These were all retrieved through a formalin-ether concentration technique. The feces were collected from stray cats (Felis catus) through enema.
The first three eggs are around 35-40 µm while the fourth one is around 60. The fifth one is around 40-45 µm as well
Our guesses are (from top to bottom):
1 and 2 - Toxascaris leonina (but they're too small)
3 - I think they have polar plugs but are reeaaally small
4 - Diphyllobothrium latum
5. Toxocara cati (but again, it's quite small)
Some insight about it could be really helpful. Thanks in advance :)
Eggs 1 and 2 are not from Toxocara, for sure. These are Toxocara leonina eggs (https://en.wikipedia.org/wiki/Toxascaris_leonina#/media/File:A_toxascaris_leonina1.JPG).
All of them seems to be trematode eggs, but I'm not sure about the parasite genus.
Dear Karl Patrick,
In my opinion, photos 1, 2, 3 and 5 correspond to eggs of Platynosomum illiciens (=P. fastosum). Photo 3 can be an infertile egg of this parasite.
On the other hand, photo 4 probably corresponds to a diphyllobothridean cestodes , maybe a species of Spirometra.
Best regards,
Hudson
On my opinion photo 1,2 and 5 are eggs of Platynosomum illiciens; no.3 and 4 are Spirometra eggs
Hi, i dont think that they are toxocara eggs, you can see the figures of my master thesis in this site.
Dear Dr. Karl, may be useful to look at this paper:

The fourth one maybe the eggs of Fasciola hipatica. It has a significant operculum. Hope it can help you.
Best wishes.
