Median joining network analysis of P. falciparum samples collected in Iquitos in (a) 1998–2001 and (b) 2003–2005.
The genetic relationships among parasites were constructed using the seven neutral microsatellite loci shown on Table 2. The distinct lineages are rendered in different colors and circle sizes are proportional to the number of samples assigned to a particular lineage. The number of samples assigned to each lineage by Structure analysis are shown in parentheses.
