Representative results for histopathological sections of brain (A and B) and kidney (C and D) tissues stained with Grocott-Gomori's methenamine silver nitrate from mice infected with R. oryzae 4570. Control mice (A and C) show typical infection foci in both tissues. Posaconazole, given for three consecutive days at 30 mg/kg/day, was not effective in the brain (B), while it reduced the hyphal growth in the kidney (D). Magnification, ×130.
