Antigen detection may be useful as an adjunct to microscopic diagnosis in detecting parasites and to distinguish between pathogenic and nonpathogenic infections. Cysts may not hiistolytica visible in unstained specimens.

Intestinal Amebae

This typical appearance of the nucleus is not always observed as some trophozoites can have nuclei with an eccentric karyosome and unevenly distributed peripheral chromatin. The nonpathogenic Entamoeba disparhowever, is morphologically identical to E.

Entamoeba histolytica life cycle-ru. In these cysts, the glycogen vacuole can be seen as a large, oval refractile body. If the second specimen does not show seroconversion, other agents should be considered. El ser humano se puede contagiar por contacto con las mascotas Fig. Five nuclei are visible in this focal plane.

They are not considered pathogenic, and ibolgico on bacteria and other debris. Image taken at x oil magnification and contributed by the Kansas Department of Health and Environment.

Cysts contain a single nucleus that is not visible in either unstained or iodine-stained wet mounts. In this specimen, at least five nuclei are visible in the shown focal plane.

Notice the bluntly-ended chromatoid bodies. Cysts also contain an inclusion mass of variable size and numerous chromatoid bodies, which may be small and round to large rods with round or splintered ends. Entamoeba gingivalis normally lives in the gingival pockets near the base of the teeth in the human mouth, and may be coughed up in sputum specimens.

Clin Infect DisNov; 29 5 hisstolytica, pp: Differentiation of pathogenic Entamoeba histolytica from other intestinal protozoa by riboprinting.

PLoS OneMaig 26; 11 5pp: The single nucleus is often distorted and irregularly-shaped, with a small to minute centrally-located karyosome. In reference diagnosis laboratories, molecular analysis by PCR-based assays is the method of choice for discriminating between the pathogenic species E. At least one commercial kit is available which detects only pathogenic E.

Trophozoites passed in the stool are rapidly destroyed once outside the body, and if ingested would not survive exposure to the gastric environment. Figure contributed by Assist. Nuclei are usually not visible in unstained specimens. J Clin Microbiol ; Br Heart JAbr; 71 4 histilytica, pp: Specimen from a patient with a liver abscess positive with E.

Because of the protection conferred by their cell walls, the cysts can survive days to weeks in the external environment and are responsible for transmission. Movement in living trophozoites is described as nonprogressive.
