A parasitologist's view of the world
Welcome to Parasite Case of the Week
Every week I will post a new Case, along with the answer to the previous case. Please feel free to write in with your answers, comments, and questions. Also check out my image archive website at http://parasitewonders.com. Enjoy!

A mix of Blastocystis species and pollen grains. The overall green color is quite festive.

Blastocystis hominis cyst-like structures.
I assume the query is about the pollen as the Blastocystis cells are not visible in all three images.
Definitely cysts of Blastocystis hominis (in the first picture) and pollen grains -probably of Oleaceae- (in all 3 pictures).
PS: These pollen would make nice Christmas decorations... the nice green color would perfectly match with my Christmas tree!
;-)
Not parasite, pollen?
Blastocystis in the first image and pollen (so beautiful) in all three images.

I think it's all pollen; are the putative Blastocystis in figure 1 really convincing?
Dear colleagues: Dr. Pritt strictly mentioned "10 to 20 micrometers in diameter" in the text. So, don't be misleaded about pollen grains which are much larger in size. Focus on the other smaller structures.
I agree, Blastocystis and pollen (the bigger size, double walls with striate between the walls )in the first picture and pollen in the other picture
Large and green stained cells are geranium pollen cells. Smaller cells are Blastocytis spp. cyst-like forms stained with trichrome. The nuclei in the peripheral cytoplasmic rim are visible, staining purple or red.
The pollen could indeed be from the Geraniaceae as Ozgur suggests. Geraniaceae pollen also have three lobes. Although I would stay with Oleaceae pollen. The lobes of Oleaceae are more rounded. A useful internet link for pollen: https://globalpollenproject.org/Taxon?rank=Family&page=2
I totally agree with Idzi. By the way, thank you for the pollen web link. It's very interesting!

Pollen
I'm no palynologist, but it looks like Brassicaceae pollen to me. A quick image search turned up some very similar grains with size listed as 20 um.

Can you post the case Hx that the parasitology lab images are linked to?
Thank you.

Thank you.
PS: volevo dire che nella prima foto, oltre al polline, c'รจ Blastocystis hominis
