Abstract: On the basis of epidemiologic survey we have identified that Tongyu county of Jilin provice is a region with high incidence of sporotrichosis.In order to isolalate the pathogenic fungus of sporotrichosis from natural environment,we collected the decayed reed from the bottom of the reed pile at the papermill located in the county,then cultured the sample of the reed and isolated the fungi found.The morphology of colony and fungus structure isolated were observed for the first and secondary colony.The immunological characteristics were studied by ABC-ELISA,and the pathogenicity of the isolates and histopathological changes were studied in experimental animals.The results verify that the fungi isolated from reed were Sporothrix schenckii.The conclusion of study shows there are parasitic Sporothrix schenckii in the putrid reed in the region with high incidence rate of sporotrichosis.
