SUMMARY
1. | Pathogenic fungi were isolated from clinical lesions as readily on actidione medium as on Sabouraud's agar. | ||||
2. | Cultures made on actidione medium were less frequently contaminated with saprophytic fungi than were cultures on Sabouraud's agar. | ||||
3. | Of 42 stock cultures of pathogenic fungi, all except 6 were shown to grow well on the actidione medium. | ||||
4. | Of 15 stock cultures of saprophytic fungi, the growth of 8 strains was considerably less on the actidione medium than on the Sabouraud medium, while six strains did not grow at all on the former. | ||||
5. | The actidione medium caused no change in the gross or microscopic characteristics of the cultures studied. | ||||
6. | The actidione medium may be useful in the isolation of pathogenic fungi from clinical lesions, and may aid in keeping stock cultures free from contamination with saprophytic fungi. |
