A pollen grain ?

Best regards

or a tapeworm egg?

mostly pollen grain

can you take another pic with high power

Did you see more like that? How much? and What is the biology sample from human?

Best,

the biological sample is stool as mentioned 

Entamoeba cyst

It is an artifact.

Objects looking more or less like that can be plant-derived. This comment is "limited" by the clarity of the picture.

agreed it looks like a pollen gain.

It is not a parasite

This structure is a pollen grain. Some types of pollen grains are closely similar to the eggs of Taenia species. The major clues for differentiation are as follows:

- Pollen grains lack the characteristic hooklets of the inner onchosphere.

- The outer shell lacks the characteristic radial striations of the embryophore.

Therefore, the above structure is simply an artifact.

I agree with  Rashad Abdul-Ghani! Definitely a pollen grain! The shell of Taenia eggs would also be more dark brownish in color.

I agree with Rashad Abdul Ghani

I agree with the opinion of Dr. Rashad Abdul-Ghani.

Resembles Hymenolepis nana but it  Is definitely not a parasite, but a pollen or a not totally digested plant body.

I've viewed the picture at higher magnification ("accidentally" clicked on it), and it is actually quite clear, in contrast to when I saw it initially. Apart from being unlike the eggs of helminth parasites of humans, the structure does not resemble, either, any of the domestic animal helminth eggs (very rarely, they can be present in human faeces following accidental ingestion) with which I am familiar (for research-related reasons), nor any protozoan cysts (these being smaller than helminth eggs, of course; and this object seems "large"), including unsporulated coccidian oocysts (Cystoisospora, Eimeria, etc.). The latter group of organisms have thin "walls" in comparison. Thus, it is not a Naegleria or other amoebic cyst ("wall" too thick). The closest that the morphology of the object comes (leaving aside the matter of its exact size) is to Taenia and Hymenolepis. Compatible with comments made by Rashad, Patrick, Idzi and Gholam, the structure does not have inter alia the characteristic radially striated wall or often brownish appearance of a Taenia egg, nor are hooks visible in the middle (cf. Taenia and Hymenolepis). It has the typical appearance of a plant-derived artifact, like a pollen grain.

Thank for all

I appreciate your valuable comments

 This is an artifact because it is not bile stained as Taenia egg and not striated. 

hi this not parasite , this is pollen grain
