What Is Already Known About This Topic?:
This is the first report of Corynebacterium belfantii (C. belfantii) in Fujian; genomic characterization confirms misidentification by routine methods and reveals regional phylogenetic characteristics.
What Is Added By This Report?:
This report adds the first local occurrence evidence, new genomic sequences, a distinct phylogenetic sub-branch, and a reinforced surveillance strategy for Fujian Province.
What Are The Implications For Public Health Practice?:
It emphasizes that laboratories should adopt molecular methods to accurately distinguish C. belfantii, strengthen surveillance of non-toxigenic strains, update MALDI-TOF databases, and monitor virulence and resistance genes despite the absence of diphtheria toxin.
