Explanation / Answer
The Schaeffer-Fulton Endospore stain used to identify bacillus or clostridum species such as the caustive agensts of anthrax , botuluism, tetanus and gangrene .
the gram,strain ; divide bacteria intpo two groups based on cell wall structure
the zeilhl-neelsen acid fast stain - identify the bacteria waxy cell walls such as mycobacterium tuberculosis.
simple stain - stain microbes a brighter colour to make it easier to see them in bright feild microscopy
A Negative stain such as India ink or Congo red - looking for the presence of capsule
