Subtle inflammation, especially after infectious enteritis, has been sometimes suspected as one mechanism of pathogenesis. This research was performed (1) to evaluate the prevalence parasitic infections and (2) possible association IBS infections. Fifty-nine patients were recruited using symptom-based criteria (Rome Criteria II) an absence intestinal infection by direct smear method. Stool samples individual examined 7 methods, ie examination for stool occult blood, simple saline method, formalin-ether technique, culture Blastocystis hominis, modified trichrome stain, Ziehl-Neelsen stain bacterial Of 59 patients, 13 (22.1%) positive parasites. These B. hominis (13.6%), Strongyloides stercoralis larvae (1.7%), Giardia lamblia cysts non-pathogenic protozoa, Endolimax nana (5.1%). The rate control group (20%) not statistically different from patients. There no statistical difference between found this study (p = 0.87). In group, predominated while other 8.5%. method more sensitive than (simple) routine diagnostic most laboratories. results also group.
