New Bacterial Species Linked to Devastating Noma Disease
Researchers have identified a potential new culprit behind noma, a horrific and often fatal disease that destroys the faces of malnourished children.
Liverpool, UK – A team from the Liverpool School of Tropical Medicine has discovered a new species of Treponema bacteria in the mouths of children suffering from noma. This neglected tropical disease begins as a simple gum sore but rapidly progresses to destroy the tissues of the mouth and face.
The study, which analyzed samples from 19 infected children in Nigeria, revealed a stark imbalance in their oral bacteria. The bacterial community in noma patients showed fewer normal, healthy bacteria and a significant increase in other strains.
The new species, provisionally named Treponema A, was found in the majority of patient samples—a strong lead in the long-standing mystery of what causes the disease.
Understanding Noma
Noma primarily affects children living in extreme poverty who are already suffering from malnutrition. Without treatment, the disease is fatal in 90% of cases. While broad-spectrum antibiotics can stop its progression, the precise cause has remained unknown, hindering prevention efforts.
The Next Step: Proving the Link
The discovery is a major step forward, but it is not yet proof of causation. The research team is now expanding the study significantly.
- The team is collecting additional samples from both noma patients and healthy individuals across multiple countries.
- The goal is to determine whether Treponema A can colonize a noma wound or actively cause the disease.
Professor Adam Roberts, who leads the research, emphasized the need for caution. “Causality has not been established,” he stated. “We hope the larger study will provide the answers we need to ultimately prevent this terrible disease.”
