This study analyzes Aspergillus isolates from the Spanish National Centre for Microbiology collection, which were identified morphologically as members of Aspergillus section Usti. Strains were identified through the analysis of the Internal Transcribed Spacer regions and partial beta tubulin gene sequences. One Aspergillus pseudodeflectus isolate and eight Aspergillus calidoustus isolates were...

OBJECTIVES To describe the association of Aspergillus with influenza. DESIGN/SETTING/SAMPLE Three case reports of ICU patients with influenza complicated by the isolation of Aspergillus species are described and a review of the literature on the topic was performed. CONCLUSIONS Severe influenza cases can be complicated by Aspergillus infection.

hair samples from 58 healthy camels were examined for the presence of saprophytic fungi. one -hundred and seventy-four samples were obtained from three different locations of dromedary camel's body. several fungal specific media were used for isolating and identifying the saprophytes. fungal isolates belonged to 15 genera. the most common in order of frequency were members of the genera aspergi...

Sensor histidine kinases (HKs) are important factors that control cellular growth in response to environmental conditions. The expression of 15 HKs from Aspergillus nidulans was analyzed by quantitative real-time PCR under vegetative, asexual, and sexual growth conditions. Most HKs were highly expressed during asexual growth. All HK gene-disrupted strains produced reactive oxygen species (ROS)....

Aspergillus fumigatus and related species are widely distributed in nature. The majority of the species belonging to this genus are saprophytic in nature. Only a few species including A. fumigatus are capable of causing diseases in man. These opportunistic agents may cause infection or allergy in susceptible individuals. These fungi also cause diseases in animals, birds, and in plants. In addit...

Aspergillus subgenus Circumdati section Flavi includes species with usually biseriate conidial heads, in shades of yellow-green to brown, and dark sclerotia. Several species assigned to this section are either important mycotoxin producers including aflatoxins, cyclopiazonic acid, ochratoxins and kojic acid, or are used in oriental food fermentation processes and as hosts for heterologous gene ...

BACKGROUND Indoor dampness increases the risk of indoor fungal growth. A complex interaction between occupant behaviors and the built environment are thought to affect indoor fungal concentrations and species diversity, which are believed to increase the risk of having asthma, exacerbation of asthma symptoms, or both. To date, no systematic review has investigated this relationship. OBJECTIVE...

The present work was carried out to study the mycobiota of cocoa beans from farm to chocolate. Four hundred and ninety-four samples were analyzed at various stages of cocoa processing: (i) primary stage at the farm (fermentation, drying, and storage), (ii) secondary stage at processing (testa, nibs, liquor, butter, cake and powder) and (iii) the final chocolate product (dark, milk, white and po...

In the present study, a novel non radioactive digoxigenen labelled PCR-DNA probe was developed targeting nor-1 gene to assess the contamination of aflatoxigenic Aspergillus species in food grain samples from Southern parts of India. The sensitivity of developed PCR-DNA probe was determined to be 10 pg of genomic DNA and 1 pg of purified PCR product. The specificity of the DNA probe was validate...
