**: From [22]; NF = not found; troph = trophozoite; expr = expression; N/A = Not applicable; shown in bold fonts are those that show 90% or less identity with E. dispar proteins; ideal candidates for E. histolytica specific diagnostic tool development. NB. None of the proteins listed in Table 2 could be detected in any of the 4 trophozoite-specific proteome datasets available at the AmoebaDB or EST datasets (as of February, 2012).
