Origin of diphtheriaModern Latin from French diphthérie (so named (1855) by A. Trousseau (1801-67), French physician, replacing earlier diphthérite, first used (1821) by P. 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
An example of diphtheria is a condition you get when exposed to bacteria that makes it hard for you to swallow or breath.

- The vexed question of the diagnosis of diphtheria is now a thing of the past.
- In the 1920s, we got a vaccine for diphtheria, pertussis, tuberculosis, and tetanus.
- 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 case of the tetanus and diphtheria bacilli, the production of soluble toxins can be readily demonstrated by filtering a culture in bouillon germ-free by means of a porcelain filter, and then injecting some of the filtrate into an animal.
- 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.
