[Ecology of Sporothrix schenckii and of Ceratocystis stenoceras in Corsica and Alsace, French provinces free of sporotrichosis].
The study was conducted in 2 French Provinces free of sporotrichosis. Of 40 samples (soil, plant fragments, . . .) taken from Corsica, 59 isolations were obtained. All of these contained S. schenckii type of growth. Of 30 retained for further study, 14 were later identified as Ceratocystis stenoceras. All 14 needed pyrimidine as a growth factor. They developed well at 37 degrees and gave a yeast-like growth in shaken medium at 35 degrees and 25 degrees. One of the strains was pathogenic to mice. From 422 small mammals trapped in Alsace 37 isolations were made which morphologically were identified as S. schenckii. From these 31 were identified as C. stenoceras. Six isolations were considered as S. schenckii. The presence of nature of C. stenoceras and S. scheckii is discussed. Both fungi were isolated from various materials collected in tropical areas where sporotrichosis is endemic but also in such temperate areas as Corsica and Alsace where the mycosis is non-existent.
