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

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