Immunofluorescence assays using monoclonal antiphosphotyrosine antibodies revealed an accumulation of phosphorylated fonsecae residues at the site of attachment of F. In this regard, it has been recently demonstrated that plant defensins specifically recognize fungal CMH and cause microbial killing Thevissen et al.

These extracellular molecules were recognized by sera from individuals with chromoblastomycosis Alviano et al. In general, the inhibitory activities of these four HIV peptidase inhibitors were comparable to those exerted by pepstatin A, a prototypal inhibitor of aspartyl peptidases.

For this reason, the extracellular proteolytic profile of mycelial forms of F. Facultative or heterotypic synonyms: Fonsecaea pedrosoi Brumpt Negroni The alternative use of small antimicrobial molecules, supposedly able to penetrate the melanin shield and bind CMH, could be a promising option to control fungal growth. However, as in our case, too extensively distributed lesions and deep infections were not suitable for excision.
