Why do low concentrations of alcohol inhibit Gram-negative bacteria more than Gram-positive bacteria?
Explain how the alcohol interacts with:
1) Gram-negative cell wall structures
2) Gram-positive cell wall structures
Diseases that involve biofilm-producing bacteria are of serious concern. They are not as easily treated compared with those involving free-floating (or planktonic) bacteria. Explain three reasons why biofilms can be more pathogenic.
