There is considerable evidence supporting a role for mold exposure in the pathogenesis and expression of childhood asthma. Aspergillus versicolor and Cladosporium cladosporioides are common molds that have been implicated in asthma. In a model of mold-induced asthma, mice were repeatedly exposed to either A. versicolor or C. cladosporioides spores. The two molds induced distinct phenotypes, and...
There is little information on the indoor environment in hotels. Analysis of fungal DNA by quantitative PCR (qPCR) is a new method which can detect general and specific sequences. Dust was collected through swab sampling of door frames in 69 hotel rooms in 20 countries in Europe and Asia (2007-2009). Five sequences were detected by qPCR: total fungal DNA, Aspergillus and Penicillium DNA (Asp/Pe...
Fungal rhinosinusitis is an increasingly recognized entity in both immunocompromised as well as immunocompetent patients. Aspergillus spp. is commonest of all causative fungi. A case of chronic fungal rhinosinusitis in a16-year-old immunocompetent female is reported. Presenting symptoms were bilateral nasal block, discharge, and change of voice. Initially, it was diagnosed as nasal polyposis. M...
Aspergillus spp. often colonise the respiratory tract of critically ill patients in intensive care units and subsequently cause invasive disease. The risk of developing invasive disease is more in immunocompromised patients. Here we report a case of fatal invasive pulmonary aspergillosis caused by Aspergillus versicolor in a post-operative patient on mechanical ventilation, who did not respond ...

Most studies on molds focus on Alternaria alternata and Aspergillus fumigatus. Here, we report on inflammatory and allergenic properties of more typical indoor species Aspergillus versicolor, P. chrysogenum, C. cladosporioïdes, and C. sphaerospermum that were compared to A. alternata and A. fumigatus. In a mouse model, after intranasal instillation, A. alternaria, A. versicolor, and C. sphaeros...
Aspergillus sp. Z5, isolated from the gut of marine isopods, produces prolific secondary metabolites with new structure and bioactivity. Here, we report the draft sequence of the approximately 33.8-Mbp genome of this strain. To the best of our knowledge, this is the first genome sequence of Aspergillus strain isolated from marine isopod Ligia oceanica. The phylogenetic analysis supported that t...
The individual colonies of a partially degenerated culture of Aspergillus versicolor vary widely in their ability to produce an antibiotic active against Trichophyton rubrum. Mutagenic treatment with nitrous acid or ultraviolet light gave potent colonies. Nitrous acid gave better results in terms of stability and yield. This treatment may therefore prove useful in the regeneration of partially ...
Pulmonary exposure to Aspergillus fumigatus has been associated with morbidity and mortality, particularly in immunocompromised individuals. A. fumigatus conidia produce β-glucan, proteases, and other immunostimulatory factors upon germination. Murine models have shown that the ability of A. fumigatus to germinate at physiological temperature may be an important factor that facilitates invasive...
