The histochemical stain results for acid-fast bacilli (Ziehl-Neelsen) and fungi (Gomori methenamine-silver
stain) were likewise negative.
Tissues were sectioned in 5-[micro]n slices and were subsequently stained with hematoxylin and eosin, Gram's, Ziehl-Neelsen, periodic acid--Schiff, and Grocott methenamine-silver
Ziehl-Neelsen and Brown and Brenn stains were again non-contributory, but a Grocott-Gomori methenamine-silver
Stains for acid-fast bacilli with Grocott-Gomori methenamine-silver
nitrate were negative.
4) The organisms are readily apparent with the use of special histochemical stains, such as Gridley fungus stain, periodic acid-Schiff (with or without diastase), and Gomori methenamine-silver
stain (Figure 3).
and acid-fast stains were negative for fungal and mycobacterial organisms, respectively.
Microcrystalline cellulose, on the other hand, retains the staining properties of native wood cellulose and can be highlighted by periodic acid-Schiff (with or without diastase), Congo-red (without apple-green birefringence), and Gomori methenamine-silver
Two histologic stains--periodic acid-Schiff (PAS) and Grocott-Gomori methenamine-silver
stains--were used to visualize the tissue and the fungal pathogen.
They stained positively with periodic acid-Schiff (Figure 4) and Grocott-Gomori methenamine-silver
stain (Figure 5).
Four-micrometer cross sections of tissue were stained with hematoxylineosin and Gomori methenamine-silver
Fite and Gomori methenamine-silver
stains were negative for acid-fast and fungal organisms.
Special stains, including Fite, Ziehl-Neelsen, and Gomori methenamine-silver
stains, were negative.
