How to Recognize Resistant Tuberculosis? (image) Institute of Tropical Medicine Antwerp Caption The fluorescent lines are living tuberculosis bacilli, on a background of cellular debris from human sputum. Scientists of the Antwerp Institute of Tropical Medicine gave a new application to a forgotten technique: Fluorescein diacetate staining, which only stains living tuberculosis bacilli (and not dead ones). This way they can see immediately after treatment if resistant bacilli survived. This simple technique can replace classical microscopy, now the standard procedure in developing countries, which cannot make this distinction.
