Diphtheria due to non-toxigenic Corynebacterium diphtheriae: a report of two cases.
Diseases due to non-toxigenic strains of Corynebacterium diphtheriae are being increasingly reported. These diseases have been found to occur in vaccinated individuals. We report two cases of diphtheria with myocarditis and polyneuritis caused by non-toxigenic strains of C. diphtheriae. The virulence factors of this organism and the pitfalls in diagnosis have also been discussed.
