Figure 1

Unrooted neighbor joining tree showing genetic clustering among Trypanosoma cruzi isolates from an outbreak of oral disease in Caracas, Venezuela. Based on pairwise genetic distances (1 − proportion of shared alleles) between multilocus microsatellite profiles (23 loci) generated from 246 isolates and clones. Black circles indicate nodes with >60% bootstrap support. Branch color key is shown. Dashed boxes indicate isolates associated with the oral outbreak.

Figure 1. . Unrooted neighbor joining tree showing genetic clustering among Trypanosoma cruzi isolates from 2 outbreaks of oral disease in northern Venezuela. Based on pairwise genetic distances (1 – proportion of shared alleles) between multilocus microsatellite profiles (23 loci) generated from 246 isolates and clones. Black circles indicate nodes with >60% bootstrap support. Branch color key is shown. Dashed boxes indicate isolates associated with the outbreaks.
