Fifth meeting of the ISHAM working groups on Black Yeasts and Chromoblastomycosis

To assess population diversities among 108 strains of fungi in the genus Fonsecaea that had been identified down to species level, we applied sequenced the internal transcribed spacer regions and the partial cell division cycle, Elongation factor and β-tubulin genes. Many species of the genus Fonsecaea cause human chromoblastomycosis. Strains originated from a global sampling of clinical and environmental sources including samples from the several regions in Brazil where included in this study. According the preliminary results Fonsecaea isolates clustered in 05 groups corresponding with F. pedrosoi, F. monophora, and F. nubica. We observed two groups substantial geographic structuring which F. pedrosoi was found nearly predominately in North regions and the second group including F. monophora and F.pedrosoi were distributed all regions studied.
