Bretonneau (1778-1862), French physician) from Classical Greek diphthera, leather from dephein, to tan hides from Indo-European base an unverified form deph-, to knead, stamp from source Armenian top'el, to strike

- The vexed question of the diagnosis of diphtheria is now a thing of the past.
- Thus, to mention examples, diphtheria toxin produces inflammatory oedema which may be followed by necrosis; dead tubercle bacilli give rise to a tubercle-like nodule, &c. Furthermore, a bacillus may give rise to more than one toxic body, either as stages in one process of change or as distinct products.
- In the 1920s, we got a vaccine for diphtheria, pertussis, tuberculosis, and tetanus.
- Quite irrespective of the nature of the anatomical lesion, the finding of the diphtheria bacillus on the part affected and the inoculability of this upon a suitable fresh soil are the sole means by which the diagnosis can be made certain.
- In 1870 Pasteur had proved that a disease of silkworms was due to an organism of the nature of a bacterium; and in 1871 Oertel showed that a Micrococcus already known to exist in diphtheria is intimately concerned in producing that disease.
