Study of the conidial development and cleistothecium-like structure of some strains of Fonsecaea pedrosoi

Comparison with other close dematiaeae

The reproduction of twenty-seven strains of Fonsecaea pedrosoi was studied. The denticulate type (asexual reproduction) showed three morphological variations: medium-size, long and sessile forms. These forms can be used to characterize the different strains isolated especially for epidemiological purposes.

Only one strain (MR 1335) isolated from a chromomycosis case in Martinique showed a cleistothecium-like structure. This formation was compared to that observed in Phialophora verrucosa, another agent of chromomycosis, and to the cleistothecium of Dictyotrichiella mansonii, the perfect state of Wangiella mansonii which is a saprophyte fungus.
