[i] Based on assemblies where N ≥ 5 ESTs from nonsubtracted libraries. For E. tenella, there were 140 assemblies included; for P. falciparum, there were 203 assemblies included; for T. gondii, there were 568 assemblies included. Two different cutoffs were used, fivefold difference orP ≤ 0.05. NA, not applicable; ND, not done.

[ii] Values expressed as total asssemblies (% of total).
