Recently a species in the genus Talaromyces, a uniseriate species of Aspergillus section Nigri and an isolate each of two widespread species, Penicillium rubens and P. commune, were reported to produce ochratoxin A. This claim was based on insufficient biological and chemical data. We propose a list of criteria that need to be met before an unexpected mycotoxin producer is reported. There have ...
Background and purpose : Otomycosis(Otitis externa) is an acute, subacte or chronic fungal infection that has exogenous or endogenous origin. The present study was carried out to investigate the etiologic agents and determine risk factore and epidemiological aspects of otomycosis in north- West area of Iran. Materials and methods : Clinical samples of suspected patients were studied in dir...
قارچها به عنوان تولید کننده های ترکیبات فعال بیولوژیک از جمله آنتی بیوتیک ها، توکسین ها، آنزیم ها و سایر اثرات بیولوژیکی شناخته شده اند. در این پژوهش قابلیت بازداری از رشد برخی باکتری ها، توسط پنجاه گونه قارچی مختلف متعلق به ده جنس مختلفaspergillus ، penicillium،trichoderma ، myrothecium، paecilomyces، mucor، absidia، syncephalastrum، cuninghamella و mortierella مورد بررسی قرار گرفت. سپس تفکیک ...
Background and aims Aspergillus terreus Thom is a pathogen of public health and agricultural importance for its seamless abilities to expand its ecological niche. The aim of this study was holistically to investigate A. terreus morphological and immunoadaptations and their implication in antifungal resistance and proliferation during infection. Materials and methods In-depth unstructured mini...

The aim of the present study was to identify retrospectively trends in the species distributions and the susceptibility patterns of Aspergillus species causing fungal infections in Spanish medical centers from 2000 to 2002. The susceptibilities of 338 isolates to amphotericin B, itraconazole, and voriconazole were tested. Aspergillus fumigatus was the most common species (54.7%), followed by As...
Antifungal agents may differ in their fungicidal activities against Aspergillus spp. In order to compare the fungicidal activities of voriconazole and amphotericin B against 40 isolates of Aspergillus fumigatus, A. flavus, and A. terreus, we developed a new microbroth colorimetric method for assessing fungicidal activities and determining minimal fungicidal concentrations (MFCs). This methodolo...
BACKGROUND Endo-1,4-β-mannanase is an enzyme that can catalyze the random hydrolysis of β-1, 4-mannosidic linkages in the main chain of mannans, glucomannans and galactomannans and has a number of applications in different biotechnology industries. Penicillium oxalicum is a powerful hemicellulase-producing fungus (Bioresour Technol 123:117-124, 2012); however, few previous studies have focused ...
Fungal species of the genus Aspergillus play significant roles as model organisms in basic research, as "cell factories" for the production of organic acids, pharmaceuticals or industrially important enzymes and as pathogens causing superficial and invasive infections in animals and humans. The release of the genome sequences of several Aspergillus sp. has paved the way for global analyses of p...
In the indoor environment, people are exposed to several fungal species. Evident dampness is associated with increased respiratory symptoms. To examine the immune responses associated with fungal exposure, mice are often exposed to a single species grown on an agar medium. The aim of this study was to develop an inhalation exposure system to be able to examine responses in mice exposed to mixed...
