Case of the Week 576

Happy New Year! Our first case of 2020 was provided by Heather Arguello, my awesome Parasitology Technical Specialist. The following worm was found in a specimen obtained during colonoscopy. It measured approximately 2 mm long. Identification?

I know this one. Just cannot seem to pin it down... :P

The general morphology is compatible with Enterovirus vermicularis. The cephalic alae confirms the identity.
A curved tail with visible copulatory spicule defines the nematode being male. For sure it is smaller in size than its female partner.

Overall size, cephalic alae, curved tail with spicula: for sure an adult male pinworm (Enterobius vermicularis -formerly known as Oxyuris vermicularis)! Great photos!
