I want to know the answer to the following question:
What can different structure of the cell walls of bacteria effect?
All the background I'm provided with is that "These differences in structure can produce differences in antibiotic susceptibility; for instance, vancomycin can kill only gram-positive bacteria and is ineffective against gram-negative pathogens, such as Haemophilus influenzae or Pseudomonas aeruginosa.". Is that enough to answer the question?
