Answer to Case 373

Answer: pinworm eggs - with a newly emerging larva. Kudos to Felicity in my lab for catching this worm in action!

Note the range of eggs seen here, including a classic oval/elliptical eggs with flattened side, an egg containing a larva, and lastly, the emerging larva.

And here's a poem from Blaine!

So many nematodes in the gut, it’s hard to tell which is which
But Enterobius vermicularis fulfills a particular niche
For she likes to come out at night
And oviposit at the site
That is sure to make your booty itch!
