A nontoxigenic Aspergillus flavus strain, K49, is currently being tested as a biological control agent in corn fields in the Mississippi Delta. However, little is known about the overall genetic diversity of A. flavus from year to year in corn fields and specifically in Mississippi. Our objective was to assess the genetic variability of A. flavus isolates from different seasons, inoculum source...

Invasive aspergillosis (IA), a complication with high mortality rates, especially in disseminated IA with cerebral involvement, is difficult to diagnose. Biopsy of cerebral lesions is often not feasible, and culture of Aspergillus spp. from cerebrospinal fluid (CSF) is frequently negative. New molecular methods have emerged for diagnosing IA. So far, there are only few reports of Aspergillus DN...

BACKGROUND AND PURPOSE Pistacia atlantica, which belongs to the Anacardiaceae family, grows in the Zagrossian region of Iran. The aim of this study was to evaluate the antifungal properties of Pistacia atlantica and olive leaf extracts against different fungal species. MATERIALS AND METHODS In this study, we assessed the activities of olive leaf extracts and Pistacia atlantica leaf and fruit ...

Aflatoxin B₁, a type of highly toxic mycotoxin produced by some species belonging to the Aspergillus genus, such as Aspergillus flavus and Aspergillus parasiticus, is widely distributed in feed matrices. Here, coumarin was used as the sole carbon source to screen microorganism strains that were isolated from types of feed ingredients. Only one isolate (ND-1) was able to degrade aflatoxin B₁ aft...

Aspergillus species are the most common causes of invasive mould infections in immunocompromised patients. The introduction of new antifungal agents and recent reports of resistance emerging during treatment of Aspergillus infections have highlighted the need for in vitro susceptibility-testing. Various testing procedures have been proposed, including macrodilution and microdilution, agar diffu...

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...
