Demonstration of Cultures and Photographs of Some Dermophytes. By Dr. Howard Fox.
Cultures of thirty species of Microsporon, Trichophyton, Achorion and Epidermophyton in 250 cc. flasks on Sabouraud's isolation medium were shown. Glucose had been used in place of the now unobtainable maltose. Hanging drop cultures were also demonstrated under the microscope. Photographs were then shown of direct microscopic preparations, cultures on solid mediums, hanging drop preparations and a few clinical cases. About three fourths of the cultures on solid mediums (Sabouraud's isolation agar) had been made on petri or stender dishes. This obviated the somewhat troublesome procedure of breaking the flask to obtain a photograph. The technician had succeeded in cultivating these organisms on petri dishes with a small incidence of contamination. This was contrary to the experience of Sabouraud who considered petri dishes unsatisfactory. In Dr. Fox's earlier work, photographs had been made through the flask, but were
