Comparative electrophoresis, isoelectric focusing and numerical taxonomy of some isolates ofFonsecaea pedrosoiand allied fungi

Abstract
The proteins in broken-cell extracts from 8 isolates of F. pedrosoi, the principal agent of chromomycosis, were studied and compared by electrophoresis and isoelectric focusing. A type pattern was established with 16 fractions ranging in MW between 7600-78500 daltons and 16 fractions varying in isoelectric point between 4.95 and 7.90. A genetic distance of 0.1 found by numerical study applied to both analyses reveal a considerable similarity among the isolates studied. This resemblance was observed between F. pedrosoi and other related dematiaceous fungi.
