	Abstract

Entamoeba histolytica, the cause of amebiasis, is believed to have no continuous endoplasmic reticulum (ER), with ER functions occurring in vesicles. Here, using an ER-targeted GFP-fusion protein and fluorescence loss in photobleaching (FLIP), we have unambiguously demonstrated the presence of a continuous ER compartment in living E. histolytica trophozoites.
