Bacteriologic Features of Diphtheroids.
—The first attempt to establish an etiologic relation between a diphtheroid and a disease of the eye dates back to 1879, when Italian investigators1 isolated Corynebacterium xerose during the course of an institutional epidemic of xerophthalmia. Later, in 1883, German workers demonstrated the presence of diphtheroids on the conjuctiva of patients with a nutritional deficiency. However, it was soon realized that these bacteria are usually present on normal and inflamed conjunctivas, as well as on other normal and diseased surfaces of the body. It is of interest to note that in a recent review of the subject, published by the British Medical Research Council, the statement was made2:It is very doubtful if C. xerose is even now sufficiently well characterized to deserve a specific rank. So authors present a picture formed from composite conceptions of various workers.Likewise, the report of
