Symptoms of Diphtheria The signs of diphtheria appear in a short period of time within three to five days after the infection has occurred. Some people do not feel any symptoms, while others do feel slight symptoms of a common most common and visible symptom of diphtheria is gray, thick covering on the tonsils and throat. Fifty-two strains of diphtheria bacilli and diphtheroids were classified. Thirty-five of the strains came from the throat (1 carrier), 16 from the nose (2 carriers) and one strain from the eye. Differentiation into groups was attempted by different criteria but only five methods of study were found to be of any value, viz.: (1) morphology; (2) growth on sodium oleinate agar; (3) fermentation.

The incubation period of diphtheria is 2–5 days (range, 1–10 days). Disease can involve almost any mucous membrane. For clinical purposes, it is convenient to classify diphtheria into a number of manifestations, depending on the anatomic site of disease. Anterior Nasal Diphtheria. The onset of anterior nasal diphtheria is indistinguishable.

Swabs from children diagnosed as suffering from, or suspected of, diphtheria were seeded on to coagulated serum and on to a heated-blood-tellurite medium. The results of the comparative tests agreed with those previously recorded by other workers elsewhere, in that the tellurite gave a greater proportion of positives than the serum, but that the most satisfactory results were obtained when both Author: M.

In severe cases, a grey or white patch develops in the : Corynebacterium diphtheriae (spread by.

There is a need for continued surveillance for diphtheria in this part of the country and review. When Edwin Klebs identified the diphtheria bacillus and Friederich Loeffler later isolated it intheir discoveries offered a way to diagnose diphtheria more precisely.
Yet many American doctors were skeptical of this European breakthrough and their doubt curtailed universal use of bacteriological diagnosis. Bull Calcutta Sch Trop Med.

Diphtheria, acute infectious disease caused by the bacillus Corynebacterium diphtheriae and characterized by a primary lesion, usually in the upper respiratory tract, and more generalized symptoms resulting from the spread of the bacterial toxin throughout the body.
