The bacteria that you would not use a Gram stain on are Escherichia coli, Pseudomonas spp. and Clostridium spp, and Neisseria meningitidis.
<h3>
What are Gram stain negative bacteria?</h3>
Gram-negative bacteria have cell walls with thin layers of peptidoglycan and high lipid content.
This causes them to appear red to pink under a Gram stain.
<h3>Examples of Gram - negative bacteria</h3>
Gram-negative bacteria include:
- Pseudomonas,
- Klebsiella,
- Proteus,
- Salmonella,
- Providencia,
- Escherichia,
- Morganella,
- Aeromonas
- Citrobacter
- Neisseria meningitides
Thus, the bacteria that you would not use a Gram stain on are Escherichia coli, Pseudomonas spp. and Clostridium spp, and Neisseria meningitidis.
