The Gram Stain and Differential Staining

Ribonucleates and the Gram stain.

Salton (J. Gen. Microbiol. 30:223, 1963) summarized the evidence which demonstrates that the gram-positive cell is able to retain the crystal violet after iodine treatment because of the characteristic nature of its cell wall. This evidence is highly convincing, yet it does not explain the experiments of Henry and Stacy (Proc. Roy. Soc. London Ser. B 133:391, 1946) or of Bartholomew and Umbreit...

The Gram stain.

Mechanism of gram stain reversal.

This paper deals with an investigation of the effect of these reactions on bacteria. Not only the common staining behavior but also certain other similarities (Fischer et al., 1949; Fischer, 1951) between intact wool and gram negative bacteria, medium degraded wool and gram variable bacteria, as well as between highly degraded wool and gram positive bacteria suggested that reversal of gram stai...

Combined silver Perls's stain for differential staining of ringed sideroblasts and marrow iron.

During a study of nucleolar organiser regions, a modified silver stain was found to be a sensitive marker for the iron in ringed sideroblasts, more so than Perls's stain when the marrow iron stores were low. To enhance the usefulness of the silver stain, a combined silver Perls method was developed. This stains the ringed sideroblast iron black and haemosiderin blue, thus rendering the detectio...
