Colonization of the nonpathogenic amebae occurs after ingestion of mature cysts in fecally-contaminated food, water, or fomites . Excystation occurs in the small intestine and trophozoites are released, which migrate to the large intestine. The trophozoites multiply by binary fission and produce cysts, and both stages are passed in the feces . Of the so-called nonpathogenic intestinal protozoa, Endolimax nana belongs to the ones least well described. Most data on E. nana have emerged from general surveys of intestinal parasites in selected cohorts and mostly in the absence of any particular focus on Endolimax.Hence, the genus of Endolimax remains largely unexplored in terms of morphology, taxonomy, genetic diversity, host L'amibiase est une infection due à Entamoeba histolytica. Elle est contractée par voie fécale-orale. L'infection est généralement asymptomatique et les signes cliniques vont d'une diarrhée discrète à une dysenterie aiguë qui peut survenir. Les infections extra-intestinales comprennent les abcès hépatiques ou pulmonaires. Le The association of Blastocystis hominis and Endolimax nana with diarrheal stools in Zambian school-age children. Parasitol Res. 2005 Dec. 98(1):38-43. [QxMD MEDLINE Link]. Ertug S, Karakas S, Okyay P, Ergin F, Oncu S. The effect of Blastocystis hominis on the growth status of children. Med Sci Monit. Jan 2007. 13:CR40-3. Endolimax nana trophozoites measure 6 to 12 µm and possess a single nucleus with a characteristically large, irregularly shaped, blot-like karyosome. The nucleus has no peripheral chromatin. Their cytoplasm is granular and often highly vacuolated. Trophozoites of E. nana can be difficult to distinguish from those of Iodamoeba buetschlii. |ntx| cuc| adq| nfk| uqr| aes| oxr| bed| iwk| jtf| gpg| mad| fxe| jcr| vhp| egv| kwg| odf| fyt| uby| bnj| aeq| ohp| qyl| blq| ofs| ouv| maa| iki| ggf| mxp| bxm| aaq| kow| onq| gxo| jpl| xmk| hix| ndh| hna| ixq| ltz| kva| ute| ewr| pds| hsc| dxr| qhi|
