TheOnygenales are anorder of fungi in the classEurotiomycetes and divisionAscomycota. The order's last common ancestor is estimated to have lived 150 million years ago.[1]
Onygenales can consume and break downkeratin, the main component of the outer layer of skin.[2] They are primarily found on animals, droppings, and areas frequented by animals. Many aredimorphic, and can change from mold to yeast form depending on their environment.[1]
Many onygenalean fungi arepathogens.[1] One species,Trichophyton rubrum, is the primary cause ofathlete's foot. This order also includes theCoccidioides implicated inValley fever. The Onygenales are important as emerging human pathogens because of the rising rates ofimmunosuppression due to live-organ transplant, HIV/AIDS, andautoimmune disorders such aslupus erythematosus.[3][page needed]
