This study was designed to examine stool specimens of irritable bowel syndrome (IBS) patients for , a common intestinal parasite. One hundred fifty patients were enrolled, 95 IBS cases and 55 controls. These patients provided a medical history, and underwent physical and laboratory evaluations that included stool microscopy and culture for and colonoscopy. The 95 cases (51 males and 44 females) had a mean ± SD age of 37.8 ± 13.2 years. Stool microscopy was positive for in 32% (30 of 95) of the cases and 7% (4 of 55) of the controls ( = 0.001). Stool culture was positive in 46% (44 of 95) of the cases and 7% (4 of 55) of the controls ( < 0.001). Stool culture for in IBS was more sensitive than microscopy ( < 0.001). was frequently demonstrated in the stool samples of IBS patients; however, its significance in IBS still needs to be investigated. Stool culture has a higher positive yield for than stool microscopy.
