Answer to Case 576

Answer to Parasite Case of the Week 576: Enterobius vermicularis (a.k.a., pinworm), adult male

Thanks to all who wrote in with the correct answer. Florida Fan noted the presence of several identifying features: cephalic alae confirming the identity of pinworm in this adult nematode, and the curved tail with visible copulatory spicule defining the gender as male.

Meanwhile, Idzi reminded us that Enterobius vermicularis was formerly known as Oxyuris vermicularis. This is why you will sometimes see the infection referred to as oxyuriasis. Finally, Marc shared that he knew the answer but couldn't seem to "pin" it down 😉.
