In 1922, Dorner published a method for staining endospores. Shaeffer and Fulton modified Dorner’s method in 1933 to make the process faster The endospore stain is a differential stain which selectively stains bacterial endospores. The main purpose of endospore staining is to differentiate bacterial spores from other vegetative cells and to differentiate spore formers from non-spore formers.
Principle of Endospore Staining
Bacterial endospores are metabolically inactive, highly resistant structures produced by some bacteria as a defensive strategy against unfavorable environmental conditions. The bacteria can remain in this suspended state until conditions become favorable and they can germinate and return to their vegetative state.
