Deletion C-terminal thioesterase abolishes melanin biosynthesis, affects metabolism and reduces the pathogenesis of < i > Fonsecaea monophora < /i >
In conclusion, we confirmed the crucial role of C-terminal TE in maintaining fully function ofpks1 inF.monophora. Deletion of TE negatively impacts on the synthesis of melanin and metabolites that eventually affect growth and virulence ofF.monophora. Any potential inhibitor of TE then could be a novel antifungal target for drug development. (Source: PLoS Neglected Tropical Diseases)

Pathogenicity and Growth Conditions Modulate Fonsecaea Extracellular Vesicles ’ Ability to Interact With Macrophages
Chromoblastomycosis (CBM) is a chronic cutaneous and subcutaneous mycosis caused by black, dimorphic, and filamentous fungi of the Herpothrichiellaceae family, such as species of the genus Fonsecaea. These fungi can switch between the saprophytic forms (conidia and hyphae) and the pathogenic form, the muriform cells (MCs), which is considered an essential mechanism for fungal virulence. Nearly all types of cells can produce membranous structures formed by a lipid bilayer that communicate extracellularly with other cells, known as “extracellular vesicles” (EVs), which may act as virulence factors, as observed for severa...

Doubly Misdiagnosed: Exophiala Masquerading as Squamous Cell Carcinoma and Chromoblastomycosis
Abstract: Deep cutaneous fungal infections (DCFI) can arise in the setting of skin trauma and immunosuppression. DCFI may be secondary to chromoblastomycosis, which is typically characterized by pseudoepitheliomatous hyperplasia histologically and can be mistaken for squamous cell carcinoma. In addition, “copper penny” spore–like pigmented yeast forms on Grocott's methenamine silver stain can suggest chromoblastomycosis, but this finding is not specific. By contrast, phaeohyphomycosis characteristically exhibits circumscribed pseudocyst or abscess on histopathology, and both yeast and hyphae can be seen. Our case...

Reviewing the Etiologic Agents, Microbe-Host Relationship, Immune Response, Diagnosis, and Treatment in Chromoblastomycosis
J Immunol Res. 2021 Nov 1;2021:9742832. doi: 10.1155/2021/9742832. eCollection 2021.ABSTRACTChromoblastomycosis (CBM) is a neglected human disease, caused by different species of pigmented dematiaceous fungi that cause subcutaneous infections. This disease has been considered an occupational disease, occurring among people working in the field of agriculture, particularly in low-income countries. In 1914, the first case of CBM was described in Brazil, and although efforts have been made, few scientific and technological advances have been made in this area. In the field of fungi and host cell relationship, a very reduced n...
