Bacteria have three major methods of resisting antibiotics. They may lack (or modify) the feature that the antibiotic targets, so that the drug has little or no effect. The may have an enzyme that helps them break down and inactivate the antibiotic. They may have efflux pumps that remove the drug from the cell. Which method of resistance are Gram-negatives particularly famous for? Group of answer choices target modification enzymatic breakdown horizontal transfer efflux pumps
