The role of extracellular DNA in Neisseria biofilms.

Extracellular DNA is essential for the formation, structure, and stability of Neisseria biofilms, with eDNA contributing to biofilm development in pathogenic and commensal species.

• Why it matters: Understanding biofilm formation in Neisseria is important because biofilms enable bacterial persistence and immune evasion, impacting both pathogenic infections and commensal colonization.
• What they did: The review discusses the sources and roles of eDNA in Neisseria biofilms, emphasizing its contribution to biofilm formation and stability across pathogenic and commensal species, with a call for more research on nonpathogenic Neisseria.
• The result: Highlighting the significance of eDNA in biofilm integrity may guide future studies on Neisseria colonization and pathogenicity, especially in understudied commensal species.
