In this study, the diagnostic yield of saline and iodine preparation of fresh faecal samples for the diagnosis of intestinal parasitic infections was compared to that of trichrome staining. 400 faecal samples were examined both in saline and iodine preparation and in trichrome-stained smears prepared according to the method recommended by WHO in oil immersion. Of the 400 specimens, 215 were positive for parasitic infections, of which 81 were diagnosed exclusively on trichrome-stained samples. Because of its better diagnostic yield, trichrome staining technique should be included in routine faecal examinations.
