Abstract

It has been well known that Sporotrichum Schenckii is the causative microorganism of sporotrichosis infected through skin injury ands is present in soils, domestic and wild animals, corn, timber, plants and mines as a parasitic: or saprophytic sites.
Before understanding the relationship bet ween sporotrichosis and its sources of infection., the distribution of S. schenckii of each country should first be investigated not only from the epidemiological point of view but also for prevention of the disease. In this connection in countries where the disease has developed, many workers have already reported their own. flora of S. schenckii. However, the investigation of its flora in Korea has not been reported! yet.
For the purposes of determining the distri bution of S. schenckii in Korea, the author ha:. isolated S. schenckii from 120 soil sample~~ collected from various habitats in Kyungsang pook-do and Busan, and the following result: were obtained.
1. Sixty strains of S. schenckii were isolatedfrom 120 soil samples among which 55 were albino strains and 5 w ere black strains.
2. Morphological findings of fungal elements and growing patterns on Sabouraud agar were similar to that of pathogenic strains.
3. The optimum temperature for gra ~ ing was 30 C on Sabouraud agar media and albino strains grew the most quickly, feilo;-vcd by black strains and pathogenic strains in that order.
4. The albino strains did not charge_ to the black on potato and corn me~~l agar nleui~~.
5. The rate of isolations ~;-as 10;~;; is s~nr.y areas and 66.7 J, in shaded areas.
6. The rate of isolations by special hubacas was 86.7 o in stables and 40 to 7. i´~.~ in areas covered with organic materials.
7. The albino strains were dirt; ii~uted in whole areas examined, while the black strains could only be found in the soils underneath storage piles of timber, barley strays- and p:.ddy.
8. The rate of isolations accoding to month -was 74.1 o from October to November, 6i:.8 from Dzcember to January and 50% in March.
