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.
Origin of diphtheriaNew Latin diphthēria from French diphthérie from Greek diphtherā piece of hide, leather ; see letter .
- diph′the·rit′ic diph·ther′ic diph·the′ri·al
(countable and uncountable, plural diphtherias)
From French diphthérie, coined 1857 by Pierre Bretonneau; from Ancient Greek διφθέρα (diphthera, “prepared hide, leather”), for the tough membrane that forms in the throat. Bretonneau earlier used diphthérite, from which diphtheritis.
- 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 other cases such changes cannot be detected, and the only evidence of their occurrence may be the associated symptoms. The very important work of Ehrlich on diphtheria toxin shows that in the molecule of toxin there are at least two chief atom groups - one, the " haptophorous," by which the toxin molecule is attached to the cell protoplasm; and the other the " toxophorous," which has a ferment-like action on the living molecule, producing a disturbance which results in the toxic symptoms. On this theory, susceptibility to a toxin will imply both a chemical affinity of certain tissues for the toxin molecule and also sensitiveness to its actions, and, furthermore, non-susceptibility may result from the absence of either of these two properties.
- 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.
