The solution structure of a complex between the DNA binding domain of a fungal GATA factor and a 13 base-pair oligonucleotide containing its physiologically relevant CGATAG target sequence has been determined by multidimensional nuclear magnetic resonance spectroscopy. The AREA DNA binding domain, from Aspergillus nidulans, possesses a single Cys2-Cys2 zinc finger module and a basic C-terminal ...
The base composition in moles percent guanine plus cytosine (%GC) of both nuclear and mitochondrial deoxyribonucleic acid (DNA) isolated from the yeastlike and mycelial phases of the dimorphic fungal pathogens Histoplasma capsulatum and Blastomyces dermatitidis was determined by techniques of thermal denaturation and CsCl buoyant density gradient equilibrium centrifugation. The mean observed va...
Invasive aspergillosis is one the major causes of death in hematopoietic and solidtransplantrecipients. One of the most critical problems in medical mycology is theinability to consistently make a convincing and early diagnosis of invasive fungalinfection. Conventional diagnosis methods such as culture-based approaches are limitedby the insufficient accessibility sensitivity and the non-culture...
Invasive fungal infections are a primary cause of morbidity and mortality in patients with hematological malignancies. Establishing a definite diagnosis of invasive fungal infection in febrile neutropenic patients is particularly challenging and time-consuming, but a delay of antifungal treatment leads to higher mortality. This situation has lead to the strategy of initiation "empirical" antifu...
In this study, 51 fungal strains were isolated from decaying wood samples collected from forests located in the Northwest of Tunisia in the vicinity of Bousalem, Ain Draham and Kef. Phylogenetic analysis based on the sequences of the internal transcribed spacers of the ribosomal DNA showed a high diversity among the 51 fungal isolates collection. Representatives of 25 genera and 29 species were...
Phagocytic responses are critical for effective host defense against opportunistic fungal pathogens. Macrophages sample the phagosomal content and orchestrate the innate immune response. Toll-like receptor 9 (TLR9) recognizes unmethylated CpG DNA and is activated by fungal DNA. Here we demonstrate that specific triggering of TLR9 recruitment to the macrophage phagosomal membrane is a conserved ...
Soils and soil-borne microbial communities are probably the greatest source of organismal diversity on Earth. In this soil matrix, plant roots and the soil impacted by those roots – the rhizosphere – host a great diversity of fungi. Fungal community composition in soil and rhizosphere has been assessed by growing fungi from environmental samples in different pure culture media. These studies ha...
