Leishmania braziliensis causing human disease in Northeast Brazil presents loci with genotypes in long-term equilibrium
Fig 5
L. braziliensis individuals contribute similarly to putative subpopulations predicted by Structure, based on their genotypes in CHR24/3074 and CHR28/425451 loci, in Corte de Pedra.
Structuralization within Corte de Pedra’s L. braziliensis population into discrete subpopulations was assessed using the software STRUCTURE [21]. The analyses were performed using combined data of CHR24/3074 and CHR28/425451 loci. Two conditions were tested: (A) structuralization into two subpopulations, i.e. K = 2; and (B) structuralization into 20 subpopulations, i.e. K = 20. Histograms show the proportional contributions of each individual in the overall sample to each theoretical subpopulation ordered by sampling period (i.e. 1999–2001 and 2008–2011) after a burn-in step of 10,000 runs followed by 100,000 MCMC replications of the data.
