Phylogenetic Diversity and Extracellular Enzymatic Activities of Yeasts and Yeast‐Like Fungi Isolated From Qualea grandiflora (Vochysiaceae) in Cerrado Areas in Northern Minas Gerais, Brazil

International Journal of Microbiology, Volume 2025, Issue 1, 2025.
The Brazilian savannah, Cerrado, a Brazilian phytophysiognomy, is an entire biome that contains as well as other Brazilian ecosystems, a vast biodiversity of microorganisms associated with native plants. Plant species of the Cerrado have attracted attention due to the still limited knowledge regarding their associated microbiota and the possible ...

Exophiala dermatitidis Eye Infection: Case Report and Literature Review

Journal of Fungi
Exophiala endophthalmitis of exogenous origin is an exceptionally rare but severe ocular infection, characterized by diagnostic delays, limited therapeutic guidance, and frequently poor outcomes. Herein, we report one new case of an 80-year-old woman who

Deletion of the polyketide synthase‐encoding gene pks1 prevents melanization in the extremophilic fungus Cryomyces antarcticus

IUBMB Life, Volume 76, Issue 12, Page 1072-1090, December 2024.
Abstract Cryomyces antarcticus, a melanized cryptoendolithic fungus endemic to Antarctica, can tolerate environmental conditions as severe as those in space. Particularly, its ability to withstand ionizing radiation has been attributed to the presence of thick and highly melanized cell walls, which—according to a previous investigation—may contain both

In vitro study on synergistic antifungal effects of docetaxel combined with azoles against dematiaceous fungi and Aspergillus niger

Frontiers in Microbiology
BackgroundDematiaceous fungal infections are frequently encountered in clinical practice with no unified treatment. Drug combination reduces drug resistance, and repurposed clinical drugs as synergists show promise in aiding azoles against ...

Assessment of the cyst wall and surface microbiota in dormant embryos of the Antarctic calanoid copepod, Boeckella poppei

Environmental Microbiology Reports, Volume 16, Issue 6, December 2024.
A diverse microbiome colonizes the surface of dormant copepod embryos, which can survive for ~200 years in lake sediments. During dormancy, the outer two layers of a five‐layered cyst wall break apart, while the third layer remains undamaged, despite the presence of microbial species with chitinase genes.

Polyketide Trimming Shapes Dihydroxynaphthalene‐Melanin and Anthraquinone Pigments

Advanced Science, Volume 11, Issue 22, June 12, 2024.
Vital Pigment Functions: Anthraquinones and dihydroxynaphthalene‐melanins play roles in cancer therapy or act as virulence factors. Protein crystallography, along with structure‐based mutagenesis and activity assays, provides atomic insights into polyketide trimming, ring formation, and thioester hydrolysis during AQ and DHN‐melanin biosynthesis in ...

Exophiala dermatitidis isolates from various sources: using alternative invertebrate host organisms (Caenorhabditis elegans and Galleria mellonella) to determine virulence

Scientific Reports, 2018
Exophiala dermatitidis causes chromoblastomycosis, phaeohyphomycosis and fatal infections of the central nervous system of patients with Asian background. It is also found in respiratory secretions from cystic fibrosis (CF) patients.

Importance of calcium to the regulation of polymorphism inWangiella (Exophiala) dermatitidis [PDF]

Medical Mycology, 1997
Critical steps implicated in the polymorphism of Wangiella dermatitidis were found to be sensitive to calcium ion availability. When grown in a defined, synthetic medium under various pH and temperature conditions, two thresholds of calcium ion concentrations were identified: a lower concentration favouring non-polarized growth leading to multicellular

Subcutaneous phaeohyphomycosis: A rare case

Dermatology Reports, 2019
Phaeohyphomycosis is a rare fungal infection caused by melanized fungi which usually involve the skin and subcutaneous tissue. It is an infrequent cause of infection in human beings. Common clinical manifestations are subcutaneous cystic swellings, which
