The organisms in pathologic tissues of sporotrichosis were detected by ABC technique. Brown spores were found, some spores appeared to be round, or pearshaped,budding spores or asteriod hotlies were observed, and some spores were phagocytlzed by leukocytes and macrophages. The diameter of spores ranged from 2. spin to 10. 0um. The sensitivity of this method is 96. 2% and the specificity 100%. Examining one case takes about three hours. The method can be used for retrospective study, as well as rapid diagnosis of sporotrichosis.

Objective To investigate the effect of potassium iodide on the incidence of sporotrichosis, and provide the theoretical basis for the prevention of sporotrichosis. Methods Experimental mice were divided into 4 groups, group 1～3 were fed with water containing different doses of potassium iodide, and no potassium iodide was given to the control group. After two weeks, the fungi were inoculated intraperitoneally to all the mice. In the third to the eighth weeks, the mice were sacrificed every week in batches. The infection, pathological changes and mycological findings of the mice were observed. Results The incidence rate of experimental sporotrichosis was significantly decreased in the mice (P
