Case of the Week 427

Welcome back for the last case of 2016!

I thought I would close out the year with an old favorite. The case and beautiful images are donated from George at MSKCC. The specimen is concentrated stool from a young child.

Identification of the 2 worms shown here?

Indeed, the first two pictures are consistent with E. vermicularis male, judjing by the cephalic alae and curved tail, some what blunt terminally due the copulatory structures.
The following three are consistent with E. vermicularis female, again we can clearly see the cephalic alae and a clear caudal portion.
