The 3 most common agents are: - Fonsecaea pedrosoi-most common, tropical areas - Cladosporium carrioni-most important in dry areas, like austrialia, common cause of chromoblastomycosis, and is particularly prevalent in arid and semi-arid areas, most often in tropical and subtropical zones. - Phialophora verrucosa-2 nd most common, are known to be a cause of both chromoblastomycosis, and phaeohyphomycosis -Infection: saprobes located in soil and decaying vegetation. Enter by trauma world wide distribution especially in warmer climates like the tropics or the southern U.S. lesions take several years to develop. called dematiaceous fungi, because they have a black color in the mycelium cell wall (in culture and in tissue). In tissue fungi form sclerotic bodies brown pennies which are the reproductive forms dividing by fission. Orgination: chromoblastomycosis are septate, mold-like, branching, darkly pigmented which produce asexual fruits called conidia. -Identification and treatment: in culture by the shape and formation of the conidia on potato glucose agar and lactrimel agar.
