This week's case was generously donated by Drs. Jacob Rattin, Anisha Misra, and Hannah Wang, and originally identified by Marissa Roberts. The following objects were seen on a trichrome-stained stool specimen and measure approximately 15 micrometers in length. What is your identification?

Chilomastix mesnili trophozoite
The sharply pointed tail tells us its identification. A nucleus with eccentric karyosome also points out the commensal Chilomastix mesnili.

Trophozoite of Chilomastix mesnili. It is considered as a non-pathogenic flagellate, but it's presence is an indication of the consumption of contaminated food and/or water.
