Answer to Case 579

Answer toParasite Case of the Week 579:Entamoeba histolyticaThis great case by Idzi nicely shows the directional motility of anE. histolyticatrophozoite - something that is less commonly seen in the clinical laboratory as more fecal specimens are received in a fixative. This case also highlights the characteristic ingestion of red blood cells (erythrophagocytosis) by the trophozoites.Dr. Graham Clark reminds us that non-pathogenic Entamoebaspecies may also ingest red blood cells that are in the environment, so correlation with clinical presentation, biopsy, antigen and/or PCR tests is also warranted.
