(two) pathogenesis This disease by Pei, close, verrucous, cause dermatitis fungal and Cladosporium, domestic to Cladosporium carrionii was most common, followed by Fonsecaea pedrosoi strain, Fonsecaea compacta, jeanselmei Phialophora, recently discovered Exophiala spinifera and dematiaceous hyphomycetes caused by mildew. Dematiaceous fungi as opportunistic pathogens, which has more than 30 genera and 50 species, the phases were separated and rounded hyphae brown, brown fungal cells in tissue or pus, diameter of 6 ~ 12 m, not bud, is widely distributed in nature, many parasites in the soil and wet rot the rotten straw wood, when the body immunity, spores and hyphae in the air through the lungs, human skin wound infection or other way, and can be spread by the blood circulation to the body, even the involvement of the brain tissue and other organs.
