Chrysosporium is a genus of hyaline hyphomycetes fungi in the family Onygenaceae .[2]
Chrysosporium colonies are moderately fast-growing, flat, white to tan to beige in color; they often have a powdery or granular surface texture. Hyaline , one-celled (ameroconidia ) are produced directly on vegetative hyphae by non-specialized conidiogenous cells. Conidia are typically pyriform to clavate with truncate bases (6 to 7 by 3.5 to 4 um ) and are formed either intercalary (arthroconidia ), laterally (often on pedicels ), or terminally.
Clinical significance [ edit ]
Species of Chrysosporium are occasionally isolated from skin and nail scrapings, especially from feet, but, because they are common soil saprotrophs , they are usually considered as contaminants. There are about 22 species of Chrysosporium, several are keratinophilic with some also being thermotolerant , and cultures may closely resemble some dermatophytes , especially Trichophyton mentagrophytes , and some strains may also resemble cultures of Histoplasma and Blastomyces .[citation needed ]
Chrysosporium has been identified as an emerging infectious disease , first in Canada affecting reptiles at around 1995.[3] It infected eastern massasauga rattlesnakes (Sistrurus catenatus catenatus ).[4] By 2011, it had affected northern copperheads (Agkistrodon contortrix mokasen ), timber rattlesnakes , black rat snakes , black racer snakes and eastern garter snakes in New Jersey.[3]
