Supplementary Table SIV: Infection with different strains of T. cruzi results in the differences in the transcriptional response at the site of infection. Genes found to be significantly upregulated (FDR<.05 and Fold change >2) in Y strain,Brazil strain or G strain infected skin as compared to mock infected skin were determined. Duplicate genes and genes without descriptions were removed from analysis and gene lists from each strain were compared. Comparisons of gene lists were used to create a venn diagram (Fig. 5A) and the the list of gene descriptions belonging to the following interesections are listed: (A) Intersection of Y, Brazil and G strains, (B) Intersection of Y and G strains only, (C) intersection of Y and Brazil strains only, no genes fell into the intersection of G and Brazil strains only, (D) unique to Y strain, (E) Unique to Brazil strain, (F) Unique to G strain.
