Case #466 – April, 2018

A 6-year-old girl, who originally lived in Japan but now resides in the United States, was seen by a health care provider for abdominal pain and diarrhea. A stool specimen was collected and the object shown in Figure A was observed in the specimen. It was sent to the CDC DPDx Team for identification. The object was cleared using lacto-phenol and Figure B shows what was observed using a dissecting microscope. What is your diagnosis? Based on what criteria? Would you suggest any other test(s)?
