The susceptibility to amphotericin B was variable (MIC: 0.5 - > 8 mg/L), with no specific distinction according to Rasamsonia species. Finally, all isolates exhibited low MICs to micafungin (0.0312 - 0.125 mg/L).Altogether, our results show that MALDI-TOF/MS is a powerful tool for rapid...
ORIGINAL PAPER Rasamsonia, a new genus comprising thermotolerant Based on phenotypic and physiological characters and molecular data, we propose Rasamsonia gen. nov. to accommodate these species. This new genus is distinct from other genera of the Trichocomaceae in being thermotolerant or thermophilic...
Rasamsonia, a new genus comprising thermotolerant and thermophilic Talaromyces and Geosmithia species: The phylogenetic relationship
Rasamsonia argillacea (formerly known as Geosmithia argillacea) is a fungus recently recognized as a pathogen of immunocompromised patients. Here we report the first case of Rasamsonia infection in an immunocompetent host, presenting as a pulmonary and aortic graft infection. Its morphological simila...
argillaceum' or 'Rasamsonia'. The first reported case of infection due to the R. argillacea species complex was published in 2009, concerning an infection in a German shepherd dog.[15] Since that date, these fungi have been identified regularly, and 80 cases were reported in the literature...
Engineering of one the loops covering the active site tunnel of Cellobiohydrolase I from Rasamsonia emersonii reveals an inverse affinity/activity relationship. The authors show that replacement of N194 and particularly N197 with alanine results in variants with significantly reduced substrate affinity ...
Rasamsonia is a recently established genus including thermotolerant or thermophilic species, five of which have been isolated from humans, including the emerging pathogen R. argillacea. A new species, R. pulvericola, was recovered from one residence in Songkhla, Thailand, and is morphologically ...
The three pre-transplant strains were previously misidentified as Paecilomyces at the time of isolation but were corrected as Rasamsonia at a post-hoc analysis by DNA sequencing. In order to determine the relatedness of all five Rasamsonia strains, they were genotyped using random amplified ...
The mode-of-action of two α-glucuronidases was demonstrated, both obtained from the fungusRasamsonia emersonii; one belonging to the glycoside hydrolase (GH) family 67 (ReGH67) and the other to GH115 (ReGH115). Both enzymes functioned optimal at around pH 4 and 70 °C.ReGH67 was able...
Since 2010, colonizations/infections by Rasamsonia argillacea species complex, previously known as Geosmithia argillacea, have been regularly reported in literature. We reviewed all available cases focusing on pathogenesis and clinical relevance. The number of cases may be underestimated, as these fung...
