Ziehl-Neelsen (ZN) stain is used worldwide as a standard method to detect AFB, but it has less sensitivity relative to fluorescent stain as it takes more time to scan at least 300 fields and often misses the paucibacillary tuberculosis.
The green fluorescent stain (SYTO 9, with excitation/emission maxima of about 480/500 nm) colors healthy bacteria that have intact membranes, thus staining live cells; and the red dye (propidium iodide with excitation/emission maxima of about 490/635 nm) colors bacteria with damaged membranes, by displacing the green dye, thus staining dead cells.
