Development of Natural Culture Media for Rapid Induction ofFonsecaea pedrosoiSclerotic Cells In Vitro

Abstract
Fonsecaea pedrosoi is the main agent of chromoblastomycosis, a skin disease presenting verrucous lesions, in which round, thick-walled sclerotic cells are found. In vitro induction of sclerotic cells is time-consuming (20 to 45 days) and temperature dependent. We present two new natural media that reduce the sclerotic-cell induction time to only 2 days.
