ShareCompartir
A 27-year-old woman who had been working in Laos, Thailand, and Vietnam for one and a half years was visiting relatives in the U.S. While she was in the U.S., she visited a physician for recurring abdominal discomfort, bloating, and frequent bowel movements that she had experienced over the last two months. The physician asked her to submit stool specimens for an ova and parasites examination (O & P). A wet mount preparation was made from a FEA concentration. Figure A, taken at 200× magnification, shows what was seen on the wet mount in low numbers. The size of the object was approximately 135 µm in length. What is your diagnosis? Based on what criteria?
