Abstract: Objective To study the distribution of Sporothrix in natural environment in Jilin province. Methods Specimens of decayed reed, corn stalks, rotten wood and soil from areas of high incidence rate of sporotricosis (Tongyu county and Nongan county) and low incidence rate (Tumen county) were randomly collected, cultured and subcultured for sporothrix, and the isolates were identified. Results 21 strains of Sporothrix schenckii were isolated and identified. It is the first report that Sporothrix is isolated from corn stalks, rotten wood and soil in our country and is the first report in the world that Sporothrix is isolated from corn stalks. Conclusion The results of study show that there are parasitic Sporothrix schenckii in the reed, corn stalks, rotten wood and soil in the region with high incidence rate of sporotrichosis, and parasitic Sporothrix schenckii in the reed and rotten wood have also been found in the region with low incidence rate. The finding of biological distribution of Sporothrix in the province is of great significance for the prevention and treatment of sporothrichosis.
