Case #482 – December, 2018

A 48-year-old male immigrant from the Middle East underwent a stool examination for ova and parasites (O&P) as part of a refugee screening program. The lab technician observed dark brown-to amber-colored objects in wet mount preparations of formalin-ethyl acetate (FEA) concentrations of the stool sample. The objects measured 41-43 µm in length by 25-28 µm in width. Figures A-D show what was seen in the stool sample.
