Studies of Ringworm. Part IV. Incidence of Trichophyton Gypseum in India *Read at the Indian Science Congress held in January 1947 at Delhi.

. Trichophyton gypseuni Bodin 1902 or any ot its many variants has not been recorded in India as yet. It is the cause of the small-spored ectothrix trichophytosis in man. Being of animal origin it produces more inflammatory reactions than other ringworm fungi. In children.?It causes the ringworm of the scalp (Tinea capitis) often producing the condition called the 1 kerion ' in which the affected patches are acutely inflamed and raised to a b?ggy swelling; the hair follicles are gaping wide and contain pus, the hairs become loose and easily come out. In adults.?Besides causing ringworm of the scalp it affects the secondary sex hairs causing sycosis barbEe (Tinea) in the beard region and pustular folliculitis in the pubic region. It also affects the lanugo hair, the glabrous skin and the nails. Similar inflammatory reaction takes place when it affects the hair follicles of the beard and pubic regions and also the lanugo hairs. The affections of the glabrous skin and the nails resemble ordinary ringworm lesions.
