A Dermatitis caused by Larvae of Ancylostoma caninum.

While conducting experimental studies on creeping eruption, a disease caused by infective larvae of one of the hookworms,Ancylostoma braziliense, infesting the dog and the cat, we produced a somewhat similar dermatitis, using larvae of another hookworm,Ancylostoma caninum, that infests the dog and the cat. The observations which have been made on the latter infection indicate strongly that it is a clinical entity as well as an experimental one. A skin disease caused by larvae ofAncylostoma caninumis naturally of much interest in itself. Since it is in some respects similar to, and probably occurs occasionally in, a mixed infection with creeping eruption, it has an added importance in the diagnosis of, and the treatment for, the latter disease. The present paper is a brief discussion of some studies on the caninum dermatitis.1 EARLY EXPERIMENTAL STUDIES ON CREEPING ERUPTION With Kirby-Smith, we2were able to show
