Staining Mycobacterium Lepre with Carbolfuchsin: Properties of solution prepared with different samples of Basic Fuchsin.
J Pak Assoc Derma Jan ;8(3):21-5.

Acid fast staining of mycobacterium leprae in the form of beadings is obtained by means of a carbolfuchsin solution prepared from pararosaniline or from certain kinds of basic fuchsin. After such acid fast stains. The intensity of the bacilli`s colouring was rather poor and unstable, so that some bacilli lost their acid fast stain. The carbolfuchsin stain using the basic fuchsin with low absorption maximum shows beaded staining bacilli in contrast to roded staining bacilli with high absorbance basic fuchsin.
