title: Microsporidium: modified technique for light microscopic diagnosis.
abstract: Microsporiodosis caused by Enterocytozoon bieneusi is one of the opportunistic infections in HIV positive patients with chronic diarrhea. The organism is difficult to diagnose because of its small size, previously the diagnosis of this infection relied on identification of the organism under electron microscope. Until recently, the spores of this organism in stool specimens could be seen under light microscope by using various staining techniques. In this study, the modified trichrome staining technique was used to identify microsporidia spores with characteristic red belt-like stripes. Less time and less reagent are required by this modified technique than the conventional method.
