Lewenssiklus van Entamoeba histolytica’n eensellige, anerobiese, parasitiese protozoaan, wat in die eerste stadium mense aanval en Amoebiase veroorsaak.

Cysts contain a single nucleus that is not visible in either unstained or iodine-stained wet mounts. Recent studies indicate improved sensitivity and specificity of fecal antigen assays with the use of monoclonal antibodies which can distinguish between E.

Entamoeba histolytica este un protozoar anaerob parazit din genul Entamoeba. Bull World Health Organ; 40 3pp. Los trematodos tienen un ciclo vital complejo, dentro del cual parasitan a varios hospederos vertebrados e invertebrados; los huevos pasan del hospedero a las heces y una vez que llegan a aguas dulces eclosionan en larvas nadadoras libres, llamadas miracidios, las que penetran en un hospedero intermediario como el caracol, la almeja u otro molusco, para cidlo en esporocistos en su interior.

Mature cysts contain four nuclei that possess a small, discrete centrally-located karyosome and evenly-distributed peripheral chromatin.


Trophozoites passed in the stool are rapidly destroyed once outside the body, and if ingested would not survive exposure to the gastric environment.

Endolimax nana cysts in concentrated wet mounts. World J GastroenterolMar 1; 10 5pp: This figure and Figure E represent the same cyst shown in two different focal planes.

Trophozoites possess a single nucleus that contains a small, centrally-located karyosome and fine peripheral chromatin. Movement in living trophozoites is described as nonprogressive.

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. Parasitol ResJun; 90 2pp: L’aurofina un compost de sals d’or utilitzat en el tractament de certs tipus d’ artritis reumatoidemostra in vitro i in vivo una alta activitat contra E.

There is no known cyst stage for Entamoeba gingivalis ; trophozoites live in the oral cavity of humans, residing in the gingival pockets near the base of the teeth. Nuclei are usually not visible in unstained specimens.

Cysts are typically found in formed stool, whereas trophozoites are typically found in diarrheal stool. In reference diagnosis laboratories, molecular analysis by PCR-based assays is the method of choice for discriminating between the pathogenic species E. FResOct 26; 5, pp: PLoS PathogOct 20; 12 10pp: Aten PrimariaMar 31; 35 5pp: Although this mass can be visible in unstained wet mounts, in iodine-stained preparations it takes on a darker, reddish-brown color.
