Basic Fuchsin is a dye composed of rosaniline, magenta II, pararosaniline, and new fuschsine. The fluorescent dye has been used for Ziehl-Neelson staining in order to detect acid-fast bacilli. The dyes fluorescence has been useful in understanding microfissures, as it allows a clear delineation of surface level structure and constant background from the microscope. Basic Fuchsin staining includes tissue sections to visualize elastic fibers, and cardiac and skeletal muscle tissue. Reports show that Basic Fuchsin has the ability to stain tubercle Bacillus, bacterial flagella, and to compare Escherichia coli and Aerobacter aerogenes.
