Proteome analysis of excretory-secretory proteins of Entamoeba histolytica HM1:IMSS via LC–ESI–MS/MS and LC–MALDI–TOF/TOF

Background Excretory-secretory (ES) proteins of E. histolytica are thought to play important roles in the host invasion, metabolism, and defence. Elucidation of the types and functions of E. histolytica ES proteins can further our understanding of the disease pathogenesis. Thus, the aim of this study is to use proteomics approach to better understand the complex ES proteins of the protozoa.
