OK
Entamoeba histolytica is an anaerobic parasitic amoebozoan, part of the genus Entamoeba.[1] Predominantly infecting humans and other primates causing amoebiasis,
Amoebiasis, the third most common cause of
parasitic parasitic death in the world is caused by Entamoeba histolytica protozoa with
pseudopodia.
E. histolytica has two stages:
– trophozoite and
– cyst with an intermediate
– precyst.
The trophozoite is the actively
metabolizing, motile stage, and the
cyst is dormant and environmentally
resistant
Morphology of cyst
The cyst is spherical,10-20 µm in diameter, with a
thin transparent wall.
Fully mature cysts contain four nuclei. The nuclei
have fine evenly distributed uniform granular
peripheral chromatin, with small discrete central
karyosome.
Chromatoidal bars, crystallized
ribonucleoproteins, are present variably, and are
more common in immature cysts. They are
elongated bars with bluntly rounded ends.
Inclusions in the form of glycogen masses also
may be present. Usually diffuse, concentrated
masses often present young cysts. They stain
reddish brown with iodine

Asymptotic cyst passers are individuals that passes trophozoites that are found in the infected stools.
Explanation:
- The amoeba of pathogenic type, Entamoeba histolytica is related to the infections of intestine and extra intestine.
- The infection that takes place by this genus occurs due to the consumption of cysts of contaminated foods.
- The cyst and trophozoites are excreted by the stool. Trophozoites are passed by the infected stool.
- They are passed by the person who has infection in intestine, known as ‘asymptotic cyst passer’.
- In this individual trophozoites are restricted to the lumen of intestine and make the individual to pass cyst through their stool.
