title: Growth temperatures of isolates of Sporothrix schenckii from disseminated and fixed cutaneous lesions of sporotrichosis.
abstract: In 1979 Kwon Chung described two varieties of Sporothrix schenckii based on the thermotolerance of isolates from fixed cutaneous (35 degrees C) and that of disseminated cutaneous forms (37 degrees C) of sporotrichosis. Since we had not noted such a difference previously in a study of 100 cases of this disease (55% localized and 45% disseminated) wherein all the isolates grew at 37 degrees C, we decided to repeat this work. Our results differ from those reported by Kwon Chung, since the isolates of both the fixed and disseminated forms of sporotrichosis grew at 37 and 38 degrees C, even when we used inocula of 30 conidia (20-50) which according to Kwon Chung were needed to observe this difference.
