Staining Apparent Nuclear Material in Bacillus Cereus, Neisseria Catarrhalis and Other Cocci

Abstract

The method of staining involves the principle of reduction and oxidation of some cell component. The reduction is a function of the mordant and the oxidation that of the stain. Three areas of the cells may be differentiated depending upon the condition of the mordant. The wall may remain unstained, while that of the cytoplasm stains a light red and structures within this a deep red. The latter structures only may be stained by proper adjustment of the mordant.
