MALACHITE GREEN FOR MICROSCOPY
Malachite green has classically been used by the light microscopist for the demonstration of fungi and bacterial spores
Malachite green has classically been used by the light microscopist for the demonstration of fungi and bacterial spores. It is a weakly basic diaminotri- phenylmethane dye with useful indicator properties at both very high and very low pH Malachite Green is used for bacterial spore staining by Schaeffer and Fulton`s method. It can also be used in place of methyl green in the Pappenheim stain, when combined with the Gram stain.
It is used as a biological stain for microscopic analysis of cell biology and tissue samples. In the Gimenez staining method, basic fuchsin stains bacteria red or magenta, and malachite green is used as a blue-green counterstain. ... Malachite green is in a class of molecules called fluorophores.
MALACHITE GREEN helps for TREATMENT of DISEASES in FISH
Saprolegnia parasitica is a rapidly spreading and fatal fungal parasite affecting both fish and fish eggs. It is conventionally treated with MALACHITE GREEN (diamino-triphenylmethane), but though this treatment is highly effective, the use of malachite green carries with it a number of potential problems: the compound has been suggested as a possible carcinogen and teratogen, though these effects are as yet unproven; being a strong dye, it tends to discolour water, and can under certain conditions cause staining of fish which have been treated; it has a relatively long withholding period, so that significant residues can be present in treated fish when they are harvested and sold for consumption.
