I'll give you a hint - the organisms look the same as they normally would, but they are not where you would expect them to be.

Schistasoma spp. egg.

Enterobius vermicularis, the famous pinworm. Usually found in the distal rectum/anus. From a Vermonter.

I'd say Enterobius vermicularis as well. They have the classic "wings"

Doesn't Toxocara have lateral alae, too? I thought the "wings" of pinworm were only on the anterior end...

Parasite Gal said...

Tom is right - Toxocara LARVAE also have alae, as do several other nematode larvae. However, E. vermicularis is the only ADULT nematode with lateral alae. Also, the alae (aka wings) are most pronounced at the anterior end, but they can be seen at all levels of the organism in cross-section.
Thanks for making these important points Tom!
