Table 2 Diversity of msp1 and msp2 in samples from Papua New Guinea and Tanzania

From: Comparison of Plasmodium falciparum allelic frequency distribution in different endemic settings by high-resolution genotyping

  Papua New Guinea Tanzania
  msp2 msp1 msp2 msp1
Number of samples (n) 108 108 115 115
Number of alleles 35 24 76 29
Frequency of most common allele 15.08% 16.28% 11.21% 20.57%
Number of clones 199 215 428 350
Mean MOI* 1.84 1.99 3.72§ 3.04§

  1. * MOI = mean multiplicity of infection
  2. ** HE = expected heterozygosity. This is defined as the probability that two randomly chosen alleles are different in the population.
  3. *** The combined probability that two independent clones share the same genotype for both marker genes was calculated by multiplying the probabilities P for both marker genes.
  4. § Indicates significant difference between mean MOI of msp1 and msp2 (p < 0.001)
