Zygomycetes and their alleged sister taxon, the microsporidia, exclusively share the presence of a cluster of three genes encoding a sugar transporter, a high mobility group (HMG)-type transcription factor, and an RNA helicase. In zygomycetes, the HMG-type transcription factor acts as the sole sex determinant. This intimately ties the evolutionary history of this gene cluster to the evolution o...
Zygomycetes cause serious invasive infections, predominantly in immunocompromised and diabetic patients with poor prognoses and limited therapeutic options. We compared the antifungal function of human polymorphonuclear leukocytes (PMNLs) against hyphae of Rhizopus oryzae and R. microsporus, the most frequently isolated zygomycetes, with that against the less frequently isolated Absidia corymbi...
Windipila spinifera from the Rhynie cherts is a spheroidal microfossil enveloped in hyphal mantle which extend prominent spines and otherwise shaped projections. It believed to be reproductive unit of fungus Glomeromycota or zygomycetes, but features determine systematic affinities have not hitherto been documented. This study describes new specimen W. that contains single spherical structure h...
Aspergillosis and candidosis remain the most prevalent opportunistic fungal infections in immunocompromised patients, but diseases caused by the Zygomycetes have become of increasing importance. Exposure to antimycotic drugs with no activity against zygomycetes may be a new risk factor and an explanation for the increasing incidence of zygomycosis. The latter infection occurs only rarely in imm...
The in vitro interaction of antifungals with immunosuppressive drugs was evaluated against zygomycetes. The combination of amphotericin B with cyclosporine, rapamycin, or tacrolimus was synergistic for 90%, 70%, and 30% of the isolates, respectively. For posaconazole, itraconazole, and ravuconazole, synergy was more frequently observed with cyclosporine than with rapamycin or tacrolimus and ant...
Zygomycete fungi were classified as a single phylum, Zygomycota, based on sexual reproduction by zygospores, frequent asexual reproduction by sporangia, absence of multicellular sporocarps, and production of coenocytic hyphae, all with some exceptions. Molecular phylogenies based on one or a few genes did not support the monophyly of the phylum, however, and the phylum was subsequently abandone...
Twenty-four patients with cancer met predetermined criteria for a diagnosis of zygomycosis over a 10-year period at our institution. All had hematologic malignancy, and most had either neutropenia or steroid use as a risk factor. Pulmonary involvement mimicking invasive aspergillosis was the most common presentation, and dissemination was seen in 58% of patients on whom autopsies were performed...
mushroom production units of kermanshah province were sampled during 2012-13, and 50 fungal isolates were obtained. verticillium fungicola with the most number of isolates, tricoderma harzianum and trichothecium sp. were the most frequent fungi associated with the cultivated mushroom, agaricus bisporus. seven isolates were obtained from the cap of a. bisporus with following characteristics: col...
