Abstract
A fixative-stain system, which gives superior preservation of nuclear detail, is free from toxic mercury compounds, and which is simple and easy to use, includes a zinc salt and a cobalt salt, in combination, as a fixative, and at least one of Chlorazol Black E, Fast Green FCF and May-Grunwald stains, and preferably the three in admixture, as a staining composition. The fixative may also be used alone. The present fixative-stain system is suitable for fixing and staining all types of parasites such as enteric and other parasites which infect animals and humans.
