BACKGROUND Aspergillus tubingensis is a black Aspergillus belonging to the Aspergillus section Nigri, which includes species that morphologically resemble Aspergillus niger. Recent developments in species determination have resulted in clinical isolates presumed to be Aspergillus niger being reclassified as Aspergillus tubingensis by sequencing. We present a report of a patient with an osteomye...

Pedetan is processed food of seasoned sardine fish (Sardinella lemuru) which preserved by drying. Isolation and identification mold that contaminated the pedetan have been taken from 10 villages are production centers in Jembrana Regency. Molds can contaminate during storage, include Aspergillus flavus, aculeatus, niger, tubingensis. In this research, composition seasoning producer was used to ...

PURPOSE To report 2 cases of keratomycosis caused by Aspergillus tubingensis. METHODS The therapeutic courses were recorded for 2 male patients, 52 and 78 years old, with fungal keratitis caused by black Aspergillus strains. Morphological examination of the isolates was carried out on malt extract agar plates. A segment of the beta-tubulin gene was used for molecular identification. Antifunga...

This work aimed to identify the species distribution of common clinical and environmental isolates of black Aspergilli based on simple restriction fragment length polymorphism (RFLP) analysis of the β-tubulin gene. A total of 149 clinical and environmental strains of black Aspergilli were collected and subjected to preliminary morphological examination. Total genomic DNAs were extracted, and PC...

We report the cloning and characterization of a gene encoding a ferulic acid esterase, faeA, from Aspergillus niger and Aspergillus tubingensis. The A. niger and A. tubingensis genes have a high degree of sequence identity and contain one conserved intron. The gene product, FAEA, was overexpressed in wild-type A. tubingensis and a protease-deficient A. niger mutant. Overexpression of both genes...

A physical and functional map of Aspergillus tubingensis mtDNA type 2b was constructed and compared to Aspergillus niger typeI a mtDNA. The gene content and order, as well as the patterns of restriction sites, were similar. Two unidentified ORFs and several repeat elements were found in the region between the ndhl and ndh4 genes on both mtDNAs. The sizes of the A. niger and A. tubingensis mtDNA...

The native mycobiota of five grape varieties grown in Spain has been studied. Four (Bobal, Tempranillo, Garnacha, and Monastrell) were red varieties and one (Moscatel) was white. The main fungal genera isolated were Alternaria, Cladosporium, and Aspergillus. The isolation frequency of Aspergillus spp. section Nigri in contaminated samples was 82%. Ochratoxin A (OTA) production was assessed usin...

Black aspergilli are among the main causative agents of otomycosis worldwide. In this study, the species assignment of black aspergilli isolated from otomycosis cases in Iran was carried out using sequence analysis of part of the calmodulin gene. The results indicate that Aspergillus niger is not the only black Aspergillus species involved in otomycosis cases in Iran: Aspergillus awamori and As...

Essential oils have been used since ancient times in traditional medicine and agri-food science to preserve food, combat human diseases. (EOs) from clove rosemary, obtained by hydro-distillation, were analyzed GC/MS evaluated for their antifungal activity against strains of Aspergillus tubingensis A. luchuensis effect on ochratoxin A (OTA) production these fungi. The major constituent EO was eu...
