A study links MS to harmful shifts in mouth bacteria and reduced nerve-protecting compounds in saliva.
A University of Iowa study links multiple sclerosis (MS) to significant changes in the oral microbiome, finding MS patients have lower levels of beneficial bacteria like Streptococcus and Actinomyces, higher levels of harmful species such as Fusobacterium nucleatum and Porphyromonas gingivalis, and reduced hypotaurine—a compound tied to nerve health.
The research, based on saliva samples from 50 MS patients and 50 healthy controls, reveals disrupted microbial networks and suggests oral dysbiosis may contribute to inflammation and immune issues in MS.
While the exact role remains unclear, the findings open potential for future saliva-based diagnostics and therapies.
