Diphtheria toxin (Corynebacterium diphtheriae)
1997Abstract Diphtheria toxin is the primary virulence factor of toxigenic C. diphtheriae the etiologic agent of clinical diphtheria (Pappenheimer 1977). The structural gene for diphtheria toxin, tox, is carried by a closely related family of corynebacteriophages of which the β-phage has been the best studied (Buck et al.

Iron and Diphtheria Toxin Production
1975The extreme sensitivity of diphtheria toxin production to the iron concentration of the medium was clearly shown by Pappenheimer and Johnson [1]. Iron level of the medium, therefore, has to be carefully controlled whether diphtheria toxin is produced using a surface or a submerged culture.

Nature, 1968
ULTRACENTRIFUGAL studies have shown that purified diphtheria toxin is a single protein with a molecular weight of 64,500 and an S20, w of 4.2 (ref. 1). In this communication, I report experiments with a sample of toxin that contains the 4.2 S molecule, and an unusual species with a higher sedimentation constant.

The Diphtheria Toxin Structural Gene
1985While there was considerable indirect evidence that toxinogenesis in Corynebacterium diphtheria was related to lysogeny (FREEMAN 1951; FREEMAN AND MORSE 1952; GROMAN 1953 a, b, 1955; GROMAN and EATON 1955; HOLMES and BARKSDALE 1969), it was not until the report of UCHIDA et al.

Potent Diphtheria Toxin within the Cells of C. diphtheriae
Nature, 1954ALL the exotoxins except diphtheria toxin have been demonstrated within the bacterial cells in a very early stage of culture. So far as diphtheria toxin is concerned, it has been postulated, but never proved, that the exotoxin is formed within the cell.
