We are approaching the 250th Case! I think that #250 should be extra special and therefore I will be looking through all of my archives for something really fun. If any of you have any suggestions for a case you'd like to see, please let me know and I'll see what I can do.
Now, on to this week's case, donated by Florida Fan:
(a bit of a challenging case)
The following were seen in a stool specimen from a 3 year old male. No other history was provided. Identification? The images were taken at 40x magnification, so each each mark on the scale bar represents 2.5 microns (eggs measure approximately 100 microns in length by 50 microns in width).
Identification?

Texas fan: Artifact..very big for Ascaris or Taenia egg
Ascaris definitely!
Macracanthorhynchus hirudinaceous eggs.
All time favorite parasite name:
Macracanthorhynchus.
Your poetry guy should get extra credit if he can use this word in a limerick!
Macracanthorhynchus hirudinaceus eggs
Macracanthorhynchus spp. eggs
I am impressed, not so sure you can separate from M. ingens??
LOL! I cheated, but did find this on both the CDC site and in my vet. parasite book. I look forward to learning more about this.

I don't know how to differentiate between the species but I dare to say that I think the kid probably ate a beetle rather than a millipede, so I bet for de M. hirudinaceus.
"but I dare to say that I think the kid probably ate a beetle rather than a millipede, so I bet for de M. hirudinaceus."
I have to agree with you there!
