"Oral Bacteria Interaction Produces Compound Behind Bad Breath"
Originally Published 1 year ago — by Phys.org
A study published in mSystems reveals that the interaction between two common oral bacteria, Fusobacterium nucleatum and Streptococcus gordonii, leads to the production of a chemical compound, methyl mercaptan, which is a major cause of bad breath. The researchers found that S. gordonii prompts F. nucleatum to produce more methyl mercaptan by releasing a substance called ornithine, which activates F. nucleatum's methionine salvage pathway. Understanding this bacterial interaction could aid in developing treatments for bad breath and preventing associated periodontal disease.
