Fungal species, which were shown to colonize consistently on the skin surface of the breast region of adult (1 year old) white leghorn fowl, were identified as Aspergillus sydowii, A. tamarii, A. rugulosus and Absidia corymbifera. Of these, A. sydowii and A. tamarii were the dominant forms. Two species of fungi, namely, Aspergillus niger and Scopulariopsis brevicaulis were shown to be present i...

During 2016–17, 277 samples of leaf compost, manure, virgin and rhizosphere soil of some plants from Fars and Khuzestan provinces (Iran) were transferred to Mycology Laboratory of the Department of Plant Protection, Shiraz University (Iran). Fungi were recovered by soil plate and soil dilution methods. After purification, the isolates of Mucorales were identified based on growth, morphological ...

Six new N-substituted di- and tributyltin 2-aminoethanethiolates (cysteaminates) have been prepared and characterised by (1)H, (13)C and (119)Sn NMR spectroscopy. All these compounds exhibit a good in vitro antifungal effect against selected types of human pathogenic fungi (Candida albicans, Candida krusei, Candida tropicalis, Candida glabrata, Trichosporon beigelii, Aspergillus fumigatus, Absi...

Pulmonary mucormycosis (PM) is a life-threatening fungal infection in patients with hematologic malignancies, and early and accurate diagnostic modalities are urgently needed. We conducted a polymerase chain reaction (PCR) assay targeting these fungi in peripheral blood from four patients with hematologic malignancies who were strongly suspected of having PM. In these four patients, the Rhizopu...

The comparative virulence of six different strains of Absidia corymbifera for cortisone-treated and untreated Swiss mice was determined. Spores of the six strains were inoculated into mice by the intravenous, intraperitoneal, and intranasal routes. All six strains were found to be virulent in cortisone-treated and untreated mice by the intravenous route. Up to a 16-fold difference in strain vir...

Transformation of fungi by complementation of auxotrophs is generally much more reliable than usage of antibiotic resistance markers. In order to establish such a system for the model zygomycete Absidia glauca, a stable methionine auxotrophic mutant was isolated after X-ray mutagenesis of the minus mating type and characterized at the molecular level. The mutant is disrupted in the coding regio...

The hydroxylation of dehydroepiandrosterone (DHEA) to 7? -hydroxy-5-androstene-17-one (7?-OH-DHEA) and 7?-hydroxy-5-androstene-17-one (7?-OH-DHEA) by Gibberella sp. CICC 2498 Absidia coerulea 41050 was investigated. media ingredients were optimized. Single factors such as the DHEA concentration, culture time, medium volume, inoculum rate individually investigated generate optimum biotransformat...
