The human mouth contains a wide variety of bacteria. While some are beneficial, others can cause gum disease and infections. Researchers have found a way to target disease-causing bacteria. They selected an antibiotic that ordinarily targets a wide range of bacteria and attached the drug to a protein that binds with the disease-causing Porphyromonas gingivalis bacterium. What would be the greatest widespread medical benefit of this technology?

increased knowledge of gum disease

eradication of Porphyromonas gingivalis bacteria

the ability to identify proteins that bind with bacteria

the ability to fight infection without the loss of helpful bacteria
