New Treponema A bacterium linked to noma could enable early tests and targeted treatment
Researchers studying noma patients in Nigeria identified a previously undescribed Treponema bacterium (Treponema A) in most samples, suggesting a possible causal or contributory role and raising the possibility of diagnostic tests at the gingivitis stage and targeted antibiotics to prevent progression. If confirmed, this could reduce mortality and lifelong disfigurement and lessen reliance on broad-spectrum antibiotics; a larger, multi-country study is planned to clarify Treponema A’s role.
