Abstract
The present invention provides a method and apparatus for microscopic examination of samples containing bacteria in low numbers and which require precise staining procedures for visualization and counting. A slide has a filter assembly through which the bacterial suspension is filtered onto a filter membrane. A chamber adjacent to said filter, by sliding, delivers to the filter surface with simultaneous mixing, an optimum amount of bacterial dye at the proper concentration. The upper portion of the sliding chamber then fits over the filter membrane to form an incubation chamber. After incubation, the bacteria so stained are easily washed and conveniently further prepared for microscopic inspection. By use of this method and apparatus, all of the complex steps of the fluorescent antibody technique can be simply performed.
