Apparently which bacteria is more resistant to antibiotics?
Correct answer: B. Gram-negative bacteria
- A. Gram-positive bacteria
- B. Gram-negative bacteria
- C. Both Gram-negative and positive bacteria
- D. None of these options are correct
Explanation
Gram-negative bacteria have an outer layer (membrane) that protects them from their environment. These bacteria can use this membrane to selectively keep antibiotic drugs from entering. Germs get rid of antibiotics using pumps in their cell walls to remove antibiotic drugs that enter the cell. Gram-positive bacteria, those species with peptidoglycan outer layers, are easier to kill - their thick peptidoglycan layer absorbs antibiotics and cleaning products easily.
