Among the strongest microbial predictors of frailty and mortality in the SUPERB cohort, even after adjusting for gene richness, were Enterocloster species, known opportunistic pathogens, and S. mutans, a facultative anaerobe found in the oral cavity. The abundance of Clostridium Q symbiosum was associated with frailty in the SUPERB cohort and with mortality both in SUPERB and in the Chinese elderly cohort, and has also been linked to unhealthy aging in previous studies.(([[https://www.news-medical.net/news/20260708/Study-links-gut-bacteria-diversity-to-frailty-in-seniors.aspx]])) (([[https://www.nature.com/articles/s41467-026-75176-5|2026: Gut microbiota associates with frailty in older women]]))
