in Zn we use 3% decolorizer, while in modified 1% h2so4 is used, modified is used for paracite like Cryptosporidium, cyclosporidium and bacterias like nocaddia and actinomyces. also in modified heating isn't done.

The main difference between ZN (Ziehl-Neelsen) stain and modified ZN stain is the addition of a decolorizing agent such as acid-alcohol in the modified version. This allows for better differentiation between acid-fast bacteria (such as Mycobacterium spp.) and non-acid-fast bacteria in samples. The modified ZN stain is considered more sensitive and specific compared to the traditional ZN stain.
