Editor's Notes

  • #3 Co- Authors: M. Arcari 1, A. Baxendine 1 and C. E. Bennett2 Volume 3. The Flagellates, University of Southampton, 'Ectoparasites and Endoparasites' 1. A flagellated protozoan that lives in the intestine of humans. 2. Enteromonas hominis is a small flagellate and is rarely encountered in man. It is found in both warm and temperate climates and is considered to be non-pathogenic.
  • #4 1. The trophozoites are oval and 4-10m m in length. They have 4 flagella, 3 anterior flagella and one adheres to the body ending in a tail, producing a jerky rotational movement. They have one nucleus with a large karyosome that is evident in a stained preparation. 1. The cysts are oval and range between 6-8m m in length. They have up to 4 nuclei with a bipolar tendency.
  • #5 Both cysts and trophozoites of Enteromonas hominis are shed in feces The number 1. Infection occurs after the ingestion of cysts in fecal-contaminated food or water, or on fomites The number 2. In the large (and possibly small) intestine, excystation releases trophozoites. Enteromonas resides in the large intestine, where it is regarded as a commensal and is not known to cause disease. Infection occurs after the ingestion of cysts in fecal-contaminated food or water, or on fomites (inanimate objects or substances capable of transferring pathogens).
  • #6 Clinical Presentation Enteromonas hominis is considered nonpathogenic. The presence of cysts and/or trophozoites in stool specimens can however be an indicator of fecal contamination of a food or water source, and thus does not rule-out other parasitic infections.
