Introduction. Combination of PCR and Elek testing to identify toxigenic corynebacteria has revealed organisms described as non-toxigenic toxin-gene bearing (NTTB) Corynebacterium diphtheriae or C. ulcerans (i.e. PCR tox positive; Elek negative). These organisms carry part or all of tox but are unable to express diphtheria toxin (DT) and present a challenge to clinical and public health case management. Gap analysis/Hypothesis.
