  1. Note: A 100% match to a sequence does not necessarily indicate that this is the species detected. The amplicon sequenced is sufficient for a species diagnosis for only some parasites. Please refer to Fig. 5 for details
  2. aDemodex are mites that commonly inhabit the pores in normal human skin and are considered non-pathogenic, we suspect that this represents potential contamination with skin debris from the venipuncture site. T. cruzi was not detected in this specimen
  3. bExamples where multiple hits to the same accession were observed. These are both shown because the percentage similarity to these accessions is different for these two haplotypes
