[Stable solution of fuchsin--a new method for preparation of Ziehl-Neelsen staining].
The fuchsin salts currently available in Latin American market have shown some instability when in solution, according to the classic Ziehl-Neelsen method, resulting in a total precipitation of the salt. The authors indicate a new technique for the preparation of this solution, in order to minimize the action of interfering factors responsible for the precipitation, obtaining thus a greater solubility of the salt, as well as the solution stability. The method effectiveness is reinforced by the utilization of a smaller amount of the salt and the attainment of a larger storage period for the solution.
