Case of the Week 560

This week's case is a composite photo I created for my 2019 calendar for the month of September. The accompanying questions are:

  1. What is the parasite shown? (measure ~60 micrometers long)
  2. Why is this a suitable parasite for September?
  3. What is the significance of the other objects in the picture?

Also, visit her website ParasiteWonders.com, which hosts an archive of classic images from cases Dr. Pritt has posted going back to 2007 (in an easy-to-search "A through Z" format) and also offers a flashcard feature.

Answer to Case 560:

"Back to school" pinworm. Eggs of Enterobius vermicularis. See Dr. Pritt's blog for the answer to questions 2 and 3.
