SREB, a GATA Transcription Factor That Directs Disparate Fates in Blastomyces dermatitidis Including Morphogenesis and Siderophore Biosynthesis
Blastomyces dermatitidis belongs to a group of human pathogenic fungi that exhibit thermal dimorphism. At 22 degrees C, these fungi grow as mold that produce conidia or infectious particles, whereas at 37 degrees C they convert to budding yeast. The ability to switch between these forms is essential for virulence in mammals and may enable these organisms to survive in the soil. To identify gene...
متن کاملFungal Morphology, Iron Homeostasis, and Lipid Metabolism Regulated by a GATA Transcription Factor in Blastomyces dermatitidis
In response to temperature, Blastomyces dermatitidis converts between yeast and mold forms. Knowledge of the mechanism(s) underlying this response to temperature remains limited. In B. dermatitidis, we identified a GATA transcription factor, SREB, important for the transition to mold. Null mutants (SREBΔ) fail to fully complete the conversion to mold and cannot properly regulate siderophore bio...
متن کاملMolecular epidemiology of Blastomyces dermatitidis.
The inhalation of conidia of Blastomyces dermatitidis, a fungus found in soil, causes disease in humans and animals. We studied the genetic diversity of this pathogen by extracting DNA yeasts and analyzing them with a polymerase chain reaction (PCR)-based typing system we developed, which used restriction fragment analysis of amplicons from the regions between the rDNA repeats and allowed us to...
متن کاملEnhanced Toxicity in Chemically Altered Blastomyces Dermatitidis.
Several fungi pathogenic for man, including Blastomyces dermatitidis, Histoplasma capsulatum, and Candida albicans, are known to possess endotoxin activity upon injection into experimental animals (Baker, Am. J. Pathol. 16:463, 1942; Salvin, J. Immunol. 69:89, 1952; Box and Briggs, J. Immunol. 87:485, 1961; Mourad and Friedman, J. Bacteriol. 81:550,1961; Hasenclever and Mitchell, J. Bacteriol. ...
متن کاملInteractions between human granulocytes and Blastomyces dermatitidis.
We studied interactions in vitro between human granulocytes and the yeast-like form of Blastomyces dermatitidis, because granulocytes are prominent in the host response to systemic blastomycosis. In Boyden chamber assays, broth culture filtrates of B. dermatitidis contained levels of granulocyte chemotactic activity that were significantly higher than those present in similar culture filtrates ...
