It is possible to use Malachite green dye for differential spore staining in bacteriological samples of human origin, Dye is used in a hot staining method to stain specifically spores. Counterstain with a red dye for better visualization. The dye has a constant dye content and a reliable high quality and thus, is registered and certified as IVD CE product, one of the major precondition for a reproducible diagnostic staining.
