A B C D E  Divide bacteria into two groups based on cell wall structure (thick vs. thin).
A B C D E  Look for the presence of a capsule.
A B C D E  Stain microbes a bright color to make it easier to see them in bright field microscopy.

A The Schaeffer-Fulton Endospore stain B The Ziehl-Neelsen Acid-fast stain C The Gram stain D Simple stain with a basic dye E A Negative stain such as India ink or Congo red.

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
