Story summary

Researchers at Liverpool School of Tropical Medicine identified a previously undescribed bacterium, Treponema A, in most mouth samples from 19 Nigerian children with noma.
Noma kills about 90 % of untreated cases and leaves survivors with severe facial scarring and social stigma.
Researchers say a diagnostic test for Treponema A could enable antibiotic treatment, reduce reliance on broad-spectrum drugs that risk antimicrobial resistance, and prompt probiotic therapy and studies to confirm the findings.
