Authors: Antonogiannaki EM, Proklou A, Tamiolakis D, Vassalou E, Kondili E Abstract Invasive Aspergillus tracheobronchitis is a relatively rare form of invasive pulmonary aspergillosis characterized by invasion of the tracheobronchial tree by Aspergillus spp. Invasive pulmonary aspergillosis is predominantly detected in severely immunocompromised patients. Notably however, pulmonary and tracheobronchial cases of invasive aspergillosis have also been reported, particularly in the context of severe malaria caused by Plasmodium falciparum. Herein, we present a case of invasive Aspergillus tracheobronchitis in a patien...

This article describes 3 cases of IPA. Two patients had a history of chronic obstructive pulmonary disease (COPD) and asthma, and the other patient had no underlying diseases. The Aspergillus fumigatus gene was found in the bronchoalveolar lavage fluid in all three cases by NGS. This report explores the role of NGS in the diagnosis of IPA and emphasizes that IPA may occur in non-neutropenic patients. PMID: 31105860 [PubMed]

e Piñar Salt mines are among the most extreme environments as they combine darkness, low nutrient availability, and hypersaline conditions. Based on comparative genomics and transcriptomics, we describe in this work the adaptive strategies of the true halophilic fungus Aspergillus salisburgensis, found in a salt mine in Austria, and compare this strain to the ex-type halotolerant fungal strain Aspergillus sclerotialis. On a genomic level, A. salisburgensis exhibits a reduced genome size compared to A. sclerotialis, as well as a contraction of genes involved in transport processes. The proteome of A. sclerotialis...

Abstract Domestication refers to artificial selection and breeding of wild species to obtain cultivated variants that thrive in man-made niches and meet human or industrial requirements. Several genotypic and phenotypic signatures of domestication have been described in crops, livestock and pets. However, domestication is not unique to plants and animals. Microbial diversity has also been shaped by the emergence of novel and highly specific man-made environments, like food and beverage fermentations. This allowed rapid adaptation and diversification of various microbes, such as certain Lactococcus, Lactobacillus, ...

This study investigated discrimination and prediction of ochratoxin A (OTA) in three Aspergillus carbonarius strains cultured grape-based medium using E-nose technology and GC-MS analysis. Results showed that these strains cultured medium samples were divided into four groups regarding their log 10 OTA value using an equispaced normal distribution analysis. Partial least squares-discriminant analysis (PLS-DA) revealed that GC-MS PLS-DA model only separated the low OTA level medium samples from the rest OTA level samples, whereas all the OTA level samples were segregated from each other using E-nose PLS-DA model. Partial le...

Abstract The potential antifungal activity of the marine alkaloid 2,2-bis(6-bromo-3-indolyl)ethylamine (URB 1204) was firstly assessed by minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) against different fungi. Then, URB 1204 was applied to a building material experimentally contaminated with selected fungi, in single and mixed species, for determining its potential application in preventing fungal growth. In addition, the over-time protection efficacy of URB 1204 was verified, subjecting the treated building surfaces to natural fungal contamination for 6 weeks. URB 1204 show...
