Antibiotic Combinations Tackle Resistance Using combinations of certain antimicrobial compounds can favor the growth of non-resistant strains of bacteria at the expense of resistant ones. The surprising finding may provide a general strategy to help eradicate strains of bacteria that are resistant to antibiotic therapy.  |
