Answer to Case 493

Answer: Enterobius vermicularis adult female and eggs (containing viable larvae). I hope you all got to see the beautiful video of 'baby's first steps' (or wriggles?) that Idzi provided showing a larva hatching from an egg.

The diagnostic features include prominent cervical alae, bulbous esophagus, pointed 'pin-like' tail, and "D" shaped eggs, with flattening on one side.


As Florida Fan mentioned, Blaine did a fabulous job replicating these eggs in his Halloween costume last year.

AND, he left some presents behind!

Ha ha! You found some of the 'presents' I left behind! I was trying to demonstrate how easily transmitted this helminth is :-D
