Abstract
SUMMARY: In the hypha of Paracoccidioides brasiliensis the succinic dehydrogenase activity is localized in the mesosomes, plasma membrane and mitochondria. Short permanganate fixation after incubation enhances the positive cyto-chemical reaction. The higher activity is localized in mesosomes and it is observed as high electron-dense zones and concentric ring-like patterns. The membrane shows a spotty reaction and the mitochondrion shows a positive zone in the intracristae space.
