Pathogenicity of some Chrysosporium species isolated in France.

Abstract:

:In order to appreciate the pathogenicity of several geophilic Chrysosporium species (including Anixiopsis stercoraria, Chrysosporium keratinophilum, C. tropicum, C. pannorum, C. state Arthroderma curreyi, C. state of A. multifidum, and C. state of A. tuberculatum), the authors have realized two series of experimental infestations. Inoculation of these fungi on the back of guinea pigs produced rare erythematous scaling lesions which spontaneously disappeared 3-5 weeks later. No real hair invasion was observed. In white mice, eight weeks after intraperitoneal inoculation, granulomas with necrotic center were observed in the peritoneal tissue with C. keratinophilum, C. tropicum, C. state of A. curreyi and C. state A. tuberculatum. Conidia were often intact in necrotic centers and retrocultures were positive. With C. state of A. curreyi, spherical spores associated with rare budding cells were noted. The pathogenic role of these keratinophilic fungi is uncertain. However, their ability to remain viable for several weeks in skin and peritoneal tissue indicates that they could become pathogen in certain circumstances.
