Fonsecaea pedrosoi is a fungal species in the family Herpotrichiellaceaeand the major causative agent of chromoblastomycosis. Syk kinase signalling couples to the Nlrp3 inflammasome for anti-fungal host defence. The age and fomsecae distribution can differ depending on the region. In Korea, however, the infection occurred more often on the upper extremity rather than the lower extremity.

Characterization of cerebrosides from the thermally dimorphic mycopathogen Histoplasma capsulatum: Indeed, differently from what is shown in macrophages, F. Cells were washed, incubated with medium, and visualized by fluorescence microscopy. The above data confirmed previous studies revealing that fungal CMH and its biosynthetic pathway are potential targets for the development of new antifungal drugs Thevissen et al.

Interestingly, this structurally different CMH was also recognized in enzyme-linked immunosorbent assays by the mAb produced against the conserved structure. Aspartic proteases of Plasmodium falciparum and other parasitic protozoa as drug targets.

Conversely, conidia cultivated in Kauffman complex medium secreted a distinct peptidase whose activity was restrained by some metallopeptidase inhibitors, such as ethylene glycol tetraacetic acid and 1,phenanthroline Palmeira et al. Fonsecaea pedrosoi Brumpt Negroni.

Moreover, the response to oral antimycotic drugs is limited Minotto et al. Fonsecaea pedrosoi -induced Thcell differentiation in mice is fostered by dectin-2 and suppressed by mincle recognition.

Fonsecaea is a genus of ascomycetous fungi affiliated with the family Herpotrichiellaceae. Other fungal pathogens presenting a similar distribution of CMH at their surface had their differentiation process inhibited by the anti-CMH antibody, confirming an association between CMH expression and fungal growth Rodrigues et al.

Clinical manifestations were mostly erythematous plaque type or nodular plaque type. These results led to the conclusion that melanization could affect binding and, consequently, the susceptibility of fungal cells to antimicrobial compounds Nimrichter et al. Cell Host Microbe
