Figure 1a. B dermatitidis. (a) Photomicrograph (original magnification, x100; hematoxylin-eosin stain) shows a typical round B dermatitidis yeast cell (arrow) with a thick double refractile cell wall and surrounded by granulomatous tissue. (b) Photomicrograph (original magnification, x100; Gomori methenamine silver stain) shows reproducing B dermatitidis cells, which are characterized by broad-based budding and large daughter cells that are nearly as large as the mother cell before separation.
