THIS PAPER reports the effect of roentgen rays on Microsporum audouini, under experimental conditions approximating those presented in a previous study on Microsporum canis.1 The pertinent literature was cited in the latter publication.
MATERIALS AND METHODS
Two freshly isolated strains (JC and HM) were used. Six subcultures were prepared of each strain, two of which were irradiated on the day of inoculation; two seven days after inoculation, and two remained untreated to serve as controls. The irradiation was given through the glass wall of the medium container (½ oz. [15 cc.] perfume bottles), the filtration value of which was not known. Following are the technical data: Bracke-Seib Dermatron; two-valve tube rectification; Eureka tube type 13-; 85 kv.; 5 ma.; 25 cm. distance; 3 minutes 25 seconds; 340 r unfiltered. Three successive transplants from the irradiated colonies and their controls were prepared at intervals of three weeks. The
