Abstract

The bacterial attachment sites of independently isolated Corynebacterium diphtheriae strains C7s and (belfanti)1030 lysogenic for corynebacteriophages beta tox+, omega tox+, and gamma tox- were determined by Southern blot analysis. Both corynebacterial strains contained two distinct bacterial attachment sites (attB1 and attB2). We found that infection by any of the three closely related corynebacteriophages may give rise to single, double, and triple lysogens. In the case of toxigenic C. diphtheriae strains C7s(beta tox+) and C7s(omega tox+), the final yields of diphtheria toxin produced under optimal conditions were equivalent and varied by one-, two-, or threefold depending upon the number of integrated prophage.
