Popis: Many active flagellates were detected in stool samples of a 22-year-old Japanese male who traveled China and India. Microscopic observation showed that the organisms stained with Wright's solution were pyriform or rounded in shape, measuring 11.7-17.5 pm in length and 7.9-f2.2 pm in width. The posterior end was pointed. Three free anterior flagella were located in the front end. A spherical nucleus was situated near the anterior pole. Based on these morphological features we identified the organisms as trophozoites of Chilomastix mesnili, a common intestinal protozoon. Although we examined viral, bacterial and parasitic infections other than C.mesnili, no pathogen was found. From these results obtained, it was considered to be highly probable that C. mesnili infection was the cause of the diarrhea.
