I believe that the other non-pathogenic Entamoeba species can also do this. The U.S. CDC now has the following on their website to reflect this: "While the discussed species are morphologically-identical, E. histolytica may be observed with ingested red blood cells (erythrophagocytosis); E. dispar may occasionally be seen with ingested erythrocytes as well, although its capacity for erythrophagocytosis is much less than that of E. histolytica." Here is one study that I found from just a quick internet search: https://www.hindawi.com/journals/bmri/2014/626259/<br /><br />We can ask Dr. Graham Clark from LSHTM for more information if you are interested.

I thought that RBC's moving withing the amoeba is pathognomonic feature of E. histolytica. So I'm happy to learn which other Entamoeba species can also do this.
