title: Isolation of Sporothrix schenckii in the soil in Israel in relation to a new case in man.
abstract: A new case, the third in Israel, of subcutaneous sporotrichosis is presented. A pigmentary strain of Sporothrix schenckii was cultured from the unopened and necrotic nodules of the left hand and forearm of an 80-year-old male. Experimental inoculation of the isolated fungus into mice led to the dissemination of the organism in the liver, kidneys and lungs inoculated intraperitoneally, and the development of orchitis with abscess formation in those inoculated intratesticularly. In both groups of mice the causative agent was successfully recovered. Three months of treatment with oral potassium iodide led to the disappearance of the lesions. The source of contamination was found to be the soil adhering to fragments of wood. Two strains of a fungus, morphologically identical to the human S. schenckii, were isolated through the mouse procedure and agar-plating method from soil samples collected in the vicinity of the patient's residence. The soil isolates also proved to be pathogenic in animal inoculation. This is the first isolation of S. schenckii from soils in Israel. The possible relationships between the soil isolates and Ceratocystis stenoceras are discussed.
