These are usually harmless protozoa, feeding on bacteria . histolytica has a simple, two-stage life cycle, consisting of the infective cyst and colon . histolytica is widely recognized as a pathogen. histolytica has allowed this parasite to become one of the most common human pathogens causing life-threatening infections.Entamoeba histolytica is the responsible parasite of amoebiasis and remains one of the top three parasitic causes of mortality worldwide. Entamoeba histolytica (strain HM-1:IMSS), was the first human amoeba to have its genome sequenced, assembled and analyzed. Pathogenesis appears to result from the potent cytotoxic activity of the parasite, which kills host cells within minutes.
