Case #210 – August, 2007
A 32-year-old man went to his health care provider with complaints of bloating, intermittent diarrhea, and abdominal cramping. He stated he liked to go camping and hunting and sometimes consumed the fish and game that he caught. The man was asked to provide a stool specimen for testing. The laboratory that performed the testing made a wet mount after using a concentration procedure. Figures A and B show what was observed in low numbers on the slide. The objects ranged in size from 45 to 58 micrometers in diameter. What is your diagnosis? Based on what criteria?
