An automated method for the silver metal staining of a biological specimen includes treating the biological specimen with a solution including non-gelling gelatin, a solution including a silver salt and a solution including a reducing agent. Non-gelling gelatin is soluble in cold water and the non-gelling gelatin solution can be formed and dispensed onto the biological specimen from liquid dispensers at room temperature. The method can be used in an automated process to detect spirochetes and other bacteria in tissue sections.
