  • Title: Nonpathogenic Entamoeba dispar quickly outgrows pathogenic Entamoeba histolytica in mixed xenic cultures.

    Journal: Lett Appl Microbiol; 2009 Apr; 48(4):500-3. PubMed ID: 19187490.
    Abstract:
    Entamoeba histolytica and Entamoeba dispar are two microscopically indistinguishable amoebae living in the human colon. The former is a pathogen, whereas the latter is a nonpathogenic commensal. Using a model system of in vitro cocultures and PCR detection of the Entamoeba species, we found that the nonpathogenic species can rapidly outgrow the pathogen in xenic cultures.
