Table 2 Distribution of MSP-1 allelic family in rural and urban communities

From: Extensive diversity in the allelic frequency of Plasmodium falciparum merozoite surface proteins and glutamate-rich protein in rural and urban settings of southwestern Nigeria

  MSP-1 family No. of samples positively amplified Allelic size (bp) Frequency (%) MOI
Rural (n = 151) RO33 11 150–250 7.3 2.8
MAD20 5 150–200 3.3  
K1 4 150–350 2.6  
RO33 + MAD20 4   2.6  
RO33 + K1 3   2.0  
RO33 + MAD20 + K1 124   82.1  
Urban (n = 30) RO33 3 150 10.0 2.6
MAD20 3 150–250 10.0  
RO33 + K1 3   10.0  
RO33 + MAD20 + K1 21   70.0  
  1. Numbers sampled cannot add up since a sample can amplify in more than 1 family
