Welcome to the first blog post of 2024! I had been particularly busy last year as I was serving as the Interim Chair of the Department of Laboratory Medicine and Pathology at Mayo Clinic. Now that the permanent Department Chair has arrived, I can go back to my 'day job' of Chair of Clinical Microbiology and Director of the Clinical Parasitology laboratory. I anticipate being able to go back to regular posting again as well.
So without further ado, here is our case this week, courtesy of Heather Morris, the Parasitology Technical Specialist in my laboratory. The following objects were found in a concentrated wet preparation of stool, and measure approximately 20 micrometers in diameter. No patient history is available. What is your identification?

Entamoeba coli
E. Coli cyst
For sure this is a classic case. Size wise, the object is way larger than the 12 micron diameter of E. Hartmani. We can also count more than four nuclei present, this rule out any chance of E. histolytica/dispar. The remaining possibility is E. coli cyst. In addition, the karyosome is fairly large.
