CONCLUSIONS: This case highlights the importance of early and accurate identification, debridement, and systemic antifungals to prevent widespread infection. With changes in antifungal care over recent years, engaging infectious disease physicians during treatment is recommended. PMID: 30312971 [PubMed - in process]

In this study, we aimed at their production by the oleaginous filamentous fungus Aspergillus oryzae via metabolic engineering. Three genes encoding enzymes involved in the synthesis of DGLA and ARA, were isolated from the filamentous fungus Mortierella alpina that produces ARA in a triacylglycerol form. These genes were concatenated to promoters and terminators of highly expressed genes of A. oryzae, and the concatenated DNA fragments were further concatenated with each other to generate a single DNA fragment in the form of a biosynthetic gene cluster. By homologous recombination, the resulting DNA fragment was integr...

Zayed, Gul Shad AliAbstractTaxol is a blockbuster anticancer drug that commercially synthesized from 10-decaetylbaccatin III intermediate of Taxus baccata, however, this technology has been challenged by reproducibility and association of unwanted compounds. Recently, endophytic fungi with fast growing and feasibility of molecular engineering raise the hope for sustainable production of Taxol, unfortunately the loss of their productivity with multiple subculturing is the m...

Zaky, Yangliu Liu, Yaoyao Chen, Lu Liu, Siting Li, Yingmin JiaAbstractA new extracellular xylanase was purified from a non-toxic mesophilic fungus Aspergillus flavus, and characterized as the β-1, 4-endoxylanase (designated as AfXynA) that appeared in a single protein band on SDS-PAGE with a molecular mass of 20.2 kDa, which is different from all other reported xylanases from the same strain. The AfXynA exhibited a specific activity of 838.2 U/mg. Its optimal temperature and pH were determined ...

Ingle, Mahendra RaiAbstractAn approach for green synthesis of magnesium hydroxide nanoparticles [Mg(OH)2NPs] has been developed and its efficacy in seed germination, in vitro and in vivo plant growth promotion was studied on Zea mays at different concentrations. Mg(OH)2NPs at 500 ppm showed improved seed germination (100%) and growth. The effect of Mg(OH)2NPs was analyzed by measurement of plants height and chlorophyll a fluorescence using plant efficiency analyzer. The seedlings grown...

Molds and their toxins have attracted much attention worldwide due to the important economic losses related to their effects on human health and domestic and international trade. Although more than 400 mycotoxins have been identified, most studies have focused on aflatoxins, ochratoxin A, fusarium toxins, zearalenone, patulin, and trichothecenes owing to their relatio...

Abstract Aspergillus galactomannan immunoassay is a main diagnostic and monitoring tool in medical mycology. However, the specificity of the method can be skewered by the presence of several other fungi. Trying to diagnose a possible fungal infection of the lower respiratory tract in a haematology patient, it appeared that the fungus Trichoderma longibrachiatum is an additional probable cause of positive galactomannan results. Although, that Trichoderma is a rare but emerging pathogen in immunocompromised patients, the above information could be a caution point in the clinical evaluation of diagnostic results. ...
