Children often tease each other “na,na,na,na,na,na”, definitely a rare find when the whole dwarf tape worm is expelled in the stool. More often we find it’s eggs. The egg is small, ovoid in shape and has polar filaments, the confirmation of Hymenolepis nana is guaranteed.

Hymenolepiasis nana eggs and adult with scolex and proglottids .
Wow, awesome work
It is the person behind the scope
I would measure up, too
I posted somewhere (can find my original post) that it was a Taenia sp., however after someone pointed out the egg to me. Its definitely not. I think its a Hymenolepis sp. favor dilminuta becuase I don’t see polar filaments. Measurements of the egg would help the ID.
