The extraordinary phagocytic activity of<jats:italic>E. histolytica<\/jats:italic>trophozoites has been accepted as one of the virulence mechanisms responsible for their invasive capacity. The recognition of the noninvasive<jats:italic>Entamoeba dispar<\/jats:italic>as a different species has raised the question as to whether the lack of pathogenic potential of this ameba correlates with a limited phagocytic capacity. We have therefore compared the process of erythrophagocytosis in both species by means of light and video microscopy, hemoglobin measurement, and the estimation of reactive oxygen species (ROS). In the present study, we confirmed that<jats:italic>E. dispar<\/jats:italic>has lower erythrophagocytic capacity. We also observed by video microscopy a new event of erythrocyte opsonization-like in both species, being more characteristic in<jats:italic>E. histolytica<\/jats:italic>. Moreover,<jats:italic>E. dispar<\/jats:italic>showed a lower capacity to produce ROS compared with the invasive species and also showed a large population of amoebae that did not engulf any erythrocyte over time. Our results demonstrate that<jats:italic>E. histolytica<\/jats:italic>has a higher phagocytic capacity than<jats:italic>E. dispar<\/jats:italic>, including a higher rate of production of ROS in the course of ingesting red blood cells.<\/jats:p>","DOI":"10.1155\/2014\/626259","type":"journal-article","created":{"date-parts":[[2014,6,5]],"date-time":"2014-06-05T21:07:45Z","timestamp":1402002465000},"page":"1-10","source":"Crossref","is-referenced-by-count":26,"title":["Erythrophagocytosis in<i>Entamoeba histolytica<\/i>and<i>Entamoeba dispar<\/i>: A Comparative Study"],"prefix":"10.1155","volume":"2014","author":[{"given":"Daniel","family":"Talam\u00e1s-Lara","sequence":"first","affiliation":[{"name":"Department of Infectomics and Molecular Pathogenesis, Center for Research and Advanced Studies, IPN, Avenida Instituto Polit\u00e9cnico Nacional No. 2508, Colonia San Pedro Zacatenco, Delegaci\u00f3n Gustavo A.
