Endospore staining is a process of colouring endospores for their visualisation. Endospores are thick walled spores formed during unfavourable conditions like heat and desiccation. They are reproductive structures but moreover they are a means of perennation. They are found in the genus bacillus and clostridium mainly. It is stained by a dye called as malachite green.
A. A positive result indicates that the organism forms endospore during unfavourable condition. There are chances that the organism may belong to genus bacillus and clostridium.
B. Negative result indicates that the organism does not form endospore during unfavourable condition. The bacterial cell maybe having some other method to survive during unfavourable environment.
Please rate high.
