Data phylogenetic structure. The phylogenetic tree of the five VSG triplets considered in our study. A total of 15 VSG sequences from the antigen gene archive of African trypanosomes were extracted from the VSG database (http://www.vsgdb.net) and multiply aligned by CLUSTALw. The close relatedness between genes within the same triplet suggests recent divergence from a common ancestor.
