The nomenclature of Aspergillus is important in many fields of research and therefore the strategies for stable and efficient naming are important. The conservation of species names as accepted by the Aspergillus community is described. Published lists of accepted names provide that people who use Aspergillus and Penicillium taxonomies need no longer fear the overturning of names currently used...

INTRODUCTION Chronic necrotizing pulmonary aspergillosis (CNPA) is a cavitary, infectious process of lung parenchyma with slow progressive course. Vascular invasion and dissemination to other organs are unusual. CASE REPORT We presented a 25-year old man with bilineal acute leukaemia who developed pulmonary and systemic symptoms. Chest CT showed nodular consolidations and cavitary lesions in ...

The enzyme activities of Trichoderma viride and Aspergillus niger grown on various waste cellulosic materials such as corncobs, saw dust and sugarcane baggase were tested for a period of 192 hrs. The maximum activity of 0.33 mg/min/ml & 0.026 mg/min/ml of cellulase enzyme were found to be produced on saw dust after 144 hrs by Aspergillus niger & Trichoderma viride, respectively. Corncob showed ...

objective(s): the nosocomial infections by aspergillus species are associated with constructions and increased dust loads in hospital indoors. our main object was to find the environmental sources of aspergillus species causing hospital acquired infections. materials and methods: the clinical and environmental samplings were performed during 18 months from spring 2010 to summer 2011 in imam edu...

The purpose of this study was to evaluate the clinical utility of a quantitative Aspergillus IgG assay for diagnosing chronic pulmonary aspergillosis. We examined Aspergillus-specific IgG levels in patients who met the following criteria: (i) chronic (duration of >3 months) pulmonary or systemic symptoms, (ii) radiological evidence of a progressive (over months or years) pulmonary lesion with s...

Invasive aspergillosis increases in chronic immunosuppressive diseases such as cancer. There is little information about the mechanisms by which Aspergillus infection affects the immune regulation and microenvironment of cancer cells. Hence, this study was aimed at investigating the effect of invasive aspergillosis on immunosurveillance, metastasis, and prognosis of cancer in tumor-bearing mice...

Fungi from the genus Aspergillus are important saprophytes and opportunistic human fungal pathogens that contribute in these and other diverse ways to human well-being. Part of their impact on human well-being stems from the production of small molecular weight secondary metabolites, which may contribute to the ability of these fungi to cause invasive fungal infections and allergic diseases. In...

The actin cytoskeleton is highly conserved among eukaryotes and is essential for cellular processes regulating growth and differentiation. In fungi, filamentous actin (F-actin) orchestrates hyphal tip structure and extension via organization of exocytic and endocytic processes at the hyphal tip. Although highly conserved, there are key differences among actins of fungal species as well as betwe...

BACKGROUND Fungal skull base osteomyelitis (SBO) is a severe complication of otitis externa or sinonasal infection, and is mainly caused by Aspergillus species. Here we investigate innate and adaptive immune responses in patients with Aspergillus SBO to identify defects in the immune response that could explain the susceptibility to this devastating disease. METHODS Peripheral blood mononucle...

Few data exist to describe in vitro patterns of cross-resistance among large collections of clinical Aspergillus isolates, including those of species other than Aspergillus fumigatus. We examined 771 Aspergillus spp. clinical isolates collected from 2000 to 2006 as part of a global antifungal surveillance program (553 A. fumigatus, 76 A. flavus, 59 A. niger, 35 A. terreus, and 24 A. versicolor ...
