msp1-K1 allele and an msp2-FC27 allele. c The recurrent infection of patient 3 had identical msp1-RO33 and msp2-3D7, and msp2-FC27 alleles and additional new msp2-FC27 alleles. d Patient 4 shared msp1-K1, msp2-3D7, and shared glurp in the initial and recurrent samples. e Patient 5 has similar msp1- K1 and msp1-MAD 20 alleles. Shared alleles were seen in msp2-FC27 and msp2-3D7. Glurp fragments were present in both samples. f Patient 6 had msp2-3D7 and msp1-K1 alleles in the initial sample while the recurrent sample on D105, had different msp2-3D7 and K1 alleles and faint bands of additional msp1-RO33 and msp1-MAD20 alleles indicating a reinfection
